Funding shortfall could shut down bioterrorism lab

The ability of the Seattle area to detect its recent ricin letters was due entirely to a regional bioterrorism lab, the same lab which is now at risk of closure. Local officials were quick to point out that without the local lab, the suspicious substance would have had to be shipped to a different lab nearly 10 hours away. “If you have an instance where you have possible exposure minutes and hours count,”  said the local Sheriff, Ozzie Knezovich. Bioterrorism labs are critical points of first response.

KXLY – “With just one full time employee the lab costs $170,000 to operate each year. It serves not only Spokane but bioterrorism services for all of Eastern Washington and North Idaho. In the last seven years its tested more than 70 samples including the suspicious backpack found at the Martin Luther King Jr. Day Unity March in 2011. State Representative Marcus Riccelli from Spokane said its not just the high profile cases we hear about, but the tests that come back negative that justify keeping the lab. However the most recent work done at the lab in the Ricin investigation is the perfect example of why these local officials keeping the lab open is worth fighting for.”

How Nature Builds A Pandemic Flu Virus

Why isn’t H7N9 ravaging across the planet? Or MERS, for that matter? Not for want of capability. Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases, conducted a study examining the genomes of past pandemic flu strains. The results? It turns out that since 1957, all our most virulent pandemic strains have evolved from the 1918 Spanish ( H1N1) strain.  Which isn’t to say the H7N9 can’t still mutate.

NPR – “Here’s a sobering thought: Wild birds — including city pigeons and ubiquitous Canada geese — carry 170 different types of bird flu. You know, all those viruses with the Hs and Ns in their names, like H1N1 and H5N1. Only a dozen of these viruses have infected humans so far, but many of those have been deadly, and three of them have caused global flu pandemics.Does every bird flu that leaps into people have the potential to turn into the next “big one” that spreads rapidly around the world?”

MERS Virus May Never Become Big Threat in U.S., Experts Say

The WHO recently reported another death from the Middle Eastern Respiratory Syndrome (MERS), bringing the total number of case fatalities to 31. With just 55 total cases, there is no question of the virus’ virulence. In fact, the Obama Administration has declared the virus a public health emergency – not due to fears of a significant outbreak, but so as to speed up testing and diagnostic capabilities.  However, there has been significant recent debate surrounding the virus’ pandemic potential. While significant mutations leading to easier transmission remain possible, MERS in its current form does not seem to pose a significant pandemic threat.

USNWR – “‘Anytime there is a new virus that has the potential to kill people, we ought to take it seriously,’ said Dr. Marc Siegel, an associate professor of medicine at NYU Langone Medical Center in New York City. But while Siegel believes the virus’s spread should be tracked and studied, he doubts it will ever become a real threat. ‘Fear is the biggest virus going,’ he said. ‘The amount of concern is already outweighing the risk. People have seen Contagion too many times.'”

Obama Administration Seeks To Ease Approvals For Antibiotics

While not as attention-grabbing as MERS or H7N9 (bacteria always get the shaft), the rise of antibiotic-resistant bacterial infections is a growing concern. One of the ongoing difficulties in developing new drugs is lack of sufficient financial incentives – antibiotics tend to be less profitable than drugs for more common concerns (high blood pressure, etc).

NPR – “[The Obama Administration is] investing tens of millions in private drug companies to foster new germ-killing drugs. It’s setting up a new research network to develop new antibiotics. And, most controversially, federal health officials are pushing to loosen up the approval process for new antibiotics targeted at patients with life-threatening infections and dwindling treatment options. ‘Where we’re talking about life-threatening illnesses, you can do much less study and get those drugs out there — if in fact they’ll be limited to those kinds of uses,’ Dr. Janet Woodcock, the chief drug official at the Food and Drug Administration, tells Shots.”

Health officials rule out Ebola outbreak in DR Congo

News because it’s not Ebola. Last week, the UN announced six suspected cases of Ebola in the DRC, with three fatalities. However, following testing at the National Institute of Biomedical Research in Kinshasa, Ebola was ruled out, despite symptoms including severe hemorrhaging.  Possibly yellow fever?

Channel News Asia – “A senior health ministry official in the Democratic Republic of Congo on Monday ruled out an Ebola outbreak in the northeast of the country, after possible cases were reported by United Nations staff. OCHA  [UN Office for the Coordination of Humanitarian Affairs] had announced suspect cases recorded between May 1 and May 12 at Mongo in the Bas-Uele district of the northeastern Orientale province, about 240 kilometres (150 miles) from Isiro, where the last Ebola outbreak killed 34 people out of 62 confirmed cases between May and November 2012.”

SARS-like virus patent complicating diagnosis: Saudi

If you’re shaking your head at recent news detailing the spread of the novel coronavirus, and wondering why officials in these countries can’t seem to keep the virus contained, wait a second. One of the reasons health officials in the Middle East are struggling with quick diagnosis is that Saudi Arabia already entered into bilateral agreements with certain drug companies, resulting in the patenting of the virus. This means that every time a new lab (say in a new country or region) wants to work with the virus (due to its emergence locally), they need to get permission. Now, the virus was patented for reasons of vaccine and anti-viral drug development. However, instances like this get to the heart of the ongoing difficulties in the relationship between big pharma and government in relation to vaccines and drug development.

AFP – “WHO chief Margaret Chan expressed outrage at the information. ‘Why would your scientists send specimens out to other laboratories on a bilateral manner and allow other people to take intellectual property right on new disease?’ she asked. ‘Any new disease is full of uncertainty,’ she said…’I will follow it up. I will look at the legal implications together with the Kingdom of Saudi Arabia. No IP (intellectual property) should stand in the way of you, the countries of the world, to protect your people,’ she told the [WHO] delegates to thundering applause.”

