| dc.description.abstract | Rift Valley fever (RVF) is a zoonotic, arthropod-borne viral disease important in domesticated ruminants. This disease is characterized by high mortality rates in young animals and abortions in pregnant ruminants. In Ethiopia, clinical RVF has never been detected and reported. However, it occurs almost in all neighboring country. Hence, this study was aimed for entomological surveillance of Rift valley fever virus mosquitoes vectors, assessment of community knowledge, attitude and perception toward the RVF and vector distribution model based risk mapping. A total of 200 mosquitoes were collected from the study areas of Borana Zone. Based on morphological identification, these mosquitoes were belonging to three genera; Culex (n = 48; 24%), Aedes (n = 147; 73.5%), and Anopheles (n = 5, 2.5%). A total of 244 participants were involved in the KAP assessment,among which majority of the participants 231 (94.67%) were replied that they had observed livestock diseases outbreak in their herds with different symptoms, 151(61.89%) responded that they had seen the sign of mass abortion in their herds, 130 (53.28%) replied that there was the history of heavy rainfall that precedes the event of mass abortion, and 168 (68.85%) mentioned that there had been mass young mortalities, and again 203 (83.20%) responded that they had seen huge mosquito population, 139 (56.97%) described that there are transboundary movements of animals. Ensemble model were developed using 11 explanatory variables. The variables contribute different amount where water Vapor pressure (54.4%) and soil type (29.9%) contribute the most while global land coverage and elevation were contributed the least which is about 1%. The model showed border regions of Ethiopia from southeastern to northwestern of the country were suitable for distribution of RVFV vector mosquitoes where Somali region has wide while Afar region has few patchy suitable areas.many parts of central and Northern Ethiopia is not suitable for RVFV vector mosquitoes. The questionary survey results suggest that the disease might once have occurred in the area during the historical enzootic periods while occurrence of potential mosquito vectors and model capture of broad risky areas particularly along the borde shared with endemic countries necessitates further studies of the diseases. | en_US |
