Notes from the Field: Rift Valley Fever Outbreak — ... - ISS-G20 Laboratorium Repository

Rift Valley fever (RVF) is a zoonotic mosquito-borne viral hemorrhagic fever (VHF) caused by Rift Valley fever virus (RVFV). RVF is endemic throughout most of Africa and the Arabian Peninsula and causes considerable morbidity and mortality among domestic livestock (1,2). Human infection occurs through contact with infected animals or their products or through bites from infected mosquitoes, mainly Aedes and Culex spp. (3). Human infections are typically asymptomatic or mild, usually manifesting as acute influenza-like illnesses (2). Severe disease, including hemorrhagic signs, occurs in approximately 10% of cases, nearly 10%–20% of which are fatal (2). Because of its socioeconomic impact and epidemic potential, RVF is a priority zoonotic disease in Uganda (4).