Swine Flu Pandemic of 2009 More Deadly for Younger Adults

It’s good to be young, unless a swine flu pandemic happens to be raging. According to new study, the 2009 H1N1 virus was especially virulent in the population under 65. Why? Those over 65 years had some degree of prior immunity, due to exposure to similar strains in their past – a phenomena known as “antigenic recycling”.

Science Daily – “The bulk of pneumonia and influenza deaths typically occur in people older than 65, but when H1N1 became the dominant flu strain in 2009, the accompanying rise in pneumonia and flu deaths took place within age groups that usually have low mortality rates. Overall, there were 53,692 pneumonia and influenza deaths in 2009, of which 2,438 were considered “excess,” or above the number expected. In 2010, there were about 50,000 deaths from pneumonia and flu, of which 196 were considered excess.”

H7n9 Bird Flu Virus Is Capable of Human Spread, Ferret Studies Show

Life is hard for ferrets (image credit: B. Lilly/Flickr)

In case you were wondering, H7N9 is in fact entirely capable of spread between humans. In a study which will no doubt launch another round of polemic debate, researchers in China infected ferrets with the virus strain, and recorded transmission of the virus to other ferrets located four inches away. The research is expected to help Chinese containment and response efforts, should the virus become more virulent. The last new case of H7N9 occurred on May 8th.

Bloomberg – “The findings support the need to reconsider management of live poultry markets, especially in urban areas, in case H7N9 becomes endemic in poultry, increasing the opportunities for the virus to evolve ‘to acquire human-to-human transmissibility,’ the authors said. ‘If this virus acquires the ability to efficiently transmit from human-to-human, extensive spread of this virus may be inevitable, as quarantine measures will lag behind its spread,’ the Chinese researchers said.”

Universal flu jab ‘edges closer’

The pharmaceutical company Sanofi has developed a virus/protein hybrid that may protect against multiple strains of flu. The vaccine fuses the highly conserved H1 glycoproteins to a “transporter protein”, which then (for some reason) form spontaneous spheres. In ferret trials, the vaccine offered protection to numerous different H1 strains. Still, flu viruses are notoriously good at mutating – no word yet on if the virus would remain viable in instances of antigenic drift.

BBC News– “Prof Sarah Gilbert, who works on universal vaccines at Oxford University, told BBC News: ‘It is an improvement on the current vaccine. It’s not a ‘universal vaccine’ but it’s definitely a step in the right direction.’ She said it might be able to get over the problems of ‘mis-match’ when there are differences between the seasonal vaccine and the flu being targeted. However, the vaccine has not yet been tested in people. Clinical grade vaccine has not yet been developed so even safety trials are thought to be a year away.”

Synthetic Biologists Engineer A Custom Flu Vaccine In A Week

Within a week of receiving a strain of H7N9 close to the one circulating in China, researchers at Novartis and the J. Craig Venter Institute had synthesized a vaccine. Yes, there are still hurdles to effective mass production, and no the FDA has not yet approved the new strategy, but a week turnaround time is phenomenal. It is significantly easier to send a virus’ genetic code around the world, and have scientists build their own vaccine than to it is to carefully package and send the virus itself.

Popular Science – “That turnaround time is weeks faster than the current best vaccine-making methods…The new method uses synthetic biology, or the creation of biological materials, such as viruses, without using nature’s usual reproductive methods…’I think it does have great potential for more rapidly preparing vaccines for new strains as they evolve,’ Robert Finberg, chair of the University of Massachusetts Medical School and a flu researcher, told the Boston Globe.”

Another H7N9-hit Chinese province ends emergency response

China is winding down it’s H7N9 response as cases of the new flu strain diminish. The most recent province to end it’s emergency response is Zhejiang, where no new cases have been seen in almost a month. Full kudos to China for handling the containment so effectively. Do we think the US would have fared as well?

Xinhua – “Medical observations on all those who had close contact with the H7N9-infected people in Zhejiang have ended, and there have been no further infections, said a statement from the seventh meeting of the Zhejiang provincial prevention and control mechanism for human infections of H7N9, which was held on Thursday. The virus has not been detected among live poultry or in relevant environments over the past three weeks in Zhejiang, the statement added. The province will continue to closely monitor H7N9.”

WHO: Coronavirus Update

The World Health Organization (WHO) continues to monitor the development of the novel coronavirus (nCoV), after two health care  attending to infected patients themselves became ill. Since the virus’ emergence in September, there have been 40 laboratory confirmed cases and 20 fatalities in six countries across the Middle East and Europe.

WHO – “The two patients are health care workers who were exposed to patients with confirmed nCoV. The first patient is a 45-year-old man who became ill on 2 May 2013 and is currently in a critical condition. The second patient is a 43-year-old woman with a coexisting health condition, who became ill on 8 May 2013 and is in a stable condition. Although health care associated transmission has been observed before with nCoV (in Jordan in April 2012), this is the first time health care workers have been diagnosed with nCoV infection after exposure to patients. Health care facilities that provide care for patients with suspected nCoV infection should take appropriate measures to decrease the risk of transmission of the virus to other patients and health care workers. Health care facilities are reminded of the importance of systematic implementation of infection prevention and control (IPC).”

UC Davis researchers find swine flu virus in elephant seals

Yes, elephant seals are that big (Image credit: Daniel Costa/NASA/JPL)

Another reason to keep a safe distance from the already rather frightening elephant seal – they may be carrying H1N1. A UC Davis study examining 900 of the large sea mammals off the Northern Californian coast revealed two asymptomatic carriers and 28 seals who possessed  H1N1 antibodies. Can we please all take a moment to silently thank the poor grad students (and you know  they were grad student) who had to very bravely swab the nasal cavities of 900 different elephant seals?

