Ebola Outbreak Updates- From PHEIC Declaration to Vaccines
On Wednesday, the WHO declared the outbreak a PHEIC (Public Health Emergency of International Concern). “‘It is time for the world to take notice and redouble our efforts. We need to work together in solidarity with the DRC to end this outbreak and build a better health system,’ said Dr. Tedros. ‘Extraordinary work has been done for almost a year under the most difficult circumstances. We all owe it to these responders — coming from not just WHO but also government, partners and communities — to shoulder more of the burden.’ The declaration followed a meeting of the International Health Regulations Emergency Committee for EVD in the DRC. The Committee cited recent developments in the outbreak in making its recommendation, including the first confirmed case in Goma, a city of almost two million people on the border with Rwanda, and the gateway to the rest of DRC and the world.” A new case of Ebola has been identified in the city of Goma, which represents what the WHO is calling “a game-changer” since the city is a major transportation hub. On July 11th, it was announced that “the Democratic Republic of the Congo (DRC) ministry of health and government officials have agreed that Merck’s rVSV-ZEBOV is the only vaccine that will be used during the current, ever-growing Ebola outbreak in North Kivu and Ituri provinces. ‘Due to the lack of sufficient scientific evidence on the efficacy and safety of other vaccines as well as the risk of confusion among the population, it was decided that no clinical vaccine trials will be allowed throughout the country,’ the ministry said in its daily update yesterday. As of yesterday, a total of 158,830 people have been vaccinated with rVSV-ZEBOV, which clinical data suggest has as high as a 97.5% effectiveness rate against the virus.”
Trump Administration Gutting WMD Detection Programs
Despite 2017 pledges to secure, eliminate, and prevent the spread of WMD and related materials, a new investigation has found that such efforts through the Department of Homeland Security, have been drastically impacted. “Among the programs gutted since 2017, however, was an elite Homeland Security ‘red team,’ whose specialists conducted dozens of drills and assessments around the country each year to help federal, state and local officials detect such potential threats as an improvised nuclear device concealed in a suitcase, or a cargo ship carrying a radiation-spewing ‘dirty bomb.’ Another Homeland Security unit, the Operations Support Directorate, had helped lead up to 20 WMD-related training exercises each year with state and local authorities. The directorate participated in less than 10 such exercises last year and even fewer so far this year, according to internal Homeland Security documents.” The Homeland Security’s National Technical Nuclear Forensics Center has also seen a hit as their leadership is out and staffing has dropped from 14 to 3. “A separate Homeland Security component, the International Cooperation Division, which worked closely with foreign counterparts and the United Nations nuclear watchdog agency to track and stop the smuggling of dangerous nuclear materials overseas, has been disbanded.” “Homeland Security also has halted work to update a formal ‘strategic, integrated’ assessment of chemical, biological and nuclear-related risks.” The investigation also notes that more than 100 scientists and policy experts who specialize in radiological and nuclear threats, have either been reassigned or pushed into jobs that are wholly unrelated to their works. ‘The changes have undermined the U.S. government’s multi-agency commitment since 2006 to build and maintain a ‘global nuclear detection architecture,’ according to the present and former officials.”
Weaponized Ticks, Lyme Disease, and the Smith Amendment
Remember that time a conspiracy-theory book triggered an investigation into whether the DoD ever weaponized ticks? Well here we are…. Earlier this week the US House of Representatives voted on the Smith Amendment on Bioweaponization of Ticks – and it passed. A lot of this stems from stories of Plum Island and the whispers that Lyme disease actually originated from the testing site and ticks were either intentionally or accidentally released into the surrounding areas…triggering the disease a few decades ago. Since the release of a book on the “secret history of Lyme disease and biological weapons”, there’s been a renewed interest in the bedtime story of the disease’s sinister origin story. Unfortunately, the proposed investigation really doesn’t hit the nail on the head. For one, it’s been widely known for years that ticks, among other vectors, were a part of the bioweapons and biodefense research. Two, the “smoking gun” within the book that’s been used to reinvigorate interest, claims an interview with Dr. Willy Durgdorfer (the researcher who identified Lyme disease) gave confirmation of the true origin of the disease….alas, this was reported post-mortem, when he was not able to confirm or deny such statements. Third, Lyme disease actually has some pretty old origins. Last, but not least, this new amendment doesn’t even touch on Lyme disease…but rather focuses on if the DoD did experiments with insects and vectors as disease delivery systems…which we already know to be true. Ultimately, this does a disservice to not only the people with Lyme disease, but also encourages conspiracy theories.
