Those antibiotic-resistant bugs just won’t quit – researchers in Florida found drug-resistant organisms in the water and sediment from a sewer-line spill in 2014. If you’ve got live poultry in your backyard, make sure to check out the advice from the CDC as there’s been a large outbreak associated with poultry. The recent Salmonella outbreak across 45 states has resulted in 611 cases, 138 hospitalizations, and 1 death. With the news of the first CRISPR human trials starting next month, many are wondering if the pro-CRISPR team has their heads in the sand regarding gene-editing safety.
The Soviet Biological Weapons Program in Today’s Russia
The Center for the Study of Weapons of Mass Destruction (CSWMD) at the National Defense University has published their first WMD case study, focussing on the driving factors for Russia’s offensive program following the termination of the U.S. program in 1969. Raymond Zilinskas discusses President Nixon’s decision to end the U.S. offensive biological weapons program and why the Soviet decision was in such a sharp contrast. Through a review of the generations of Soviet bioweapons programs, “the two authors of an extensive history of the Soviet BW program, one of whom is the author of this paper, were able to collect sufficient information from their interviews with Biopreparat employees, autobiographies written by weapons scientists, and articles written by investigative Russian reporters to describe and discuss important aspects of Soviet decisionmaking concerning BW.” In the second part of the paper, Zilinskas focuses on the driving force behind the massive Soviet push for an offensive program in the 1970s and Vladimir Putin’s historical comments on the development of “high technologies including genetics”. Zilinskas notes that given the secrecy, it’s possible that Putin may be instituting a third generation BW program.
The Rise of HIV Cases
HIV data over the past 10 years has revealed an increased rate of infection in 74 countries. While AIDS deaths have fallen, the rate of new infections is growing. Researchers reported countries like Egypt, Pakistan, Kenya, the Philippines, Cambodia, Mexico, and Russia, have all seen increased HIV infections since 2005. “The new research, released at the International AIDS Conference in Durban, South Africa, also found that while the global number of new cases continues to decline, the pace has greatly slowed. New infections of HIV fell by an average of only 0.7% per year between 2005 and 2015, compared to the 2.7% drop per year between 1997 and 2005.” The data raises concerns about meeting the UN’s Sustainable Development Goal to see the end of AIDS in less than 15 years, not to mention the startling reality that we’re still a ways off from ending the HIV/AIDS epidemic. The study also found that women tend to die at younger ages from HIV/AIDS, which matches the age-disparate relationships that are prevalent. A recent BBC article on cultural practices in Malawi may give some insight as to why younger women may be at risk for HIV infections and subsequent AIDS deaths.
2016 Presidential Candidates on Nuclear Weapons
You can’t get much more on the agenda than a norovirus among GOP convention staffers, so here’s hoping global health security will make it to the agenda in this year’s presidential election. GMU Biodefense MS student Greg Mercer provides us with a recap of where the candidates stand on nonproliferation. Following the GOP convention, it’ll be interesting to see how the Democratic convention addresses WMD’s. “Working off draft copies of the two parties’ respective platforms, here’s a look at what the two-party system has to say about non-proliferation for the next four years. These are dramatic, confrontational texts, each calling out the opposing party’s leadership and policies.”
Zika Virus Outbreak – Weekly Status Updates
A study published in Science addresses the need for new control strategies with the most recent outbreak. “The rise of Zika after its long persistence as a disease of apparently little importance highlights how little we truly understand about the global spread of mosquito-borne viruses and other lesser known diseases,” says Justin Lessler, an associate professor of epidemiology at the Bloomberg School who led the study along with Lelia Chaisson, a student in the department. “Over the past decades, dengue, chikungunya, West Nile virus and now Zika have emerged or re-emerged across the globe. Yet why these viruses have expanded their range and others have failed to invade areas potentially ripe for their spread remains a mystery.” Within the paper, researchers touch on the two main theories as to why Zika is currently causing so many problems- the virus has mutated and become more infectious or pathogenic, or previous outbreaks were in small populations and produced little understanding of health effects. Senior Fellows with Results for America, Michael Gerson and Raj Shah, are discussing what the U.S. needs to do to fight Zika. Aside from resources (financial and trained personnel), they’re pointing to the need for the U.S. to take on global leadership to help coordinate a strategy, especially in the wake of the post-Ebola reviews that have been released. Florida health officials are currently investigating two potential cases of local transmission. As of July 20, 2016, the CDC reported 1,404 cases of Zika virus in the U.S.