Sacramento Bee – “The scientists detected the H1N1 virus in free-ranging northern elephant seals off the Central California coast a year after the 2009 human swine flu pandemic began. UC Davis researchers have been studying flu viruses in wild birds and marine mammals since 2007.The aim of the research is to understand how viruses emerge and travel among animals and people, according to a university press release.”

Novel cell line identifies all foot-and-mouth virus serotypes

Plum Island scientists have developed a novel cell line capable of rapidly detecting foot-and-mouth (FMD) disease in field samples. FMD is an incredibly contagious and deadly disease affecting cloven-hoofed animals, for which we do not vaccinate.

Phys.org – “The cell line was created by Agricultural Research Service (ARS) scientists at the Plum Island Animal Disease Center, Orient Point, N.Y. ARS is USDA’s chief intramural scientific research agency. The research, published online in the Journal of Clinical Microbiology, supports the USDA priority of promoting international food security. Being able to rapidly detect the virus during outbreaks would allow researchers to quickly develop the appropriate vaccine among the seven serotypes and dozens of subtypes, thereby saving valuable time and millions of dollars.”

CDC: Majority of pools contaminated by feces

For all of us out there who have been saying, for year, try to avoid public pools, we have vindication. The next time someone dismissively waves away your warnings with that catch-all “chlorine”, forward them this article.

LiveScience – “Researchers at the Centers for Disease Control and Prevention (CDC) found genetic material from E. coli bacteria in 58 percent of public pools they tested during the summer of 2012. They also found genetic material from bacteria called Pseudomonas aeruginosa, whichcan cause skin rashes and ear infections, in 59 percent of pools. The fecal material in pools comes from swimmers not showering before getting into the water, and from incidents of defecation in pools, according to the report.”

Tunisian Is Accused of Proposing Contamination of Water or Air in U.S.

Mr. Ahmed Abassi has been charged with falsifying visa applicant information in order to facilitate terrorism. In recorded conversations with an undercover FBI agent, Abassi describes intentions to use a bacterial pathogen to contaminate air or water supplies. It is unknown whether Abassi possesses the necessary training to do so. Abassi has denied all charges brought against him.

The New York Times – “A Tunisian man has been accused of seeking to develop a terrorist network in the United States and of proposing to poison the water or air to kill up to 100,000 people, federal prosecutors said in court papers unsealed on Thursday. The man, Ahmed Abassi, 26, who came to the United States from Canada in March and was arrested last month at Kennedy International Airport, told the authorities that he may also have ‘radicalized’ one of two men arrested recently in Canada in an alleged Qaeda-linked plot to derail a passenger train.”

France Probes 3 Suspected Cases of SARS-Like Virus

In what seems indicative of  limited person-to-person spread, two people in close contact with France’s first case of the novel coronavirus are believed to be infected with the virus themselves. The first French case become symptomatic following an excursion in Dubai. The hcov-EMC virus, a cousin of SARS, emerged in the Middle East last September,  and caused 18 fatalities out of 30 confirmed cases. Cases of the virus have been seen across the Middle East, as well as the United Kingdom and Germany.

ABC News –  “Since the virus emerged last year, European authorities have put in place monitoring measures. In France, 20 people have already been examined for suspected cases of the virus, but the other 19 turned up negative, Health Minister Marisol Touraine said. Beatrice Degrugillers, a spokeswoman for the regional health agency in France’s Nord-Pas-de-Calais region, said a nurse at the hospital where the man was hospitalized in late April has herself been under watch at the hospital in Douai since Thursday night….A doctor and a former hospital roommate who had each been in contact with the first patient also remain hospitalized. Test results are expected later Friday.”

US invokes emergency act to keep H7N9 flu at bay

Following a declaration that the H7N9 strain of influenza poses a “significant potential for a public health emergency”, the US government has granted emergency use authorization (EUA) for certain portable diagnostic detection kits for the virus. EUA authorization enables the kits to be used immediately in the field without securing prior FDA approval. Clearly we’re all keep a very close eye on the strain’s spread.

New Scientist – “”They are right to be concerned. H7N9 could be a tough adversary: New Scientist has learned that it provokes a weaker immune response than most flu, making vaccines hard to produce. Although H7N9 is not, so far, transmissible between humans, it does cause severe disease in people, is easier to catch than other bird flu strains, and may need only a few mutations to go pandemic. The UK has already given doctors instructions on when to test people for H7N9, and how to manage any with the virus.”

Using Bacteria To Swat Malaria Inside Mosquitoes

Well, it’s definitely innovative. Scientists have shown that infecting mosquitoes with Wolbachia renders them temporarily resistant to malaria. But before we all start throwing our malaria pills by the wayside, there are a couple little problems with this fix. The first is rounding all the mosquites up to infect them with the bacteria in the first place. The second is the inability of Wolbachia to confer lasting resistance. Scientists have managed to mitigate both concerns be engineering a mosquito capable of maintaining and spreading Wolbachia throughout it’s lifetime. Very cool, and possibly very useful.

NPR – “‘Groups have been trying to do this for more than 10 years,’ microbiologist George Dimopoulos, from the Johns Hopkins Malaria Institute, tells Shots. ‘So it’s a landmark achievement.’ The findings, reported Thursday in the journal Science, raise the possibility of one day controlling malaria with the bacteria.’You could just release large number of infected females and establish Wolbachia in a mosquito population…Gradually it would convert a malaria-spreading population to a non-spreading one.’ Specifically, Dimopoulos and his colleagues got Wolbachia to take up permanent residency inside Anopheles stephensi mosquito, the major malaria transmitter in South Asia and the Middle East.”

After hesitating, Kan. House panel OKs NBAF bonds

The Kansas state legislature has approved bonds supporting the construction of the National Bio- and Agr0-Defense Facility at Kansas State University. The new lab would replace the current agricultural  lab located on Plum Island, off New York. The primary goal of the NBAF would be to research highly infectious animal pathogen like foot-and-mouth, in the hopes of further ensuring our nation’s agricultural security.

