Abstract

Introduction: Peste des petits ruminants is a transboundary disease of major economic importance and imposes significant constraints on small ruminant production.

Methods: A cross-sectional study was employed in Dera and Gerar Jarso districts of the North Shewa zone, Oromia Region from February 2021 to March 2022, to estimate the antibody of PPRV and assess the associated risk factors. Blood samples (n = 662) were collected from sheep and goats. Cluster sampling strategy was employed to collect the data. Villages/Kebeles and individual small ruminants were randomly selected, while households were designated using a systematic random sampling method.

Results: An overall individual animal and flock level sero-prevalence was 10.3% (95% CI = 8.2-12.8) and 100% (95% CI = 96.3-100), respectively, from the c-ELISA test result. A sero-prevalence of 11.2% (95% CI = 8.7-14.4) in Dera and 8% (95% CI = 5-12.7) in Gerar Jarso districts was recorded.

Discussion: Flock size, age, sex, communal grazing, and watering system, new small ruminant introduction into a flock, and mixed rearing were significantly associated with PPR sero-positivity in sheep and goats. The chance of PPR occurrence in goats was 4 times (OR = 4; P = 0.000) more than sheep. Female sheep and goats were more likely to be sero-positive to PPR by 3 times (OR = 3.2; P = 0.003) than males. The newly introduced small ruminants had 4 times more odds (OR = 4.4; P = 0.000) of sero-positivity than animals being born at home. Small ruminants kept under communal grazing and watering system were nearly 12 times (OR = 11.5; P = 0.024) more likely sero-positive than privately managed small ruminants. Likewise, sheep and goats reared together were almost 9 times (OR = 9.4; P = 0.000) a higher chance of being sero-positive compared with separately reared small ruminants.

Conclusion: The finding of PPR virus antibodies in small ruminants from all study areas indicates endemic circulation of the virus. The implementation of regular vaccination could minimize the occurrence of PPR.
