Welcome to World Antibiotic Awareness Week! We all have a part in reducing microbial resistance, including companies like McDonalds, KFC, and large chain restaurants. A recent report from Clinical Microbiology is reanalyzing the threat of bioterrorism. The EU has released their action plan for combatting antimicrobial resistance and you can read the roadmap here. Leishmaniasis infections are on the rise in the U.S. due to ecotourism and military campaigns in Iraq and Afghanistan. CRISPR gene-editing was just tested in a person for the first time. The Chinese research group delivered modified cells into a patient with aggressive lung cancer as part of a clinical trial. The cells were modified to disable a gene that codes for protein PD-1 (this normally would restrict immune response and is frequently manipulated by cancer) and the hope is that without the PD-1, the edited cells will be able to overcome the cancer.

ISIS Forces Fired Toxic Chemicals in Iraq
Three chemical attacks were launched by ISIS against the Iraqi town of Qayyarah in September and October. The use of chemical weapons was in retaliation after Iraqi government forces retook the town in late August. “ISIS attacks using toxic chemicals show a brutal disregard for human life and the laws of war,” said Lama Fakih, deputy Middle East director. “As ISIS fighters flee, they have been repeatedly attacking and endangering the civilians they left behind, increasing concerns for residents of Mosul and other contested areas.” Victims of the attacks experienced painful symptoms of blister agents, or “vesicants”. The use of chemical weapons is in direct violation of the 1993 Chemical Weapons Convention. The use of these weapons would be classified, under the Rome Statue, as a war crime.

What Will Be the Next Pandemic?
Researchers at the recent International Meeting on Emerging Diseases and Surveillance discussed what the next SARS or Zika-like disease will be. Kevin Olival of EcoHealth used a predictive formula and pointed to flaviviruses that we normally don’t hear about – Usutu, Ilheus, and Louping. “All three have on rare occasions infected people, but they also infect a number of other animal species, which suggests they may have what it takes to jump species. Virologists sometimes call viruses that can do this ‘promiscuous.’ That means ‘it’s more flexible in its ability to infect across hosts, including mammals,’ Olival said.” While the scarcity of human cases proves difficult for gaining funding, emerging diseases tend to hit us by surprise, pointing to the need to expand the scope of surveillance and preparedness.

PCAST Letter to the President to Protect Against Biological Attacks
In a letter to the President, the President’s Council of Advisors on Science and Technology (PCAST) points to the to the unique challenge of bioterrorism threats in that they could be exacerbated by the rapid pace of biological science and technology developments. PCAST emphasizes the need for a renewed effort since Federal leadership can help state and local infrastructure share data and identify patterns during such an event. “Continuing scientific, technical, and regulatory developments allow the medical community to respond to new outbreaks faster than ever before. Developing medical countermeasures to naturally occurring outbreaks today lays the groundwork for responding to potential engineered biological threats in the future. PCAST supports extending this progress into the foreseeable future, setting the ambitious ten-year goal that, for infectious organisms for which effective approaches to creating vaccines exist, the United States should have the ability to accomplish, within a six-month period, the complete development, manufacture, clinical testing, and licensure of a vaccine. ”

Comic Book Explores a World Without Antibiotics  screen-shot-2016-11-15-at-8-40-41-am
A new, dystopian comic book is transporting us to 2036 London. The world is a bleak place where antibiotics have run out. Surgeon X looks at a time where simple infections and hospitalization means certain death, while the government cracks down to maintain selective control over the few drugs that are available via  a”Productivity Contribution Index”, which determines who gets access to medication. Readers follow a surgeon, Rosa, through her work at a secret clinic and the internal dialogue that comes with a repressive government, Hippocratic oath, and constant threat of infectious disease. Sara Kenney, the author of Surgeon X, notes that her own experiences with two premature children frame much of her comments on microbial resistance. Kenney noted that “it was only when she started building for herself what she calls the ‘story world’ that she realized antibiotic resistance is such a threat to medicine that it needed to be in her narrative as the obstacle the protagonist must overcome. ‘I realized the antibiotics crisis we’re facing is probably one of the most extreme obstacles you could throw at a surgeon,’. She found the complexities of the problem—resistance is believed to kill 700,000 people around the world each year—to be staggering.”

WHO Global Action Plan on Antimicrobial Resistance cxt8sslxgaajprd-jpg-large
The WHO has just released their action plan to fight antimicrobial resistance. Countries have committed to having a national action plan by May of 2017 to better support the radical shift that is needed to combat antibiotic resistance. Antimicrobial resistance (AMR) threatens the foundation of modern medicine and public health capacity. There have been little advancements in the world of antibiotics, however we continue to see a growth of AMR. The WHO global action plan has five objectives: to improve awareness and understanding of antimicrobial resistance through effective communication, education and training; to strengthen the knowledge and evidence base through surveillance and research; to reduce the incidence of infection through effective sanitation, hygiene and infection prevention measures; to optimize the use of antimicrobial medicines in human and animal health; and to develop the economic case for sustainable investment that takes account of the needs of all countries and to increase investment in new medicines, diagnostic tools, vaccines and other interventions.

