African horse sickness (AHS) virus causes severe epidemics when transmitted to horses by Culicoides vectors. A cross-sectional study was carried out in five areas of Burkina Faso to determine the seroprevalence of AHS virus in donkeys and to identify potential risk factors. A total of 460 sera were collected in 15 villages. A blocking enzyme-linked immunosorbent assay (ELISA) was carried out to detect AHS virus antibodies. The overall apparent seroprevalence was 72.6% indicating that the donkeys were infected with AHS virus. A multivariate logistic regression analysis was performed to determine the factors affecting the seroprevalence level. A significant effect between geographical areas was observed, confirming the role of the agroecological zone in the occurrence of AHS. Similarly, age and animal weight had significant effects on seroprevalence, whereas sex, coat color and herd size had not. This study highlighted the active circulation of AHS virus in donkeys in Burkina Faso.
