Abstract

Background: Rift Valley Fever (RVF) is a transboundary mosquito-borne disease affecting humans and animals in Sudan, causing public health issues, trade impacts, high young animal mortality with hemorrhage and liver damage, and flu-like symptoms in humans. This study addresses research gaps existing since the 2007 RVF epidemic. Purpose: To determine RVF seroprevalence in animals within the study area and assess risk factors associated with seropositivity. Method: Active surveillance and a cross-sectional study using ELISA were conducted. A total of 620 samples from sheep (n=304), goats (n=144), and cattle (n=172) were collected across three clusters selected via two-stage cluster sampling. Results: Overall RVF seroprevalence was 22.90%. Pearson‘s correlation between clinical signs and laboratory tests was positive (R=0.029). Sex, district, and society were significant predisposing factors (P<0.05; χ2=7.261, χ2=35.28, χ2=4.83). Univariate risk factors of species and mortality were not significant (P=0.461, P=0.465), and multivariate analysis showed no significant risk factors (P>0.05). Herd prevalence was 25% in sheep, 21.53% in goats, and 23.88% in cattle. Odds ratios were 0.81 for mortality, 1.6 for gender, and 0.74 for society. The test demonstrated 92.72% sensitivity and 86.46% specificity. Conclusion: Overall RVF seroprevalence was relatively high in 2007, potentially due to the epidemic peak. Further investigation is required to ascertain this fact, and more work is recommended.