BWC RevCon 
While the 8th Review Conference is underway, there have been some reports from attendants that civil society/NGO’s were asked to leave the room, which goes against precedent for the last two RevCon’s. Some have noted that Iran was seeking to deny NGO’s access to Committee of Whole by using rules of procedure but there has not been consensus yet. While these comments have been coming in from attendants’ Twitter accounts, as of Tuesday afternoon, it appears that the issue has been resolved – as news continues to trickle in, we’ll keep you posted. You can get daily updates on RevCon here, with the most recent one covering the cross-cutting plenaries that are focusing on implementation, article III, solemn declaration and more. These daily reports are the best way to get detailed play-by-play information as to how RevCon is going.

Zika Updates
A recent study found that women are at greater risk for Zika infections due to suppressed vaginal immune response. “Scientists at the Gladstone Institutes discovered that the vaginal immune system is suppressed in response to RNA viruses, such as Zika. The delayed antiviral immune response allows the virus to remain undetected in the vagina, which can increase the risk of fetal infection during pregnancy.” The Brazilian state of Parana has banned aerial spraying of pesticides in urban areas. Florida’s Department of Healthy has their daily Zika updates here, which shows three new locally acquired cases as of 11/16. The CDC has reported 4,255 cases in the U.S. as of November 16, 2016.

Stories You May Have Missed:

  • How NY Hunts for Early Hints of an Outbreak– the New York City Department of Health and Mental Hygiene has a secret weapon in the war against infectious disease outbreaks – a computer program called SaTScan.  This program utilizes big data to help detect and model infectious diseases. It monitors, maps, and detects disease outbreaks throughout the state by utilizing the data that is reported to the health department daily. “It is just not possible to effectively monitor every communicable disease in real time with human eyes alone,” Sharon Greene said. “To be able to quickly and effectively and precisely detect an outbreak, to kick off an outbreak investigation process — the earlier that you can begin this it helps to limit sickness, it helps to limit death, and it makes it more likely that you will successfully solve the outbreak.”
  • Exposure Patterns in 2014 Ebola Transmission – Researchers are presenting new information regarding the largest Ebola outbreak in history by looking at the drivers of transmission and where control efforts could be strengthened. They reviewed data from over 19,000 cases across Guinea, Liberia, and Sierra Leone. “We found a positive correlation (r = 0.35, p < 0.001) between this proportion in a given district for a given month and the within-district transmission intensity, quantified by the estimated reproduction number (R). We also found a negative correlation (r = −0.37, p < 0.001) between R and the district proportion of hospitalised cases admitted within ≤4 days of symptom onset. These two proportions were not correlated, suggesting that reduced funeral attendance and faster hospitalisation independently influenced local transmission intensity. We were able to identify 14% of potential source contacts as cases in the case line-list. Linking cases to the contacts who potentially infected them provided information on the transmission network. This revealed a high degree of heterogeneity in inferred transmissions, with only 20% of cases accounting for at least 73% of new infections, a phenomenon often called super-spreading.” Future Ebola outbreak response will need to consider super spreaders, safe funeral practices, and rapid hospitalization.
  • Rick Bright Selected as New BARDA Director – DHHS recently announced that Dr. Rick Bright will be the new Deputy Assistant Secretary for Preparedness and Response and Director of BARDA. Dr. Bright has been with BARDA since 2010 and served in their Influenza and Emerging Infectious Diseases division.

 

Pandora Report 8.19.2016

The Olympics are winding down and now many are waiting with bated breath to see if those attending the games will bring back more than just memories to their home countries. A recent study revealed that people infected with Ebola were 20% more likely to survive if they were co-infected with malaria-causing Plasmodium parasites.  Yellow fever continues to burn through the DRC and many are wondering if it could become the next pandemic as it’s on the brink of spreading to Europe and the Americas.  The UN has finally acknowledged the role it played in the cholera epidemic that hit Haiti following the devastating earthquake six years ago. The UN acknowledgement comes after years of cited reports and public outrage regarding the importation of the disease as a result of UN peacekeepers. China has reported several cases of human infection with avian influenza (H7N9). While human-to-human transmission has not occurred, it can’t be ruled out.

From Anthrax to Zika – We’ve Got You Covered 

We’re always on the lookout for new pieces written on biowarfare and this week brought some gems to the table. Get the scoop on Russia’s old anthrax bioweapons program and how genomic sequencing revealed more details into both the program and the “biological Chernobyl” that was Sverdlovsk. Researchers like Paul Keim, Matthew Meselson, and Jeanne Guillemin, have been looking to unravel the outbreak in Sverdlovsk and that it wasn’t “unreasonable to suspect that the Soviets would have tried to create a superstrain” of the disease. Interestingly, “the team didn’t see any evidence that Soviet engineers had tried to grow a strain that was resistant to drugs or vaccines, or that they had genetically engineered the bacteria in any way” and there were actually few changes within the genome. You can read more about the genome sequence from the Sverdlovsk 1976 autopsy specimens here.  The good news is that through Keim’s work, it is possible to review anthrax genome sequences from any future outbreaks and determine if it is some leftover Soviet weapon strain or another source. The CDC recently published an overview of biological warfare in the 17th century within the Emerging Infectious Diseases journal. You can venture through time to look at the siege of Candia during the Venetian-Ottoman War of the 17th century. “Plague was first detected in Reval on August 10, 1710, while the army from Russia was still approaching the city. Reval was not besieged, and the Russians merely camped outside the city while attempting to isolate it. The army dumped corpses into a stream that flowed into Reval, but evidence does not show that the dead were plague victims, nor does evidence exist that clarifies whether the intent was contamination of the water supply or disposal of bodies. Original accounts provide no evidence to suggest that Russians hurled bodies into the city, much less plague-infected bodies.”

