Seroepidemiological Investigation of Foot and Mouth Disease in Cattle Managed under Extensive Husbandry System in Tigray, Northern Ethiopia

3 Abstract: A cross-sectional multi-stage study was carried out to determine the seroprevalence of Foot and Mouth Disease (FMD) in cattle from October 2008 to June 2009 in selected zones of Tigray, northern Ethiopia. The overall seroprevalence of FMD in cattle was 15.4% (60/390) (95% Confidence interval (CI): 11.8 to 19). Among the assessed risk factors in this study, location (x = 10.9, P=0.012), age (x = 9.3, P = 0.009) and breed 22
