Risk Factor Analysis for FMD seroprevalence
Study populations’ sex, age, herd size and district were considered as hypothesized risk factors for the occurrence of FMDV. Comparison of FMD seroprevalence between sex groups revealed a highest prevalence of 14.84% (57/384) in female cattle than male ones 3.90% (15/384) (Table 3). However, this seroprevalence variation was not statistically significant (P>0.05). Seroprevalence of antibodies against FMDV was compared between different age groups of the study populations. An increasing seroprevalence trend was observed with increasing age and the difference was statistically significant. FMD seroprevalence and herd size seems to have positive relationship in that an increasing seroprevalence of antibodies against FMDV was observed as herd size increases (Table 3) and this difference was statistically significant (P<0.05). Moreover, comparison of FMD seroprevalence between study districts revealed statistically significant variation.
