title: Epidemiological study on foot-and-mouth disease in cattle: seroprevalence and risk factor assessment in South Omo zone, south-western Ethiopia.
abstract: A cross-sectional sero-epidemiological study was conducted in seven districts of the South Omo zone, south-western Ethiopia, between October 2008 and May 2009 with the objective of determining the seroprevalence of foot-and-mouth disease (FMD) in cattle and identifying the potential risk factors associated with the disease. In total, 770 cattle sera samples were collected and submitted to the National Veterinary Institute (NVI), Debre Zeit, Ethiopia, for screening using the 3ABC-ELISA. The overall seroprevalence of 8.18% (n=63) was recorded in the study. The highest district-level prevalence was observed in Bennatsemay district (30.2%), and the lowest prevalence was in Malle and Debub Aari districts, each with prevalence of 6.3%. The difference in seropositivity of FMD in the studied districts was found to be statistically significant. From the various risk factors analysed, age of animal, contact history with wild animals, distance of the herd from parks and wild animals' sanctuary and movement pattern of herds in search of pasture and water from area to area were found to be significantly associated (P<0.05) with the seroprevalence of FMD. The results of this study showed that FMD is an important cattle disease in the study areas. Thus, an appropriate control strategy has to be designed and applied, which could involve regulation of transboundary cattle movement, prevention of contact with wildlife and vaccination against the circulating virus strain.