E. coli Outbreaks Galore
Summer is the time for picnics and, sadly, food-borne illness. Twenty people have been hospitalized in Chicago as a result of an E. coli outbreak traced to the Carbón Live Fire Mexican Grill. Two customers who became ill have filed civil lawsuits against the company for compensation. There have been a total of 65 sickened from this particular outbreak. England has reported 151 cases of E. coli o157, including the deaths of two people. “PHE (Public Health England) has been working to establish the cause of the outbreak and has identified that several of the affected individuals ate mixed salad leaves including rocket leaves prior to becoming unwell. Currently, the source of the outbreak is not confirmed and remains under investigation; we are not ruling out other food items as a potential source.” As you previously read, Salmonella has also been quite present this summer via the 45-state outbreak involving backyard poultry.
Walmart Chemical Weapon?
Video footage was recently released that shows a man, police say, who has been accused of building a chemical weapon inside an Oxnard Walmart. Reports are saying that following his research online, the suspect, Martin Reyes, went into the store and began assembling a weapon from ingredients on the shelves and an electronic appliance. He used a store socket to plug in the appliance, which was designed to set off the weapon. Following his arrest, Reyes admitted the entire thing and told police how he had been planning to build the device. As more information is released regarding the event, we’ll keep you posted.

- Agent X Concerns– Engineering of botulinum toxin during the height of bioweapon development was a major concern as the toxin is extremely lethal. Known as Agent X, researchers at the Defense Threat Reduction Agency’s Joint Science and Technology Office (JSTO) have been addressing the potential for weaponization. “Using tenants of Better Buying Power 3.0, a DoD initiative to achieve dominant capabilities through innovation, JSTO collaborated with the U.S. Army Medical Research Institute of Chemical Defense (USAMRICD), the Israel Institute for Biological Research (IIBR) and Hawaii Biotech, Inc., to tackle this complex issue. By pooling resources, JSTO incentivizes productivity in industry and government, while creating a consortium aimed to develop the first novel small organic molecules BoNT inhibitors (SMIs) as well as provide proof-of-concept for regenerative medicine using insulin-like growth factor 1 (IGF -1)”
- Yellow Fever Outbreak Situation Report: The WHO released their sit-rep on the yellow fever outbreak that started in Angola in December 2015. As of July 8th, there have been 3,625 cases in Angola and 1,798 cases in the DRC. Kenya and the People’s Republic of China have confirmed imported cases as a result of travel. There is currently a push for mass vaccination campaigns to help control the spread to the disease.
- Headway in Ebola Vaccine– Soligenix, Inc. announced their positive preliminary proof-of-concept results in efforts to produce a heat stable subunit Ebola vaccine. “These studies identified a formulation that maintained the physical state of the Ebola subunit protein despite incubation at 40 degrees Celsius (104 degrees Fahrenheit) for 12 weeks.”
- Silk Road Disease Transmission– Researchers found some of the first solid evidence of disease transmission along the Silk Road. Bamboo sticks used (by travelers) as “bottom wipers” from a 2,000-year-old Chinese latrine pit were analyzed. Fecal matter samples from these bottom wipers were positive for eggs from four species of parasites. The parasites, including the Chinese liver fluke, “needs marshy conditions to complete its life cycle, so could not have come from the desert area around the ancient Xuanquanzhi relay station.”