SF Gate – “Kansas has already authorized $105 million in bonds to help finance the project. State officials expect the lab to create more than 300 new jobs averaging more than $75,000 in salary and benefits.President Barack Obama’s latest proposed federal budget includes $714 million for the new lab. Both the Senate’s bill and the House committee’s plan would prevent the state from issuing the new bonds until the U.S. Department of Homeland Security has signed its contract with the construction company that will build the lab. Also, the federal government would be on the hook for construction cost overruns.”

‘Appalling irresponsibility’: Senior scientists attack Chinese researchers for creating new strains of influenza virus in veterinary laboratory

                                                                      hitthatswitch/Flickr

There has been widespread outcry in the scientific community following publication of a Chinese research study in which the scientists recombined H5N1 with the highly infectious H1N1, in a veterinary laboratory. Look, there is gain-of-function research which contributes to vaccine development or a better understanding of the strain’s possible pathogenicity, and then there’s gain-of-function research which is just tempting fate. Even amongst those scientists who admired the difficulty of the experiment, there was criticism –  “It’s a fabulous piece of virology by the Chinese group and it’s very impressive,” said Professor Wain-Hobson, a renowned virologist at the Pasteur Institute in Paris, “but they haven’t been thinking clearly about what they are doing. It’s very worrying.”  It would be tremendously ironic  to be  wiped out by a strain of flu created with the purported intention of helping stop us being wiped out by the very same strain of flu.

The Independent – “Senior scientists have criticised the “appalling irresponsibility” of researchers in China who have deliberately created new strains of influenza virus in a veterinary laboratory.They warned there is a danger that the new viral strains created by mixing bird-flu virus with human influenza could escape from the laboratory to cause a global pandemic killing millions of people.”

“Lord May of Oxford, a former government chief scientist and past president of the Royal Society, denounced the study published today in the journal Science as doing nothing to further the understanding and prevention of flu pandemics.’They claim they are doing this to help develop vaccines and such like. In fact the real reason is that they are driven by blind ambition with no common sense whatsoever,’ Lord May told The Independent.”

Miss. ricin-letters case headed to grand jury

Following the exoneration of Kevin Paul Curtis, the new suspect in the ricin letters is James Everett Dutschke. Dutschke will face a grand jury in the coming weeks. Investigators linked Dutschke to the case after discovering a dust mask containing traces of  ricin and Dutschke’s DNA. For a full analysis of the ricin case, as well as the Boston bombings, and other “WMD” terrorism, check out the GMU Biodefense Brown Bag Event  next Thursday.

USA Today – “Agents also revealed that the FBI was granted a search warrant for a location outside Dutschke’s home where he may have stored some of his possessions. Officials said they think a printer tied to the letters is at that location. Magistrate Judge S. Allan Alexander ruled that authorities had enough probable cause to send the case to a grand jury. It’s not clear when one would hear evidence in this case.”

Five die of SARS-like virus in Saudi Arabia

The novel coronavirus hCoV-EMC killed another 5 people in Saudi Arabia, bringing the total number of fatalities to sixteen out of 23 total cases. Although similar to SARS, hCoV-EMC targets the kidney, causing rapid failure. However, unlike SARS, the virus does not appear to transmit well person-to-person.

Al Jazeera – “In a statement cited by the Saudi SPA agency late on Wednesday, the ministry said that all the deaths occurred in the Ahsaa province in the oil-rich eastern region of the kingdom, according to the AFP news agency. Known as novel coronavirus or hCoV-EMC, the virus was first detected in mid-2012 and is a cousin of Severe Acute Respiratory Syndrome (SARS), which triggered a scare 10 years ago when it erupted in east Asia, leaping to humans from animal hosts…the ministry gave no figures for how many people have been examined to see if they have the lethal disease”

NYPD will release harmless gas into subway in bio/chem terror response drill

The NYPD, in coordination with the Brookhaven National Laboratory, will conduct experiments involving “tracer gases” this summer to monitor their dissipation speed. It is hoped the experiments will lead to better bio- and chemical detection systems. Don’t ask us why the Russian news has the most detailed coverage of this story (joke, little joke).

RT– “The police will use roughly 200 detectors to monitor the gas. Dubbed the Subway-Surface Air Flow Exchange, the test will be the largest of its kind and organized in cooperation with the energy department’s Brookhaven National Laboratory. They’ll use perfluorocarbon tracer gases (PFTs), which are frequently used to measure potential sites for underground construction…’The NYPD works for the best but plans for the worst when it comes to potentially catastrophic attacks such as ones employing radiological contaminants or weaponized anthrax,’ police commissioner Ray Kelly said in a statement”

Programs to reduce antibiotic use often work

Apparently introducing extra paperwork is enough to deter doctors from prescribing antibiotics, resulting in a measurable  decrease in drug-resistant bacteria in hospitals in just six months. However, by continues education and persuasion, the same decrease in drug-resistant bacteria can be seen within a year. Questions of suggesting extra paperwork as a viable reform measure aside, it makes some sense that the best the way to combat antibiotic resistance would be to start with the doctors.

Reuters – “For the new review, Davey and his colleagues searched medical research databases for high-quality studies that evaluated whether hospital programs to curb the number of antibiotics doctors prescribed worked, didn’t harm patients and reduced the number of drug-resistant bacteria detected or the number of antibiotic-related infections. In the 89 studies from 19 different countries the researchers found, three types of programs were evaluated…Overall, programs that restricted a doctor’s ability to prescribe antibiotics were 32 percent more effective in the first month than those that tried to persuade and educate…After six months, restrictive programs also did a better job at reducing drug-resistant bacteria and antibiotic-related infections, compared to the persuasive programs.”

