Flawed Ebola study in Science

In a technical comment in Science, we show how a study published in 2015 by Hoenen, Feldmann, and others was based on faulty analyzes and a misunderstanding of the findings. The original article by the authors, as well as a later published erratum, failed to account for significant data analysis errors performed by Hoenen and colleagues.  (more…)

Navigating the Zika panic

The epidemics of Ebola virus in West Africa and Zika virus in America highlight how viruses can explosively emerge into new territories.

Infectious disease outbreaks continue to pose challenges to global health and security, prompting reactive countermeasures. Recently, severe outbreaks of Ebola and Zika virus were designated by the World Health Organization as “Public Health Emergencies of International Concern.” Other emerging viral pathogens have warranted similar attention, including virus outbreaks from Lassa, Chikungunya, avian influenza, Nipah, SARS, and MERS.

Rhabdo paper out in PNTD

Our new paper on the discovery of two novel rhabdoviruses in Nigeria is out in PLoS Neglected. In this study we used NextGeneration Illumina sequencing to look for viruses in the blood of sick and healthy individuals. Surprisingly, we discovered the presence of two completely rhabdoviruses in healthy individuals. (more…)
