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.