Developments in the Ricin Letters Case

All charges have been dropped against Paul Kevin Curtis due to lack of evidence. A second person of interest, Everett Dutschke, has been identified and continues to cooperate with authorities. No charges have been brought against Dutschke, who maintains his  innocence.  Investigators have not disclosed any new information in the case.

USA Today – “A Mississippi man whose home and business were searched as part of an investigation into poisoned letters sent to the president and others has dropped out of sight in order to escape the news media spotlight, but is cooperating with authorities, a friend and his attorney said. Everett Dutschke, 45, had his home and former business in Tupelo, Miss., searched in connection with the letters, which allegedly contained ricin. They were sent last week to President Obama, Sen. Roger Wicker of Mississippi and earlier to an 80-year-old Mississippi judge, Sadie Holland.”

(H7N9) Bird Flu Seen Beyond Mainland, in Taiwan

The first case of H7N9 outside mainland China was recorded this week, with a 53-year old Taiwanese man testing positive for the virus Wednesday. Three healthcare attendants treating the man have also developed “undiagnosed respiratory symptoms” fueling concerns about human-to-human transmission. However, with all evidence currently ruling out human-to-human transmission, it seems more plausible the workers are (understandably) more likely “worried well”. To date, the virus has caused 108 cases with 22 fatalities.

Wall Street Journal – “Taiwan reported the first case of a new form of avian flu found outside China’s mainland on Wednesday and said that three health-care workers who treated the patient had developed undiagnosed respiratory symptoms, raising concerns over the virus’s potential for spreading by human-to-human contact. At a news conference earlier in the day in Beijing, global health officials stressed that there had been no confirmed cases of transmission of the virus, called H7N9, between humans. However, they said, researchers were still struggling to understand how the virus was spread and hadn’t ruled out the possibility of human-to-human transmission.”

WHO: New flu passes more easily from bird to human

In his testimony before the WHO, one of the world’s top H7N9 experts has praised China’s response to the emergent flu strain while simultaneously cautioning against it’s lethality.

Post Bulletin – “A new strain of bird flu that emerged in China over the past month is one of the ‘most lethal’ flu viruses so far, worrying health officials because it can jump more easily from birds to humans than the one that started killing people a decade ago, World Health Organization officials said Wednesday. Scientists are watching the virus closely to see if it could spark a global pandemic but say there is little evidence so far that it can spread easily from human to human.”

Scientists confirm new H7N9 bird flu has come from chickens

Chickens have been identified as the reservoir of the new H7N9 strain of flu. China’s closing of its open-air poultry markets soon after the strain’s emergence has been accredited with the decrease in case numbers.  However, scientists remain uncertain as to the strain’s exact mechanism of spread, as a number of cases have had no contact with poultry.

Reuters – “Chinese scientists have confirmed for the first time that a new strain of bird flu that has killed 23 people in China has been transmitted to humans from chickens. In a study published online in the Lancet medical journal, the scientists echoed previous statements from the World Health Organization (WHO) and Chinese officials that there is as yet no evidence of human-to-human transmission of this virus. The H7N9 strain has infected 109 people in China since it was first detected in March. The WHO warned on Wednesday that this strain is ‘one of the most lethal’ flu viruses and is transmitted more easily than the H5N1 strain of bird flu, which has killed hundreds around the world since 2003.”

Mutant version of H5N1 flu virus found to be more preferential to human infection

In a study that will no doubt reignite the gain-of-function research debate, scientists have determined that a laboratory-mutated strain of H5N1 has a much stronger human-cell binding affinity than the wild-type virus. Should we be doing this research in the first place? Do the benefits of being more prepared for a pandemic outweigh the costs of potentially causing the pandemic?

Medical Express – “An international team of bio-researchers has found that a mutant strain of the H5N1 influenza virus (created in a lab) has a 200-fold preference for binding with receptors in human cells, over those found in birds. In describing their research and conclusions in their paper published in the journal Nature, the researchers suggest that the mutant variant is much more like the strains of viruses that caused pandemics in 1918, 1957 and 2009, than it was in its native state.”

It has unfortunately been an exceptionally busy week for those of us studying terrorism, bioterrorism, and pandemics. With new developments in the Boston bombing case,  the ricin letters, and H7N9 in China seemingly happening by the hour, we can guarantee only that news included in this week’s report is current as of this (Friday) morning. In the meantime, our thoughts and good wishes remain with Boston.

Ricin Letters Suspect Paul Kevin Curtis Quickly Identified by Earlier Letters

Paul Kevin Curtis is accused of mailing three letters – one to Mississippi Senator Roger Wicker, one to President Obama, and one to a local justice of the peace – containing the toxin ricin. While the FBI has positively identified the toxin, further testing is needed to determine the concentration and purity of the substance. Curtis, who was identified in part by his signature on the letters – Curtis’ sign off of “KC” on the ricin letters matched previous letters sent to Senator Wicker’s office. Curtis’ family maintains he is mentally ill, and had refused to take appropriate medication.  Now the question becomes – is this terrorism? Keep an eye out for the Mason viewpoint.

ABC News – “Investigators trying to determine who sent ricin-tainted letters to President Obama and other officials quickly traced the messages and signature of the letter to Paul Kevin Curtis, an Elvis impersonator who had written to officials in the past and consistently signed his letters “I am KC and I approve this message,” according to an FBI affidavit.About 15 members of a hazmat team, some totting M4 rifles, entered Curtis’ house today and set up an evidence-gathering area outside. Curtis was formally charged today with sending mail that contained a threat to kill or harm the president and with sending mail containing a threat to injure the president.”

