Sudan virus disease - A quick review

Abstract

The recent Sudan virus disease (SVD) outbreak in Uganda is a reminder of threat from Filovirus diseases. Unlike Ebola virus disease, no effective antiviral and vaccine is available for SVD. The outbreak was declared over after 115 days, with 142 confirmed cases and case fatality rate of 39%, before any dose of candidate vaccine could be used on contacts. We provide a quick review of up-to-date information on the Uganda outbreak, summary of previous outbreaks, and detail the existing SVD treatment and vaccine candidates. Evolution of disease attributes and the impact on public health were also discussed. For high consequence infectious disease like SVD, it takes international collaboration to be better prepared for the next outbreak.