ISIS’ Chemical Weapon Use: A Serious Threat On The Rise

Senior DoD consultant, Zamawang Almemar is discussing the rising threat of chemical weapons and why the “international community must respond aggressively to this threat and prevent ISIS’ ability to access chemical raw materials and transform them into weapons.” The recent chemical attacks on Kurdish civilians aren’t the first and probably won’t be the last. From President Saddam Hussein to ISIS, the threat of chemical weapons and use of mustard gas (sulfur mustard) has been a consistent tool in warfare. Almemar points to the psychological impact of chemical weapons use against the Peshmerga and that ISIS also employs these tactics to benefit from the lack of protective gear and preparedness within the Kurdish military and civilians. “The Kurdish Peshmerga forces undoubtedly continue to win the war against ISIS with conventional weapons on the battlefield and with help from the U.S. and coalition forces. However, when it comes to unconventional weapons, such as chemical weapons, they are lacking even the most basic protective equipment”. Given the consistent use of these weapons, now is the time for the international community to help supply basic protective gear for both Peshmerga forces and Kurdish civilians, to help prepare and defend against ISIS chemical weapons attacks.

Does the U.S. Need a Rapid-Response Fund for Infectious Diseases?

Greg Mercer talked about this a few weeks back, but I think we can all safely say the answer to this question is a rather enthusiastic “YES”. The Congressional standoff with Zika funds has brought the role of federal emergency funds into the limelight. The good news is that it sounds like lawmakers have learned from this situation and it’s sounding more and more like the next health spending bill will emphasize the creation of a reserve fund for the CDC to use in the next public health crisis. “The House version of the bill, which would fund the federal health agencies for the fiscal year that starts in October, has a $300 million “rapid response reserve fund” for infectious diseases. It’s a smaller version of an idea that Democratic lawmakers and current and former Obama administration officials have been promoting for months, ever since it became clear that Congress was incapable of anything close to a rapid response to Zika.” While there’s no guarantee and it will require the spending bill to be completed before President Obama leaves office, it’s a step in the right direction. The question now becomes, is this enough? Many are pointing out that while this is a great start, $300 million is simply not enough and the fund needs to be labeled as an emergency fund, not a rapid response reserve. CDC Director Tom Friden as been fighting the funding battle for over six months now, pointing to the rising case counts and growing presence of local transmission. “If you were going to do something like create a vaccine, $300 million would be entirely used up by that,” Frieden said. “If you were going to do something like a rapid response while you kind of assessed the disaster … that obviously is enough to get started. It’s not going to provide all of the funding, but it would allow you not to be so stuck.”

Report Details DoD Chem/Bio Defense Programs 

The DoD 2016 report to Congress was released recently, describing the research and development practices that have used to combat chemical and biological threats. In fact, the DoD’s Chemical and Biological Defense Program (CBDP) has provided funding for the new plague drug that was recently approved as a medical countermeasure. “The DoD faces CB threats that are complex, diverse, and pose enduring risks to the Joint Force and Homeland,” the new report said. The variety, origin, and severity of these threats continues to grow while resources shrink. DoD said it performed basic research in genetic engineering and nanoelectromechanical systems related to defense against CB threats, and supported the response to the Ebola outbreak in West Africa, among other initiatives.” Despite their work and progress, there are still challenges when it comes to biosafety, which were noted in regards to the shipping of live anthrax spores from a DoD lab. Budget reductions are expected to translate into a decrease in ChemBio defense research funding, which makes the job of combatting an increasingly complex threat that much more difficult. As the report notes, “this environment translates into increasingly complex program management decisions with no margins for error due to a lack of sufficient and predictable resources.” As Almemar previously noted, the recent use of chlorine gas by Syrian government forces and the ongoing use of chemical weapons by ISIS all point to the imperative need for continued support and funding for chemical weapon defense.

BARDA Medical Counter Measures Industry Day

The Biomedical Advanced Research and Development Authority (BARDA) and the Office of Acquisitions Management Contracts and Grants (AMCG) will be hosting their annual conference to provide a better understanding about federal medical countermeasure requirements. The October 18-20th event in Washington, DC, will allow participants to interact with BARDA and AMCG staff, and network with private sector colleagues. During the conference, participants will also learn about BARDA’s strategies and goals for FY2017 and beyond, challenges of dealing with emergency, as well as current, infectious diseases, new initiatives, and roles and responsibilities of BARDA, AMCG, and private sector partners.

Zika Virus – Emergency State of Affairs

The CDC has declared a public state of emergency in Puerto Rico over Zika virus. Last week saw over 1,900 new cases reported in Puerto Rico, which brings the total case count to over 10,690. Concerns are growing after the massive flooding in Louisiana and the potential risk for increased Zika virus transmission. While flood water may wash away eggs, the risk for containers and abandoned housing as a breeding ground for mosquitoes may support further transmission. Forbes has posted the winners and losers of $81 million in Zika funding here. What are the legal implications of employee-related Zika virus infections? Legal teams around the U.S. are starting to gear up for the potential legal ramifications and how employers and/or employees will respond to infections. Check out this personal account of a patient infected with Zika, who experienced the challenges of getting medical care in the U.S.  As of August 17th, the CDC has reported 2,260 cases within the U.S. You can find a timeline of the spread of Zika here.