Chinese Government Suspects Human-to-Human Transmission of H7N9 Bird Flu

China is unfortunately following a storied pattern of waiting until critical information is leaked before acknowledging it openly  – according to unofficial sources, as many as 40% of H7N9 cases had no contact with poultry. Exacerbating the pandemic potential of H7N9 are theunique difficulties associated with developing a vaccine to the strain – it’s proven very hard to culture in the lab. However, don’t panic just yet. Even if the virus proves capable of limited human-to-human transmission, further mutations rendering it “casual contact” transmissible would be necessary for a pandemic.

US News – “As the Chinese government openly begins to speculate about the possibility of human-to-human transmission of the H7N9 bird flu strain, an international team of experts, including some from the World Health Organization, have been deployed to investigate the disease in the country. If true, the development would quickly raise concerns of the disease outbreak leading to a pandemic. Flu experts have long warned once a particularly deadly strain of the flu, as H7N9 appears to be – it has killed 17 of the 87 people it has infected – becomes transmissible between humans, it can quickly spread.”

4-year-old bird flu ‘carrier’ worries China

A four-year old in China has emerged as an asymptomatic carrier of H7N9, further complicating epidemiological efforts in the area to discover the source of the outbreak – if you don’t know who’s sick, determining how they became sick becomes very tricky. It is known that the boy’s family handled poultry and fish. Although health investigators are currently looking at “family clusters” of infection,  human-to-human transmission is not suspected.

CNN – “Doctors say the discovery of a 4-year-old carrier of the H7N9 bird flu virus who shows no symptoms of the potentially lethal virus is a worrying development that could make the spread of the infection more difficult to monitor. The Beijing Municipal Health Bureau said the boy was detected from a group of close contacts of the first infection in Beijing and the laboratory results showed the boy was an asymptomatic carrier of the disease.”

Terrorism Updates:

Watertown, Mass., Shut Down in Manhunt for Second Boston Marathon Suspect

The two suspects in the Boston Marathon bombing have been identified as brothers Tamerlan and Dzhokhar Tsarnaev, with the former killed during the night. The manhunt continues throughout Watertown for the Dzhokhar Tsarnaev, who has already killed an MIT police officer and hijacked a car. Residents of the Boston suburb are being ordered to remain indoors as police officers comb the area. The two suspects are believed to be of Chechen descent, but have lived in the United States for several years.

ABC News – “”The at-large suspect is considered armed and extremely dangerous. Police are going door to door in search for the second suspect.’We believe this is a terrorist, we believe this is a man that’s come here to kill people,’ Boston Police Commissioner Ed Davis said.”

Up to 40 Dead in Texas Blast

While preliminary investigations at the fertilizer plant in West, Texas indicate an industrial accident, a full investigation into the source of the explosion will take six months. We’ve included it as a potential act of terrorism due to it’s proximity to Waco (less than 20 miles) and  it’s occurring within two days of both the 20th anniversary of the end of the Waco, Texas siege (today) and the Boston Marathon bombing (Monday). Current numbers indicate 160 injured and at least 35 dead or missing.

Wall Street Journal – “[Mayor] Muska, who is one of more than 30 volunteer firefighters in the city, was on his way to help colleagues put out the initial fire at West Fertilizer Co. that began around 6 p.m. Central time on Wednesday night. Volunteer firefighters in the town of about 2,800 people roughly 80 miles south of Dallas tried to extinguish the fire at the industrial facility.About two hours later, a thunderous explosion ripped through the plant, registering as strong as a magnitude 2.1 earthquake, according to federal seismologists. It sent a column of smoke hundreds of feet into the air.”

Report on 3 in China Who Died From Bird Flu Points to Severity of Strain

Update: 43 cases, 10 fatalities

H7N9 continues apace in China, with the total number of cases up to 43. The virus is especially difficult to track because birds are asymptomatic carriers. While the number of laboratory-confirmed cases is closely monitored, it’s possible there are many more human cases going unnoticed due to a milder disease presentation. Still, there have been no confirmed cases of person-to-person transmission, and scientists in the US have just received the first batch of the virus, and are working on developing a diagnostic.

New York Times – “A report on three of the first patients in China to contract a new strain of bird flu paints a grim portrait of severe pneumonia, septic shock and other complications that damaged the brain, kidney and other organs. All three died…During a telephone news briefing on Thursday, Nancy J. Cox, of the influenza division at the Centers for Disease Control and Prevention, said that several features of H7N9 were particularly troubling: it causes severe disease, it has genetic traits that help it infect mammals and humans probably have no resistance to it.”

Obama proposes $714M for Kansas biodefense project

The National Bio- and Agro-Defense Facility has received the strongest funding endorsement to date from the Obama Administration, with $714 million included for the lab in the President’s FY2014 budget. The lab is slated to replace Plum Island as the nation’s premier   research center on agricultural pathogens.

Wall Street Journal – “Republican Sen. Pat Roberts of Kansas said the recommendation signals the administration’s support for building the $1.15 billion lab, which will study large animal diseases and develop measures to protect the nation’s food supply…Roberts said the proposal will require additional financial commitments from Kansas, which will be worked out by Republican Gov. Sam Brownback and legislators…Kansas agreed when it was awarded the project to contribute 20 percent of the cost of construction. Thus far, the state has issued $105 million in bonds and $35 million from the Kansas Bioscience Authority.”

New tool to identify air travelers with infectious disease developed

Researchers in Toronto, after studying the 2009 H1N1 pandemic, developed basic guidelines for passenger screenings during a pandemic. The results are relatively intuitive – screening passengers as they leave a region in which the pathogen is spreading is more useful than screening them upon arrival at their final destination.

