Spatial epidemiology of animal Rift Valley fever in Yemen, 2000-2001

Rift valley fever (RVF) is an arthropod borne disease produced by a Bunyavirus belonging to the genus Phlebovirus. Several species of Aedes and Culex are the vectors of this virus that affects sheep, goats, buffalos, cattle, camels and human beings. The human disease is well known, especially during periods of intense epizootic activity. The initial description of the disease dates back to 1930. Until 2000, this disease was only described in Africa, and then outbreaks were also declared in the Kingdom of Saudi Arabia (2000-2001 and 2004) and in Yemen (2000-2001). Animal and human cases were recorded. This work presents a retrospective summary of the data collected on animal RVF cases during this epidemic in Yemen. Results from several RVF surveys were gathered from the Yemeni vet services and FAO experts. Geographical data (topographic maps and data freely available on internet) were used for the location of outbreaks. After cleaning checking and standardisation of location names, all data were introduced into a GIS database. The spatial distribution of outbreaks was then studied at two scales: national level and local scale in the Wadi Mawr area (Tihama plain, Western coast of Yemen).