    Following Russia’s frozen anthrax problem, many are worried that something much more sinister, like smallpox, could be found in the permafrost. Siberia, like the rest of the world, dealt with smallpox outbreaks in the 19th century. One particular outbreak was in a town that saw 40% of the population die and resulted in the rapid burial under the permafrost soil. With the eroding river banks and disappearing permafrost, time will tell if there are more zombie microbes awaiting their rise from the permafrost grave.

While humans can acquire H3N2 from close contact with infected pigs, the illness is considered mild in humans.

Pandora Report 5.27.2016

Before you start your holiday weekend, what’re your thoughts on Usain Bolt outrunning a mosquito? The Jamaican sprinter jokingly responded to questions regarding athlete concerns over Zika virus, noting that he’s not worried “because I’m fast – they can’t catch me”. (Hint – it looks like he can outrun a mosquito with his 22 mph capabilities versus the 1.12-3.35 mph of an Aedes mosquito). Sticking with the Olympian theme..bacterial teams? Researchers recently found that two strains of E.coli, resistant to different antibiotics, can protect each other in an environment containing both antibiotics. The phenomenon is called mutualism and researchers at MIT are now looking looking into the range of this practice and the potential for population synchronization. At the 69th World Health Assembly this week, the WHO revealed plans to revamp itself however, many point out that for an agency better at giving advice than taking action, it’s too little too late. In the case of the WHO, critics are calling for acta non verba. 

The World Bank Rolls Out the Pandemic Insurance Plan
Following the Ebola outbreak in West Africa, the World Bank has announced a new program that will enable funds to rapidly be mobilized during outbreaks. In hopes of ensuring a more speedy response to infectious disease disasters, World Bank President Jim Yong Kim stated that “pandemics pose a serious threat to global health and economic security.” The new Pandemic Emergency Financing Facility (PEF) is “a combination of catastrophe insurance and bonds, is a direct reaction to the sluggish donor response to the outbreak of Ebola”. Presented at the G7 meeting for finance advisors, Japan has already committed support with a $50 million contribution. The insurance will cover several classes of infectious disease outbreaks most likely to cause epidemics – ranging from new influenza or coronavirus strains, filoviruses like Marburg and Ebola, and other zoonotic diseases. The initial plan is to have a total of $500 million  and hopefully avoid outbreaks, like Ebola, rapidly growing due to poor financial support and response.

Antibiotic Apocalypse
As much as I’d love to say this title is a dramatic take on the issue of antibiotic resistance, the truth is pretty startling. A report done by the Review on Antimicrobial Resistance  (commissioned by the UK government and reviewed by officials including economist Jim O’Neill), estimated that by 2050, 10 million lives per year and $100 trillion are at risk due to drug-resistant infections. That’s quite a stark estimate, but as many have pointed out “the problem of drug-resistant microbes isn’t just about biology and chemistry; it’s an economic problem at heart, a catastrophic and long-bubbling mismatch between supply and demand. It’s the result of the many incentives for misusing our drugs, and the dearth of incentives for developing new ones.” Can we really tackle this issue though? It still amazes me hearing people in an emergency department or urgent care asking for an antibiotic and the physician having to explain that they have a viral infection or that antibiotics simply aren’t warranted. In many ways, when we are sick enough to go to the doctor, we want to walk away with some “cure” and the notion of bedrest and hydration isn’t all that comforting. So what can we do? The report notes some steps to help prevent this impending reality – massive global public awareness campaigns, improve hygiene, improve global surveillance of drug resistance and antimicrobial consumption in humans and animals, promote development and use of vaccines, promote new, rapid diagnostics to cut out the unnecessary use of antibiotics, better incentives to promote investment for new drugs and improve existing ones, improve the numbers, pay, and recognition of people working in infectious diseases (hear, hear!), etc. Other recommendations include improving sanitation and a global innovation fund for early-stage research. Scientists were recently startled to find for the first time in the U.S., a patient with a bacteria that is resistant to antibiotics that are used as a last resort. While the predictions are daunting, the threat of antibiotic resistance is one we can get ahead of if we make the commitment and start immediately.

The Growing Threat of Spillover Screen Shot 2016-05-23 at 9.38.18 AM
The United Nations Environmental Programme (UNEP) released their 2016 Frontiers Report “Emerging Issues of Environmental Concern”. One of the six major issues was zoonosis. “There is a worldwide increase in disease emergence and epidemics particularly from zoonoses – diseases that can be passed on between animals and humans. The report illustrates how the emergence and re-emergence of zoonotic diseases are closely interlinked with the health of ecosystems. The risk of disease emergence and amplification increases with the intensification of human activities surrounding and encroaching into natural habitats, enabling pathogens in wildlife reservoirs to spill over to livestock and humans.” The report notes that around 60% of all infectious diseases in humans are zoonotic and 75% of emerging infectious diseases are zoonotic. You can also find several great infographics that paint a very surprising picture regarding the emerging zoonotic disease events from 1940-2012 and the top three reported zoonoses for specific continents. The growing Zika epidemic is just another in a long list of spillover cases including those of MERS, SARS, Ebola, and Rift Valley fever.

