Happy Friday! We’re glad to start the weekend with a healthy dose of all things biodefense. Before we get too far down the nCoV-2019 rabbit hole…Senator Dianne Feinstein recently wrote a letter to DHHS regarding steps the department is taking to protect the U.S. against pandemics.
It’s almost that time of year and if you can’t make the January 28-30 ASM Biothreats conference, don’t worry – we’ll have great coverage. GMU Schar School Biodefense is sending graduate students to the conference to report out on these three days of all things biothreats. Check out previous years of our coverage here, where we provide detailed overviews of the talks and events. “ASM Biothreats is a one-of-a-kind meeting offering professionals in biodefense, biosecurity and biological threats the opportunity to exchange knowledge and ideas that will shape the future of this emerging field. ASM Biothreats offers a unique program that explores the latest developments and emerging technologies in the industry.”
The end of 2019 and the start of 2020 sees an uptick in discussion regarding artificial intelligence-driven weapons. Three of the world’s biggest plays – the United States, Russia, and China – are all strongly indicating that artificial intelligence (AI), considered a transformative technology, will be dominant in their respective national security strategies. Recent headlines on the topic include terms like “killer robots” and “Terminator-style war.” Indubitably, we are in an era of rapid and momentous technological advancement and discovery; however, the true application of these technologies is fairly narrow and now necessarily nefarious. Larry Lewis, a senior advisor for the State Department in the Obama administration and a member of the US delegation in the UN deliberations on lethal autonomous weapons systems, recently published an article in the Bulletin of the Atomic Scientists about the utility of AI in reducing the collateral damage of war. Lewis spent the last decade working to reduce the civilian casualties in war, and he found that such casualties were largely the result of inaccurate indicators regarding civilian presence or the misclassification of civilians as combatants. Though military applications of AI include autonomous weapons, this technology can also be employed to optimize automated processing to detection and as a decision aid to helping personnel interpret complex or vast sets of data. Though discussion tends toward the risks of AI technology, especially its military applications, Lewis endorses adding a new facet to the discussion that focuses on the benefits of AI technology in minimizing civilian casualties in warfare.
nCOV-2019 and the Wuhan Outbreak
The past few weeks have been busy with the news of this novel coronavirus cluster in Wuhan, China. Following the identification of it as a novel strain and the temporary name of nCoV-2019, public health authorities have been working to better understand the epidemiological aspects of the virus and how we can prevent further transmission. News of a case in Thailand, following travel to the affected region in China, quickly spread as it meant that cases were no longer contained in China. Interestingly, the Chinese woman whose infection was detected after her arrival in Thailand, had no exposure to the market that is considered to be the epicenter of the outbreak. “A new statement from the World Health Organization (WHO) today had several new details, including that the woman had not visited the Wuhan seafood market, which also sold live animals such as chickens, bats, and marmots, where most patients are thought to have been exposed. However, she reported regularly visiting a local fresh market before her symptoms began on Jan 5. That illness onset is later than that of the others infected in the outbreak, which ranged from Dec 8 to Jan 2, according to a Jan 12 update from the WHO. The incubation period for nCoV-2019 isn’t known, and authorities closed the seafood market on Jan 1.” 182 contacts are being monitored related to this case and eight febrile travelers at the Suvarnabhumi Airport have been isolated and tested (all were negative). Japan also confirmed their first case in a 30-year-old man who tested positive following a visit to Wuhan. On Thursday, officials released more information regarding a second family cluster in Wuhan (likely exposed via the same source), as well as findings from environmental testing at the market in Wuhan.
Antibiotic Tolerance Can Affect Combo Treatments, Study Finds
A team of scientists in Israel found evidence that antibiotic resistance in microbes may render combination therapies ineffective, a long-held fear that may now be reality. Combination drug therapy is a commonly used clinical method for treating infections caused by resistant microbes and to prevent the progression of resistance. This team monitored the evolution of Staphylococcus aureus strains in patients undergoing combination treatment and exposed the swift emergence of tolerance mutations trailed by the emergence of resistance. Tolerance mutation in antibiotics is a general term “used to describe the ability, whether inherited or not, of microorganisms to survive transient exposure to high concentrations of an antibiotic without a change in the MIC, which is often achieved by slowing down an essential bacterial process,” whereas antibiotic resistance is “the inherited ability of microorganisms to grow at high concentrations of an antibiotic, irrespective of the duration of treatment, and is quantified by the minimum inhibitory concentration (MIC).” After the discovery of tolerance to combination treatments in the S. aureus case, the scientists were able to expand the finding by measuring bacterial growth in Escherichia coli after drug combinations from four different antibiotic classes. Isolates with tolerance to norfloxacin and ampicillin promoted resistance in some of the combinations for treating E. coli. Therefore, the authors conclude that “rescue of resistance mutations by tolerance is a general phenomenon that may have crucial implications for the evolution of resistance in patients treated with combinations of antimicrobials.” A short article summarizing the study can be found here and the original publication can be found here.
WHO- Urgent Health Challenges for the Next Decade
The World Health Organization has released their list for the new decade – which was “developed with input from our experts around the world, reflects a deep concern that leaders are failing to invest enough resources in core health priorities and systems.” The list does not place challenges by priority, as they are all urgent and includes elevating health in the climate debate, delivering health in conflict and crisis, making healthcare fairer, expanding access to medicines, stopping infectious diseases, and more. Within each challenge, the WHO discusses what it is and what they are doing to help correct it.
While much attention has been to the novel coronavirus outbreak, more Ebola cases have been identified in the DRC. The latest situation report from The Who reports 8 new cases, including 3 in Beni.
