Review on Ebola evolution in Nature

The 2013-2016 Ebola epidemic in West Africa was of unprecedented size and devastation, but also stands a landmark for infectious disease genomics. By sequencing virus genomes directly from patient samples, scientists are now able to investigate how viruses evolve, transmit between individuals, and spread across country borders during outbreaks, directly informing infection control.

Travel-related Zika cases in Florida

Figure 1. Coverage plots of the included samples. Data here. Protocol here. In a collaboration with Scott Michael and Sharon Isern from Florida Gulf Coast University and Florida Department of Health, we have recently received several travel-related cases detected across Florida. We have now managed to sequence Zika virus genomes from three of these case and the data and analyses can be accessed here. (more…)

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. These epidemics also exposed how unprepared we are to handle infectious disease emergencies. This is also true when we consider hypothesized new clinical features of infection, such as the associations between Zika virus infection and severe neurological disease,…

Zika virus pilot (update)

We have now received several hundred de-identified clinical samples from the Dominican Republic and Colombia. Unfortunately, they all have extremely low viral lows (Ct values > 38 in the few that are positive), so we’re continuing our technology development. We are following a couple of different strategies: (more…)

Roots, Not Parachutes

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.

Feature in Politiken

The leading Danish newspaper Politiken had a feature on our work in the September 20th 2015 Sunday section. The article discusses our past and ongoing work with Lassa and Ebola. The full feature describes how we have investigated both Lassa and Ebola virus evolution based on our most recent papers in Cell and Science. (more…)

Lassa paper on the front page of Cell

In a large multi-disciplinary collaboration between partners in Sierra Leone, Nigeria, USA, and Europe, we have published our first study on Lassa virus evolution. The paper - which appears on the front page of the August issue of Cell - is the result of seven years of work on Lassa fever across West Africa. (more…)