Medical News – “Dr. Khan used his experience analyzing air traffic patterns to review the flights of the nearly 600,000 people who flew out of Mexico in May 2009, the start of the H1N1 pandemic. He found that exit screening would have caused the least disruption to international air traffic. In fact, all air travelers at risk of H1N1 infection could have been assessed as they left one of Mexico’s 36 international airports. Exit screening at just six airports in Mexico coupled with entry screening at two airports in Asia (Shanghai and Tokyo) would have allowed for screening of about 90 per cent of the at-risk travelers worldwide.”

APG working on biosurveillance in response to North Korea threats

Anything that is related to biological warfare and is also called the Kracken is automatically included in the Pandora Report. Here, the Kracken is a 15ft high thermal, acoustic, and infrared sensor.

Baltimore Sun – “While the danger of missiles is more pressing, Army officials said developing better capabilities to detect biological warfare threats has also been a priority for the past six years. The Joint Program Executive Office for Chemical and Biological Defense is working with APG’s Edgewood Chemical Biological Center on the program, which is called the Joint United States Forces Korea Portal and Integrated Threat Recognition, or JUPITR. The program will also serve to detect naturally occurring biological threats. A key part of the program is the Kraken, which Army officials described as ‘a massive, multifunctional, all-seeing sensor suite designed to rapidly establish a defensive perimeter.'”

Funding Issues Stymie Pandemic Preparation

Collaboration between the biotech industry and the US government has been notoriously difficult, starting with the threat of breaking Bayer’s patent on Cipro during the Amerithrax attacks and continuing into today. While relations have improved, and the hurdles to a successful working relationship are significant, we can’t afford to not work on this.

Genetic Engingeering and Biotechnology News – “Despite product success Acambis has had a bumpy ride with its funding. ‘Any biotech that believes developing products to serve public health emergencies is access to easy money needs to think again,’ Dr. Lewin cautioned. ‘Collaborating with the U.S. government is different from working in the biotech world. You have to produce a proposal for the government to digest, a cost of around $400,000, and if you don’t get the contract that’s all money down the drain.'”

Scientists race to gauge pandemic risk of new bird flu

We’re keeping a very close eye on news about the H7N9 avian flu strain emerging from China. To date there have been fourteen cases with five fatalities.   Unlike the H5N1 strain of avian influenza, this is the first time we’re seeing H7N9 in humans. It’s pandemic potential is still considered low due to its current inability to transmit person-to-person. However, although there have been no confirmed cases of person-to-person transmission, it’s been reported that a person caring for one of the people who died of H7N9 has since developed similar, flu-like symptoms.

Reuters – “Genetic sequence data on a deadly strain of bird flu previously unknown in people show the virus has already acquired some mutations that might make it more likely to cause a human pandemic, scientists say. But there is no evidence so far that the H7N9 flu – now known to have infected nine people in China, killing three – is spreading from person to person, and there is still a chance it might peter out and never fully mutate into a human form of flu.”

Ten years after SARS, what has China learned?

The short answer? It depends on whom you ask. China has improved its communication with the international and scientific community. However, there have been complaints about the lack of clear communication by the Chinese government with its own people, particularly at the time of the virus’ original emergence.

Xinhua – “The news of two men dying from a new variant of bird flu has reminded Chinese of the SARS pandemic that hit the country one decade ago. Many are wondering if the government will handle the situation any better than it did in 2003, should another pandemic break out…Now, on the 10th anniversary of the pandemic, fear is spreading following reports of two Shanghai men who died from H7N9 avian influenza, a strain that has not previously been detected in humans. That fear was aggravated this week after four more patients in neighboring Jiangsu Province were confirmed to have contracted the virus. All four are in critical condition.”

Cambodia reports 10th bird flu case this year

In all the chatter about H7N9, H5N1 seems almost tame. While it may seem high, ten cases in four months is in keeping with expected numbers.

Xinhua – “A six-year-old boy from Southwestern Kampot province was confirmed to have contracted with Avian Influenza H5N1, bringing the number of the cases to 10 and the death toll remained at eight in 2013, a health expert said Wednesday. ‘The boy was admitted to the Kantha Bopha Hospital in Phnom Penh on March 31 for severe pneumonia, and he was tested positive for H5N1 at the Instituts Pasteur on Tuesday,’ Dr. Denis Laurent, deputy director of the hospital, told Xinhua.’The boy is still alive, but in severe conditions (sic).”

UN general assembly passes first global arms treaty

Including everything from battle tanks to light weapons, this is the first UN treaty “aimed at controlling the trade in conventional weapons”, and prohibits the sale of conventional weapons to state in violation of arms embargoes, in support of terrorism, war crimes, genocide, or in use against civilians (it doesn’t regulate domestic sales of arms).

The Guardian – “The United Nations…vot[ed] it through by a large majority despite earlier being blocked by three countries. Member states represented in the UN general assembly voted by 154 to three, with 23 abstentions, to control a trade worth an estimated £46bn a year. The landmark deal went to a vote after Syria, Iran and North Korea – all at odds with the US – blocked its adoption by consensus….It is expected to come into force after the first 50 ratifications next year”

Clinical Notes: Bird Flu Vaccine Delayed at FDA

It’s been an avian-themed report. This piece included in commiseration with of all of us just now getting around to taxes – filing paperwork appropriately with the government is apparently as important for billion-dollar corporations as it is for the rest of us.

MedPage – “GlaxoSmithKline’s (GSK) human vaccine against H5N1 avian influenza did not win approval from the FDA, but only on technical grounds that should not keep it off the market for long, the company said. Called Q-Pan H5N1, the product is meant to be stockpiled in case the H5N1 virus becomes capable of causing a pandemic. It received a unanimous endorsement from an FDA advisory committee last November. Nevertheless, GSK said last week that it had received a so-called complete response letter from the agency, indicating that approval was not immediately forthcoming. The company said it was ‘triggered due to an administrative matter that has recently been rectified.'”