Using “Outbreak Science” to Strengthen Usage of Models in Epidemics
If you’ve been on the frontlines of an outbreak, you’ve likely heard of disease modeling…but sometimes it can be hard to actually apply this technology to drive change. A new article has created “outbreak science” as an inter-disciplinary field to apply epidemic modeling in a way that can really help. “Nevertheless, the integration of those analyses into the decision-making cycle for the Ebola 2014–2016 epidemic was not seamless, a pattern repeated across many recent outbreaks, including Zika. Reasons for this vary. Modeling and outbreak data analysis efforts typically occur in silos with limited communication of methods and data between model developers and end users. Modeling “cross talk” across stakeholders within and between countries is also typically limited, often occurring within a landscape of legal and ethical uncertainty. Specifically, the ethics of performing research using surveillance and health data, limited knowledge of what types of questions models can help inform, data sharing restrictions, and the incentive in academia to quickly publish modeling results in peer-reviewed journals contribute to a complex collaborative environment with different and sometimes conflicting stakeholder goals and priorities. To remedy these challenges, we propose the establishment of ‘outbreak science’ as an inter-disciplinary field to improve the implementation of models and critical data analyses in epidemic response. This new track of outbreak science describes the functional use of models, clinical knowledge, laboratory results, data science, statistics, and other advanced analytical methods to specifically support public health decision making between and during outbreak threats. Outbreak scientists work with decision makers to turn outbreak data into actionable information for decisions about how to anticipate the course of an outbreak, allocate scarce resources, and prioritize and implement public health interventions. Here, we make three specific recommendations to get the most out of modeling efforts during outbreaks and epidemics.” From establishing functional model capacity and fostering relationships before things happen to investing in functional model capabilities, this guide could be a game-changer for outbreak response.
Building a Case of (non?)compliance Concern
Looking for a new book? Check out this review of Biosecurity in Putin’s Russia – “In the early 1990s, the world was rocked when defectors from the Soviet Union revealed the existence of a massive civilian and military biological-weapons program that had employed more than 65,000 people from 1928 to 1992, directly contravening the 1972 Biological and Toxin Weapons Convention (BWC). In 2012, Raymond Zilinskas, a leading biological- weapons expert, coauthored with Milton Leitenberg a comprehensive account of the program, The Soviet Biological Weapons Program: A History, a reference source so thorough that it ran to nearly a thousand pages. Last year, Zilinskas, in collaboration with Philippe Mauger, produced Biosecurity in Putin’s Russia, a sequel of sorts in which the cautionary note that Zilinskas and Leitenberg sounded earlier—that Russia’s relationship with biological weapons remained complicated, and that the current status of its old programs could not be verified—proved to have been foreshadowing.”
Modeling the Complexities of the Gut for Biodefense Application
“The Nutritional Immunology and Molecular Medicine Laboratory (NIMML), with research funding assistance from the Defense Threat Reduction Agency (DTRA), has developed a high-resolution model of the gut immune system to help solve emerging and re-emerging infectious diseases and biodefense challenges. The advanced model predicts new emerging behaviors and responses to biological threats. The gut ecosystem includes trillions of interactions between host epithelial and immune cells, molecules (cytokines, chemokines and metabolites) and microbes is a massively and dynamically interacting network, like a multidimensional jigsaw puzzle with pieces that are constantly changing shape. These interactions with cooperativity and feedback lead to nonlinear dynamics and unforeseen emergent behaviors across spatiotemporal scales. The NIMML agent-based modeling (ABM) of the gut uses an array of HPC-driven advanced computational technologies such as the ENteric Immunity SImulator (ENISI) – multiscale modeling (MSM). These models and tools simulate cell phenotype changes, signaling pathways, immune responses, lesion formation, cytokine, chemokine and metabolite diffusions, and cell movements at the gut mucosa.”

New WHO insight into 14 cases has identified 2 clusters that involved 4 of the infected people. “Of the 14 patients, 3 had been exposed to camels, a known risk factor for contracting the virus. Ten were men and four were women, and patient ages ranged from 22 to 80. Eleven had underlying health conditions, which is a risk factor for MERS. Ten were from Riyadh region, with other cases reported from Jeddah, Medina, Najran, and Al Qassim. One of the clusters involved two people living in the same household in Al Kharj in Riyadh region, a 22-year-old woman who had diabetes and epilepsy and a 44-year-old woman who had no underlying health conditions. The other cluster consisted of a 65-year-old male patient and a 23-year-old female healthcare worker in Riyadh. Five of the people died from their infections.”
CDC Announces E Coli Outbreak Linked to Ground Bison
Put down your bison burger and take a slow step back….”The US Centers for Disease Control and Prevention (CDC) and US Food and Drug Administration (FDA) have announced that they are collaborating with the Canadian Food Inspection Agency to investigate a multistate outbreak of E coli O103 and E coli O121 infections. Early epidemiologic and traceback information point to ground bison products as the likely source of the outbreak. As of July 12, 2019, there have been 21 individuals infected with E coli in this outbreak. In total, 6 individuals have been infected with the O103 strain, 13 cases of the O121 strain have been confirmed, and 2 individuals have been found to be infected with both strains.”
