Resumo: Outbreaks of arthropod-borne viral infections occur periodically across Kenya. However, limited surveillance takes place during interepidemic periods. Using serum samples obtained from asymptomatic persons across Kenya in 2000-2004, we assessed (by indirect immunofluorescent assay) prevalence of IgG against yellow fever virus (YFV), West Nile virus (WNV), tick-borne encephalitis virus (TBEV), dengue virus serotypes 1-4 (DENV1-4), - chikungunya virus (CHIKV). Older persons on the Indian Ocean coast were more likely to be seropositive than children inl-: YFV = 42% versus 6%, WNV = 29% versus 6%, TBEV = 16% versus 6%, DENV-1 = 63% versus 9%, DENV-2 = 67% versus 7%, DENV-3 = 55% versus 6%, DENV-4 = 44% versus 8%, - CHIKV = 37% versus 20%. Among inl- samples, children in lowl-s were more likely to be seropositive for CHIKV (42% versus 0%) than children in highl-s. In Kenya, transmission of arboviral infection continues between known epidemics - remains common across the country.