A Need To Rebalance
GMU Biodefense professor and Program Director, Dr. Gregory Koblentz, is pointing to the need for the U.S. to refocus its nonproliferation efforts on South Asia. Given the region’s high risk for nuclear crisis as a result of territorial disputes, cross-border terrorism, and increasing nuclear arsenals, there is a crucial need to re-allign nonproliferation efforts to include South Asia. “As of 2015, India was estimated to have 120 nuclear warheads while Pakistan was believed to possess 130 weapons. Both countries have also continued to develop, test, and deploy new missiles designed to deliver nuclear warheads. Pakistan has tested seven different types of nuclear-capable ballistic and cruise missiles, including the 2,750-kilometer range Shaheen-3 ballistic missile. Meanwhile, India has tested nine different types of nuclear-capable missiles, including the Agni-V intercontinental ballistic missile with a range of over 5,000 kilometers.” Dr Koblentz points to the impacting introduction of tactical nuclear weapons in South Asia and their ability to be deployed on short-notice – also concerning is India’s planned development of strategic missile submarines, which will likely trigger development from Pakistan. He notes that the international community can help restrain this dangerous competition by encouraging both countries to adopt confidence-building measures (limits on development of tactical nuclear weapons, etc.) and engage in high-level talks with “other nuclear weapon states to discuss measures that could further reduce the risk of nuclear weapons being used deliberately, by accident, or in an unauthorized manner.”

Rebuilding Trust in Biology 
Between the gain-of-function talks and biosecurity failures at major U.S. labs, there’s been a subtle shifting in the trust and support for biological sciences. New regulations could change oversight for sciences within the U.S. and many are wondering how we can restore trust back into this field. While we can all agree that forgotten smallpox vials and an accidental bird flu release translates to a need to revamp practices and facilitate more effective and efficient oversight, there’s been little mention of how we can combat the trust issues. This week the National Science Advisory Board for Biosecurity (NSABB) met to conclude their 18-month deliberation on select pathogen research practices and regulations. Let’s hope that with more effective and efficient practice recommendations, they are also looking into repairing the reputation of science and biology. Dr. Filippa Lentzos and Dr. Nicholas Evans recommend four ways to rebuilt this trust- transparency in process and outcome of experiments and review, life scientists need to play their part in monitoring and preventing deliberate misuse of biology, accountability needs to be built into scientific norms, and decisions on pursuing dangerous experiments need more transparency in regards to their process. “There should also be clear, internationally-recognized red lines about the sorts of experiments—such as attempting to make Ebola virus transmit like the flu, or modifying an extinct virus like smallpox—that simply should not be done.”

Energy & Commerce Subcommittee Looks at U.S. Biological Threat Preparedness
The Energy and Commerce Subcommittee on Health held a hearing regarding H.R. 3299, Strengthening Public Health Response Act, last week to discuss and review legislation that would enable the U.S. to prepare and defend against biological attacks. The act was presented in response to the October 2015 Blue Ribbon Study on Biodefense that highlighted the general lack of preparedness against emerging biological threats. “Thirty-three recommendations to improve the U.S. response to biological threats were made by the Blue Ribbon Study on Biodefense, which was led by former U.S. Sen. Joe Lieberman (I-CT) and former Pennsylvania Gov. Tom Ridge, the first Secretary of Homeland Security. The panel’s report was based on meetings, interviews and research.” Acting Biomedical Advanced Research and Development Authority (BARDA) Director Dr. Richard Hackett noted that “the array of threats for which we must be prepared is vast. Such threats include bioterrorist agents such as anthrax, smallpox and botulism; evolving and emerging threats causing substantial regional disruption such as Ebola and Zika; and highly communicable diseases with pandemic potential such as influenza.” This act would also expand the Priority Review Voucher program within DHS and work to facilitate BARDA’s partnership with the private sector.

Weekly Zika Updates
On Monday, WHO Director-General Dr. Margaret Chan pointed to the failure to maintain mosquito-control efforts and the spread of Zika. “Let me give you a stern warning. What we are seeing now looks more and more like a dramatic resurgence of the threat from emerging and re-emerging infectious diseases. The world is not prepared to cope. Above all, the spread of Zika, the resurgence of dengue, and the emerging threat from chikungunya are the price being paid for a massive policy failure that dropped the ball on mosquito control in the 1970s,”. The European Centre for Disease Control and Prevention (ECDC) released a risk assessment for European travelers to the Olympic Games, finding that they’re most at risk for gastrointestinal illness and vector-borne diseases. Researchers are also considering the association between Zika virus and eye problems in babies that have microcephaly. During your holiday weekend, take a minute to learn about the Scottish professor who discovered Zika virus. Experts are also pointing to the role of misinformation (via social media conspiracy theories) in prevention efforts.  “The researchers behind the study—from Johns Hopkins University, George Washington University, and the University of Georgia—say the misinformation they detected by analyzing thousands of Twitter posts could cause many vulnerable people to refuse future Zika vaccinations.” The CDC has estimated that a fetus infected with Zika virus during the first trimester has a 1-13% risk of developing microcephaly. As of May 25th, the CDC has reported 591 travel-associated and 11 sexually transmitted cases in the U.S.

  • Why Victorian Diseases Are Making a Comeback – Scarlet fever and TB have been on the rise in the UK and many are pointing to the growing threat of antibiotic resistance and poor vaccination compliance. Many of these diseases have been under control for centuries so any uptake can cause a sensational public response, however it’s important to remember the recent plethora of measles outbreaks and just how vital vaccination is. Antibiotic resistance alone could bring back these diseases and take us back to a time where infectious diseases were the major cause of death.
  • The Threat of Agroterrorism and Zoonotic Disease in the U.S. –  Gary Flory, Agricultural Program Manager of the Virginia Department of Environmental Quality, discusses the threat of these diseases for the Non Conventional Threat CBRNe Meeting. “The threat of agroterrorism and naturally occurring disease outbreaks in the United States continues to expand as new diseases emerge and existing diseases become endemic in many parts of the world. The food and agricultural sector is one of the easiest sectors of any nation’s economy to disrupt and its disruption could have catastrophic consequences both nationally and regionally. Both developing and developed countries will be impacted by a disease outbreak or agroterrorism attack.”

