Résumé : Objective(s) - Peste des petits ruminants (PPR) is a highly contagious disease with morbidity and mortality in small ruminants. Information about its epidemiological patterns is currently insufficient to develop appropriate control strategies in Plateau, Nigeria. This study aimed at identifying the distribution of the disease and the prevalence in sheep and goats, as well as at investigating the potential risk factors. Material and methods - A sample of 200 villages were investigated across the 17 Local government areas (LGA) of Plateau. In each village, serum samples were collected from 10 animals in two different herds. Presence of antibodies was evaluated using ELISA test. We considered a village positive if at least one animal was positive. We applied a mix model with nested random effects of LGA, villages and herds to account for the aggregation structure of the sampled animals. Results - In total, we sampled 2000 animals, 766 sheep and 1234 goats. The prevalence of positive villages was 84% with no significant difference across the LGA. Seroprevalence was higher in sheep (38.2%) than in goats (29.7%), and in adults (36.7%) than in young animals (29.3%). However, there is no significant difference between males and females. Lowest seropositivity level was observed in the local breed for goats and in Yankasa breed for sheep. Herds with a large size and made up exclusively of sheep were associated with higher seroreprevalence. Conclusion - The findings of this extensive seroprevalence survey imply that there is a widespread occurrence of PPR among small ruminants in Plateau. They also suggest that PPR is one of the major disease militating against sheep and goat production that call for effective control measures. Combined with other data generated by mobility, participatory epidemiological and socio-economics surveys, these results will support the development of effective preventive and control measures.
