Resumo: The risk of human infection with sylvatic chikungunya (CHIKV) virus was assessed in a focus of sylvatic arbovirus circulation in Senegal by investigating distribution - abundance of anthropophilic Aedes mosquitoes, as well as the abundance - distribution of CHIKV in these mosquitoes. A 1650 km(2) area was classified into five l- cover classes: forest, barren, savanna, agriculture - village. A total of 39,799 mosquitoes was sampled from all classes using human l-ing collections between June 2009 - January 2010. Mosquito diversity was extremely high, - overall vector abundance peaked at the start of the rainy season. CHIKV was detected in 42 mosquito pools. Our data suggest that Aedes furcifer, which occurred abundantly in all l- cover classes - l-ed frequently on humans in villages outside of houses, is probably the major bridge vector responsible for the spillover of sylvatic CHIKV to humans.