It’s been quite a week for global health security. Even the X-Files covered worldwide pandemics (that’s right, multiple diseases), CRISPR-Cas9, and military vaccination programs. Measles is hitting Nigeria hard as Lagos state officials announced the deaths of 20 children related to the outbreak. A recent study released by the University of Pennsylvania’s Annenberg Public Policy Center found that more than one third of participants believed Zika virus was a conspiracy theory related to genetically modified mosquitoes. Maybe they were also watching the X-Files? Before we begin, meningitis vaccine efforts were celebrated at the Meningitis Vaccine Project (MVP) conference, due to success within Africa’s meningitis belt.

GMU Biodefense Course Sampler- “Biosecurity as a Wicked Problem”
If you’re on the fence about going back to school, curious about our program, or just want to hear what a class in biodefense would be like, check out our course sampler on Wednesday, March 2nd, at 7pm, in our Arlington Campus in Founders Hall, Room 502. “The United States and the world face unprecedented threats to global biosecurity, including emerging infectious diseases, pandemics, natural disasters, bioterrorism, and laboratory accidents. Find out about the challenges posed by these threats and strategies for enhancing global health security.” How many times can you sample a course from not only an expert in the field, but also the director of the program? Dr. Koblentz will be your host for this evening lecture on biodefense, dual-use research, CRISPR-Cas9, biosecurity, and much more. Can’t attend in person? Don’t worry – we’re also live-streaming here. Come join us for a look behind the curtain of not only our GMU graduate programs, but also the world of global health security.

CRISPR and The Battle of Genetically Modified Mosquitoes 
CRISPR-Cas9 technology has been a hot topic since it was discovered and things have only ramped up since a Chinese research team announced last Spring that they successfully edited human embryo genes. While many raised concerns over “designer babies” and genetically modified livestock, the case for genetically modified mosquitoes has also been discussed. What if science could modify mosquito capabilities to carry disease? CRISPR-Cas9 research is getting much closer to making this a reality with the help of two research teams. “The first group, led by Valentino Gantz and Ethan Bier at the University of California–San Diego, and Anthony James at the University of California–Irvine, engineered a gene drive carrying a pair of genes designed to kill the malaria parasite inside the mosquito.The second group, led by Nikolai Windbichler, Andrea Cristanti, and Tony Nolan at the Imperial College London, developed a more brute force approach, building a gene drive that breaks an important mosquito gene and renders the females sterile—a strategy designed to decimate a mosquito population. Both groups reported that, when the genetically modified insects were crossed with wild ones, as much as 99 percent of the offspring carried the modified genes, a clear sign that the gene drives were working.” While field tests are still necessary to establish efficacy, it’s important to note the researchers are taking great strides to ensure public buy-in given the sensitivity of such work. Gene drive is becoming more accessible and the applications appear limitless however, ethical use of this pioneering innovation is crucial for future work.

Climate Change & Zika Virus – What’s the Link?
Somewhere between reporting on CRISPR-Cas9 mosquitoes and Zika updates, it seems like a perfect place to discuss what kind of impact climate change is having on infectious diseases…especially Zika virus. GMU Biodefense MS student and one of our contributors, Greg Mercer elaborates on the role climate change may have on the growing geographical distribution of mosquitoes that pose some of the biggest threats. Greg points out that “exactly how climate change drives the spread of Zika and other diseases is hard to define. In 2013, researchers at the University of Arizona published a paper examining the effect of climate factors on dengue and its Aedes vectors. Their conclusion highlighted just how far scientists still have to go in understanding the climate-disease link: ‘Climate influences dengue ecology by affecting vector dynamics, agent development, and mosquito/human interactions,’ they wrote, but ‘although these relationships are known, the impact climate change will have on transmission is unclear.’ Climate change introduces additional complications into an already complex system, the study authors explained: It’s difficult enough to understand how weather, climate, human interaction, or mosquito behavior contribute to the spread of a virus.” Researchers are now comparing the global distribution of Aedes mosquitoes and the spread of Zika, which leaves many to wonder if the threat of global disease will evolve with that of global climate change.

BARDA Seeks Advanced Public Health Consequence Modeling
The Biomedical Advanced Research and Development Authority (BARDA) is currently working to find partners that can aid in the development of a modeling system that would support federal decision makers in their planning and response to CBRN events. “The tools developed under this acquisition will assist Federal decision makers with medical and public health decision making for the advanced development and implementation of an integrated National medical countermeasures infrastructure (e.g., vaccines, therapeutics, diagnostics, and medical devices).” They’re hoping to build partnerships to establish a network for medical consequence modeling, simulation, visualization, and decision support. BARDA plans to include two functional areas within the network, 1- decision support, reach back, analysis, and modeling (DREAM), and 2- professional services and systems integration (PSSI). “These activities include assisting government decisions makers during the development of preparedness plans, the implementation of response strategies, and communications with a wide variety of stakeholders, both during day to day operations and in the course of declared public health emergencies as part of the BARDA Modeling Coordination Group.” Each functional area will have multiple Indefinite Delivery/Indefinite Quantity (IDIQ) awards that can be earned and they are encouraging interested stakeholders to submit proposals.

