Which country do you think is the biggest consumer of antibiotics? You’ll be shocked to see the results in this infographic. The organization, No More Epidemics, has also created an infographic on pathogens and poverty, depicting the “general trajectory of infectious disease outbreaks from outbreak to epidemic, showing the potential power of interventions to interrupt the course of progression.” You may want to rethink baking this weekend as the CDC is currently working to control an E. coli outbreak related to General Mills flour. Before we start our adventure down the biodefense rabbit hole, check out this experiment showing just how far sneezes really spread (brace yourself for a “violent explosion of saliva and mucus”).
The Importance of a Resilient Health System
Sure, this may seem like a pretty obvious concept but it’s something we still struggle with. The 2014 Ebola outbreak proved it and Zika virus is just adding some salt with a side of lime juice to the wound. Between climate change, spillover, and antibiotic resistance, the need for a resilient and robust public health system has never been more dire. “The point is that resilience in the health sector is not static but rather an ongoing and evolving state of affairs. Well-performing health systems provide sustained, equitable access to essential services for all without financial hardship. They are better able to bounce back when adversity strikes; are prepared to detect and respond to emerging disease threats; are able to adapt to adverse conditions; address a wide range of health challenges; and offer innovative solutions by leveraging diverse skills and views.” USAID is working to help fix holes in the existing system through their initiatives like Fighting Ebola: A Grand Challenge for Development and the newer Combating Zika and Future Threats Grand Challenge. The world is moving at a rapid pace and with innovation and globalization, the potential for a pandemic is only a flight away. Now is the time to strengthen our public health system.
NSABB Select Agent & Gain of Function Progress
A few weeks back we discussed the National Science Advisory Board for Biosecurity’s (NSABB)’s meetings regarding Gain-of-Function (GoF) work and their risk assessment with subsequent recommendations for evaluation and oversight of proposed GoF research. Six meetings and two workshops later, NSABB approved the final proposal. The May 24th, 2016 version is similar to the earlier draft however, specific examples of “studies of concern” were provided. Seasonal flu GoF studies are not considered concerning and NSABB did modify its definition of GoF Research of Concern. “The report has new wording that is apparently aimed at critics who have argued that the HHS should not review studies it funds, because that would represent a conflict of interest. The report says the HHS review ‘should be structured to avoid real or apparent conflicts of interest,’ but doesn’t specify how that can be done.” While implementation will be challenging and require immediate initiation, it’s believed that agencies won’t have trouble adapting to the new policy. You can also check out Gryphon Scientific’s final analysis on the risks and benefits of GoF research.

Ancient Plague Epidemiology
Get your Indiana Jones hat ready, we’re going back in time to look at bioarcheology and the Eyam plague outbreak of 1665-1666. Researchers used a stochastic compartmental model and Bayesian analytical models to study this outbreak that started in September 1665 in the Derbyshire village of Eyam. Updated data from parish records allowed scientists to study this specific outbreak in a more in-depth manner, leading to the discovery that both rodent-to-human and human-to-human transmission played an important role in the spread of the disease. “We also found that the force of infection was stronger for infectious individuals living in the same household compared with the rest of the village. Poverty significantly increased the risk of disease, whereas adulthood decreased the risk. These results on the Eyam outbreak contribute to the current debate on the relative importance of plague transmission routes.”
Health on the G7 Summit Agenda
Last week, international officials met for the G7 Summit and during this gathering the topic of infectious diseases and control methods came to the table. “At the G7 Ise-Shima Summit, leaders will consider issues including strengthening the response to public health emergencies, by taking into account the lessons learned from previous outbreaks, such as Ebola. In addition, they will discuss ensuring the provision of lifelong healthcare services, from maternal, newborn and child health, through to non-communicable diseases and aging, in the pursuit of universal health coverage (UHC)”. Ebola, Zika virus, and Yellow Fever are all hot topics (see what I did there…) of concern. Improving investment in pandemic response was a vital part of the G7, as well as endorsement of the Global Health Security Agenda. Hopefully, with more international awareness and investment, the practice of putting out infectious disease fires will be a thing of the past.
Zika Weekly Roundup
The WHO has released their latest global response report on the Zika virus outbreak. The report gives an overview regarding the Strategic Response Framework and Joint Operations Plan as well as current funding gaps for “critical activities until the end of June 2016, as well as the approach to setting a new strategy from July 2016 onwards.” You can also find a scoping review of the Zika literature here. 233 studies were compiled with findings that “several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV.” A woman in New Jersey has given birth to a baby girl with microcephaly, making her the second Zika-related microcephaly case in the U.S. Entomologists and medical experts are participating in a Zika Symposium and you can check out some of the presentations here. President Obama commented on the need for Zika funding during his speech in Elkhart, IN, this week, noting that “we need more who are willing to work with us to lower health care costs, give us the funding we need to fight public health challenges like Zika and the opioid epidemic — Joe Donnelly is working on that diligently.” Researchers are looking at the risk factors for eye abnormalities in congenital Zika infections and scientists are now raising concern over transmission related to oral sex. Lastly, as of June 1st, 2016, the CDC has reported 618 travel-associated cases in the U.S.

- First Locally-Acquired Chikungunya Case in Texas– The Texas Department of State Health Services has confirmed the first case of local transmission. ” A Cameron County resident got sick with the illness in November 2015 and was diagnosed with a lab test in January 2016. The case, however, was not reported to the local health department until last month. The investigation performed by the Cameron County Department of Health and Human Services determined the patient had not traveled, and the case was confirmed last week by testing at the US Centers for Disease Control and Prevention.”
- Edge of the Antibiotic Abyss – There’s been a lot of talk about antibiotic resistance and the impending dangers if we don’t act soon. Here’s an overview of the concerns and recent case that is causing so much worry. While it may not get the media attention of Zika virus, this is a very real issue and recent estimates indicate that we’re teetering on the edge of the antibiotic abyss.
- India’s HIV Blood Transfusion Transmission Reality– The National AIDS Control Organization has released their report following a petition by activist Chetan Kothari, revealing that at least 2,234 Indians have contracted HIV while receiving blood transfusions. Scarier yet, these cases occurred in the past 17 months. Kothari has pushed for investigations, citing that while it is mandatory for hospitals to screen donors, the cost of the test and limited availability of testing facilities (Mumbai has only three private hospitals with HIV testing facilities) makes this a growing threat to anyone requiring blood transfusions. India currently has around 2.09 million people living with HIV/AIDS.
- The European Centre for Disease Prevention and Control – The ECDC has updated its rapid risk assessment for the current yellow fever outbreak that is impacting Angola, DRC, and Uganda. “In the EU/EEA, the risk of yellow fever virus being introduced is limited to unvaccinated viraemic travellers coming from areas with active local transmission.”
