Rift valley fever - disease monograph series – 05
2016
Outbreaks of rift valley fever (RVF) are associated with the simultaneous presence and circulation of the virus by mosquito vectors; mosquito pressure (number of breeding sites and hatching frequency) which is highly dependent on environmental conditions, particularly heavy rainfall events; and the distribution of domestic animal hosts, essentially ruminants vulnerable to the increased vector/host contacts at night. Control strategies that promote the establishment of herd immunity through yearly vaccination in endemic regions can reduce the devastating impact of severe outbreaks. This paper provides etiology, incidence, transmission and epidemiological details of the disease as well as vaccine development strategies.