To Zika and Back

As Zika virus continues to spread and South Africa reports the first of their cases, many are wondering how these outbreaks tend to go from 0-60 in a hot minute. NIAID director, Anthony Fauci, discusses the reality of disease surveillance and revealed this slide during an interview, of which you can see the global examples of emerging and re-emerging infectious diseases. Dr. Fauci points to the unpredictable nature that is public health and global health security. Global public health is still reeling from the effects and imperfect response of Ebola 2014, coupled with the scrutiny of a response to H1N1 that was considered too zealous. I’ve always considered public health and disease prevention to be the kind of work where few realize when you’ve done your job correctly but when you fail, it’s something you’ll be hearing about for decades. Global health security is challenging on a good day and public health tends to get little funding, especially in the countries that need it most. After the devastation of Ebola and all the after-action reports, many are wondering how did we miss the rise of Zika virus? Dr. Ken Stuart, director of the Center for Infectious Disease Research in Seattle, says, “We were unaware of the severity of the disease … [and] were unaware this virus had the capability for getting distributed so rapidly.” Regarding the funding issues that often plague infectious disease efforts, he noted that “this really goes back to funding priorities. Much of the funding devoted to infectious disease today is in reaction to outbreaks. Therefore, we’re not generally prepared to respond quickly. In other cases there are diseases that are very rare but they have an advocacy group that generates research activities. In the case of diseases like Zika, which were isolated in remote areas of the world where that population had no resources or advocacy group, there was no push to do research.We’re not stuck with what we’ve got. There are conversations between federal funding agencies and private organizations to try to prioritize the utilization of their resources, and I would say the NIH has been a leader in supporting the fundamental research that actually, probably positions us best to be prepared to respond to these disease outbreaks.” In other Zika news, a CDC team just arrived in Brazil to study the associated birth defects and the White House is urging Congress to provide emergency funds to support Zika response efforts, rather than just re-directing funds from Ebola-related projects. You can also see a map tracing the spread of Zika and some background here. As of February 24, the CDC has reported 107 travel-associated cases in the U.S.

The Rise of Chikungunya
I always thought it sounded like the name of a monster and in some ways, that’s pretty spot on. The Pan American Health Organization (PAHO) reported 16,668 confirmed and suspected cases of Chikungunya in 2016 so far. Colombia shouldered the majority of 2016 disease burden, with a spike of 1,189 new cases added to their previous count of 5,752. The PAHO is still playing catch-up on their year-end reporting for 2015, but it looks like 28,722 additional infections were added to their 2015 data. These updates mean that this region experienced 726,478 cases in 2015, and with the the new cases reported as of February 19, this current outbreak has been responsible for 1.89 million infections. Starting in 2013, this outbreak began on St. Martin and has been gaining traction ever since. Hopefully with the mosquito-control efforts related to Zika virus, the mosquito population also responsible for Chikungunya will begin to decline.

  • Breaking Down the Barriers of MDRO’s:  Scientists in the UK have discovered how drug-resistant bacteria create and maintain their defensive wall. Using the Diamond Light Source machine to “investigate in tiny detail a class of bugs known as Gram-negative bacteria”, they were able to find a defensive wall and it’s assembly beta-barrel machinery (BAM). This new research means that future treatments can aim at preventing bacteria from building these defense measures versus just attempting to attack the bacteria itself.
  • Melbourne Measles Outbreak – 14 cases have already been confirmed in the suburb of Brunswick, of which 2 were children from a primary school. Students that attend the same school and are not fully immunized were instructed to stay home to avoid exposure.
  • E. coli Outbreak in Raw Milk – Not surprisingly, a recall has been issued related to unpasteurized raw milk from a local dairy farm in Fresno, CA. 10 people have been confirmed with Shiga-toxin producing E. coli 0157:H7. Thankfully the shelf-life of the product has passed and public health officials, while stating that the investigation is on going, have confirmed that no health alert was issued since the product is believed to no longer be within the marketplace. Moral of the story – avoid raw, unpasteurized milk.

Pandora Report 7.11.15

Sorry for the late update here at Pandora Report. We’ve got how the plague turned so deadly, an Ebola update, and of course other stories you may have missed.

Have a great week!

These Two Mutations Turned Not-so-Deadly Bacteria Into the Plague

Researchers at Northwestern University have been investigating how Yersinia pestis—the bacteria that causes bubonic, pneumonic, and septicemic plague—became the infective cause of the Black Death. They discovered two mutations that help to explain the bacteria’s lethality.

Smithsonian.com—“The first mutation gave the bacteria the ability to make a protein called Pla. Without Pla, Y. pestis couldn’t infect the lungs. The second mutation allowed the bacteria to enter deeper into the bodies, say through a bite, to infect blood and the lymphatic system. In other words, first the plague grew deadly, then it found a way to leap more easily from infected fleas or rodents to humans.

Ebola Strain Found on Teen in Liberia Genetically Similar to Viruses in Same Area Months Ago

I’m sure you’ve heard that there were three new cases of Ebola in Liberia—a country that was declared free of the disease on May 9. According to the World Health Organization, samples taken from a teenager who died from Ebola two weeks prior indicate that the disease is genetically similar to strains that infected people in the same area over six months ago—while the outbreak was still ongoing.

