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. Did you know that your birth year can help predict how likely you are to get extremely sick from an outbreak of an animal-origin influenza virus?

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
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
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.
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.
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.

- 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.
