Objectives: Determine the sero-prevalence of rift valley fever (RVF) among slaughterhouse personnel in Makkah during Hajj and define personal and work place correlates. Materials and methods: A sample of 294 participants were chosen randomly from slaughterhouse personnel in Makkah during Hajj 1419 (1999). Data were collected through personal interviews using a pre-designed questionnaire consisting of personal and work place variables, e.g. age, nationality, type and hours of work. A blood sample was collected from each participant and tested by enzyme immuno-assay for IgG antibody using killed antigen for rift valley virus. Results: Of the total sample, 17% was seropositive for RVF. The rate of infection varied with country of origin: Syria (10.6%), Egypt (21.2%), Bangladesh (22.6%), Mali (47.1%) and Niger (50%). The number of animals slaughtered per hour and daily hours of work were significantly associated with prevalence of RVF (p<0.05).Multivariate logistic regression analysis showed that nationality and daily hours of work predicted 84.1% of the occurrence of RVF. Recommendations: Sero-surveys should be done among slaughterhouse personnel in Saudi Arabia and other countries particularly in countries known to be free from RVF, e.g. Syria and Bangladesh to assess the situation of RVF. The importation of animals from endemic areas should be banned.