Soapbox we love: Let’s All Stop Saying ‘Weapons of Mass Destruction’ Forever

The title says it all. It was arguably too broad when it was just chemical, biological, radiological (mass destruction? a rad bomb? really?) and nuclear, and it seems to only be getting broader.

Wired – “In fact, as a fascinating paper by W. Seth Carus at the National Defense University shows, the Defense Department’s definition of the term has long been problematic. For years, its official definition included ‘high explosives,’ to make it consistent with the federal statute that Harroun ran up against. But ‘most military weaponry relies on high explosive charges,” Carus writes, ‘meaning that even the mortars and grenades used by infantrymen might qualify as WMD.’ The doctrinal answer was ultimately to limit the definition to “chemical, biological, radiological and nuclear weapons capable of a high order of destruction or causing mass casualties.”

H5N1 viral-engineering dangers will not go away

Technically we tweeted this story on Wednesday, but it presented such a nice summation against the gain-of-function research that we wanted to include it here. Not because we agree, but because the points are coherent and well-argued.

Nature – “Rather than use the avian flu moratorium to seek advice, listen and foster debate, many influenza scientists engaged in an academic exercise of self-justification. There was a single large open meeting, at the Royal Society in London, which engaged a wider audience, including bioethicists. The recent calling off of the moratorium by 40 flu researchers alone — not funders, governments or international bodies — says it all. The flu community simply hasn’t understood that this is a hot-button issue that will not go away.”

Texas Biolab Loses Deadly Virus

Before everyone freaks out, it’s only Guanarito virus – yes, losing a vial of any virus from a BSL-4 lab is not great, and yes, if you’re going to lose a vial of something, it would be better if it didn’t cause hemorrhagic fever, but 1) Guanarito virus’ natural host is thought to be  Venezuelan “short-tailed cane” mice, 2) it doesn’t replicate in US rodents, and 3) it’s not transmissible person-to-person.  And before we start a heated discussion about the disturbingly impressive ability of viruses to evolve and adapt to new hosts, 4) the vial in question is thought to have been destroyed internally.

ABC News – “The Galveston National Laboratory lost one of five vials containing a deadly Venezuelan virus, according to the University of Texas Medical Branch, which owns the $174 million facility designed with the strictest security measures to hold the deadliest viruses in the country. Like Ebola, the missing Guanarito virus causes hemorrhagic fever, an illness named for “bleeding under the skin, in internal organs or from body orifices like the mouth, eyes, or ears,” according to the Centers for Disease Control and Prevention.”

UK: Biological attacks ‘getting easier for terrorists’

Intelligence officials in the United Kingdom have prioritized the fight against bioterrorism, using lessons from the 2012 London Olympics to inform their revamped strategy.

The Telegraph – “Charles Farr, the Director of the Office for Security and Counter-Terrorism [in the United Kingdom], said that extremists have ever greater access to the information and technology required to create and spread germ agents or other biological weapons…Factors facilitating such attacks include the availability of formulae and other information on the internet; increasing teaching of biological sciences at universities, and ‘greater availability of technology,’ he said. Mr Farr, a former MI6 officer, declined to give further details of the threat, but the Home Office report hints at a range of new precautions.

Scientists develop new foot and mouth vaccine

Foot-and-mouth disease is like the be-all-end-all of animal diseases – it’s tremendously infectious, has a high mortality rate, and because we don’t vaccinate (for trade reasons – when you vaccinate an animal, when that animal is later tested for FMD it’s impossible to tell whether it has the antibodies because it was vaccinated or because it actually had the disease – if the latter, no one wants to eat it), the disease would spread like wildfire. Also, current policy dictates “containment” (read: mass culling) rather than “treatment”, which means mountains of burning carcasses. Very scary and very possible.

The Guardian – “Scientists have developed a new kind of vaccine that could prevent devastating outbreaks of foot and mouth disease among livestock. The “synthetic” vaccine was created by taking protein shells that encase the virus and strengthening them, so the vaccine can be used in warm countries without refrigeration. The technique overcomes major shortcomings of existing foot and mouth vaccines, which are made with live virus. The infectious risk means the conventional vaccine must be produced in high containment facilities, which are costly to build and maintain. Vaccines made from the live virus are also fragile, and degrade unless they are kept cool.”

Study Shows Bacteria Moves From Animals to Humans

Bessie the cow might just be another weapon in the arsenal of the superbug. This possibility is especially disturbing given our ongoing difficulties countering antibiotic-resistant bacteria we make ourselves.

The New York Times – “A new study used genetic sequencing to establish that a strain of antibiotic-resistant bacteria has been transmitted from farm animals to people, a connection that the food industry has long disputed. Representative Louise M. Slaughter, Democrat of New York, said the study by researchers in Britain and Denmark, which drew on data from two small farms in Denmark, ‘ends any debate’ about whether giving antibiotics to livestock is a risk to humans”

LOCAL: Mumps virus infiltrates Richmond, VA campus

Before this launches a debate about the importance of vaccination, all but just six students on the Richmond campus have had  the MMR vaccine. What this illustrates instead is that no vaccine is 100% efficacious in every instance (MMR is approximately 95%).

The Collegian – “As of Tuesday, 15 cases of mumps have been confirmed on campus, said Dr. Lynne Deane, the director of the Student Health Center. Mumps is a communicable viral illness and typically carries symptoms like fever, head and body aches, tiredness and swollen or tender glands in the jaw, according to the Virginia Department of Health (VDH) Web site.Tests administered to other students are still being processed, she said. In total, 39 students have been tested for the virus since January, Deane said…The cluster of mumps outbreaks has not been limited to Richmond. Loyola University, Maryland, has seen at least 12 cases of mumps arise in the past month, according to CBS news Baltimore.”
