Abstract

We diagnosed 400 possible IgM-positive cases of chikungunya virus in Bo, Sierra Leone, during July 2012-January 2013 by using lateral flow immunoassays. Cases detected likely represent only a small fraction of total cases. Further laboratory testing is required to confirm this outbreak and characterize the virus.

Keywords: Africa; CHIKV; Sierra Leone; chikungunya virus; reemerging infectious disease; viruses.
