Arboviruses constitute an emerging public health threat, some of which are associated with human diseases ranging from mild febrile illness to encephalitis and even death. Surprisingly, most of these infections are poorly diagnosed in Africa, which obscures the assessment of their potential impact on public health or the burden of associated diseases. Building on findings of the discovery of the novel sandfly-borne phlebovirus in Kenya, the present study in collaboration with partners from Charite - Universitatsmedizin Berlin and the Univeristy of Bonn (Germany), seeks to monitor the spectrum of causative arboviruses, prevalence, and their social impact in Kenya.
