Abstract : The fifth and final year of research on the transmission ecology of tick-borne Crimean-Congo hemorrhagic fever (CCHF) virus in the West African savannah was devoted to integration and analysis of results, and continued surveillance at field sites. These observations of tick and virus activity in northern Senegal produced numerous new isolates of CCHF virus, principally from adult Hyalomma rufipes and H. truncatum; tick abundance at the prospective study sites remained low as in previous years. The results of our efforts during the five-year period are summarized for 23 studies grouped into 5 domains: (a) tick ecology and behavior, (b) experimental transmission studies, (c) vector competence and vectorial capacity, (d) epidemiology and epizootiology, and (e) studies of other associated arboviruses.