US News and World Report—“That finding by genetic sequencing suggests it is unlikely the virus was caught from travel to infected areas of Guinea or Sierra Leone, the group said. “It also makes it unlikely that this has been caused by a new emergence from a natural reservoir, such as a bat or other animal,” it said.”

The Pandora Report 10.25.13

by Siddha Hover, posted in Pandora Report

Highlights include a new dengue serotype, bird flu in Australia, Peruvian bats and influenza A, mutating viruses, and HHS bolstering international pandemic preparedness. Happy Friday, and Happy Halloween!

First New Dengue Virus Type in 50 Years

For the first time in half a century, a new serotype of dengue has been discovered. The strain, found in Malaysia, is phylogenetically distinct from the existing four serotypes. The discovery will complicate existing vaccine efforts, which are already quite complex – prior to this discovery, dengue possessed four distinct serotypes. To date, this newest serotype has only been identified in one outbreak.

Science – “Scientists have discovered a new type of the virus that causes a centuries-old pestilence, dengue. The surprising find, announced at a major dengue conference here today, is bound to complicate efforts to develop a vaccine against a tropical disease that is becoming a more pervasive global menace. But it could shed light on where the pathogen came from and whether it is evolving into a greater threat. The finding “may change the way we think about dengue virus evolution and emergence,” says Duane Gubler, a dengue expert at the Duke-NUS Graduate Medical School in Singapore.”

Second bird flu outbreak in Australia

New South Wales has experienced its second outbreak of avian influenza. For some reason, none of the press is including the nueraminidase type, refering to the virus simply as “H7” or as HPAI (highly pathogenic avian influenza). This is misleading – the strain is actually H7N2, which has a low pathogenicity. While a serious threat to poultry farmers – 18,000 birds have died from the virus already and a further 400,000 have been culled – it isn’t a serious threat to humans at this point.

ABC Australia – “Initial testing at the Elizabeth Macarthur Agricultural Institute confirmed the virus earlier today and the infected property has been placed under strict quarantine. The department says tests are being carried out to try to confirm the origin of the latest incidence, but it’s the H7 strain, not the H5N1 strain that’s dangerous to humans. It says all eggs and poultry in NSW remain safe to eat. NSW DPI chief vet, Ian Roth, says he can’t yet confirm how the virus spread.”

New flu virus found in Peruvian bats

If there’s one thing we’ve learned here at the Pandora Report it’s never touch a bat. Just don’t do it. Halloween is great, bats can be cute, but as carriers of everything from rabies (scary) to Ebola (very scary), we’re keeping our distance.  In further confirmation of this truism, a new influenza virus has been discovered in Peruvian bats. The Influenza A virus, appropriately named A/bat/Peru/10, and contains hemagglutinin (H) and neuraminidase (N) surface proteins entirely distinct from any seen before, prompting researchers to classify them as novel – H18N11. While the virus is thought to be capable of infecting humans.  thus far researchers have been unable to culture it in human cells. Hopefully, it will stick to bats – H18N11 is just too hard to say.

LiveScience – “The researchers found the new virus after testing samples from 114 bats in Peru. One sample, from a flat-faced fruit bat known as Artibeus planirostris, was found to have H18N11. Blood testing of other bats suggested that they may have been infected with H18N11 in the past. The researchers still do not know how H18N11 attaches to cells to enter them…So far, flu viruses from bats are not known to infect people. But bats are known reservoirs for other types of pathogens that have found their way to humans, such as Severe Acute Respiratory Syndrome. Bats are also are suspected to be the original source of the virus causing the current outbreak of MERS.”

Single mutation gives virus new target

By changing a single amino acid in the BK polyomavirus, researchers were able to completely alter its preferential binding site. Understanding this mechanism is a small step towards understanding things like why a virus switches to infect different cells (potentially increasing pathogenicity) or, in the case of viruses like MERS and H7N9, different hosts. Understanding this mechanism can help us predict which viruses may switch hosts  to eventually infect us.

R&D Mag – “Different cells have different bindings targets on their surfaces. A change in a virus’s binding target preference can be a key step in changing how that virus would affect different cells in a victim—or move on to a different species…Brown postdoctoral researcher Stacy-ann Allen, one of two lead authors on the paper, said the team learned of the single amino acid difference by comparing high-resolution structural models of the two polyomaviruses bound to their favorite sugars. Collaborators, including co-lead author Ursula Neu and co-corresponding author Thilo Stehle at the Univ. of Tübingen in Germany, produced those models using nuclear magnetic resonance spectroscopy.”

HHS Boosts Global Ability to Respond to Pandemics

HHS through BARDA has awarded four interrelated grants, to the WHO, PATH, Utah and North Carolina States universities respectively to boost funding for pandemic preparedness in developing countries. The WHO is receiving approximately $10 million in grants to support H7N9 preparedness in developing countries, while the university grants are each supporting onsite training programs in the same countries. This makes a lot of sense – helping other states by providing them the tools to develop their own pandemic preparedness efforts makes us all  healthier.

PharmPro – “The program provides cost-sharing to build vaccine manufacturing facilities that can produce influenza and other vaccines in developing countries and trains personnel from developing countries at U.S.-based universities in advanced vaccine production. The program also supports technical assistance for foreign countries to operate and regulate their facilities and to conduct clinical trials with influenza vaccines produced in the facilities.”

And because everyone needs a little good news occasionally: Baby born with HIV is still showing no sign of the infection after treatment stopped 18 months ago
