Abstract Rift Valley fever (RVF) is an emerging zoonosis posing a public health threat to humans in Africa. During sporadic RVF outbreaks 2008–2009 and widespread epidemics 2010–2011, 302 laboratory-confirmed human infections, including 25 deaths (case-fatality rate, 8%) were identified. Incidence peaked late summer early autumn each year, which coincided with incidence rate patterns livestock. Most case-patients adults (median age 43 years), men (262; 87%), who worked farming, animal or...
