Chikungunya Outbreak in Country with Multiple Vectorborne Diseases, Djibouti, 2019-2020

Emilie Javelle et al. Emerg Infect Dis. 2023 Apr.

Abstract

During 2019-2020, a chikungunya outbreak occurred in Djibouti City, Djibouti, while dengue virus and malaria parasites were cocirculating. We used blotting paper to detect arbovirus emergence and confirm that it is a robust method for detecting and monitoring arbovirus outbreaks remotely.

Keywords: Africa; Chikungunya virus; Djibouti; arboviruses; chikungunya; dengue fever; dengue virus; malaria; military personnel; outbreak; parasites; vector-borne infections; viruses.
