Seroprevalence and associated risk factors of Peste des petits ruminants in selected districts of Awi zone, Northwest Ethiopia

Abstract

A cross-sectional study to estimate the antibody seroprevalence of the PPR virus and determine the associated risk factors was conducted from February 2021 to May 2022 in the Guangua and Jawi districts of the Awi zone. Of the total 380 sera samples tested using cELISA, 231 (60.8 %) were found positive for the PPRV antibody. A significantly higher prevalence of 76.2 % (OR = 4.5, P = 0.000) was observed in the Jawi district than in the Guangua district (45.5 %). Seroprevalence of 61.9 % (109/176) in sheep and 59.8 % (122/204) in goats was also detected in the present study (P > 0.05). Significantly higher prevalence was revealed in old (69.7 %, OR = 3.4) and adult (65.7 %, OR = 2.3) age groups compared to young (48.9 %) age groups. A prevalence of 63.4 % and 55.6 % were reported in female and male animals respectively (P > 0.05, χ2 = 1.85). As evidenced by the serological test result, PPR is highly circulated in the Guangua and Jawi districts of the Awi zone. The higher circulation of the PPR virus, the uncontrolled movement of animals, and the regular practice of communal grazing systems in the area indicate the chance of continued dissemination within and to other places. Hence, proper implementation of prevention and control measures and further study on sequencing and characterization of the circulating virus are advised.
