Bovine leptospirosis is an emerging zoonotic disease that compromises farm economy. Keeping in view limited studies on bovine leptospirosis, this project was designed to estimate its sero-prevalence in flood-hit zone of Pakistan, along with its associated risk factors. A total of 385 serum samples were randomly collected from tehsils Rajanpur, Jampur and Rojhan of district Rajanpur with necessary information captured in data form for risk factors analysis. Chi-square test, univariable and multivariable logistic regression analyses were applied to check association of hypothesized risk factors with disease. The study showed 23.12% of the bovine samples positive for Leptospira antibodies with non-significant difference (P>0.05) between cattle (25.52%) and buffaloes (20.72%). The non-significant difference (P>0.05) of bovine leptospirosis among tehsils of study area presented 26.56, 21.88 and 20.93% in tehsils Jampur, Rajanpur and Rohan, respectively. Chi-square test analysis depicted body temperature and socio-economic status of worker positively associated (P<0.05) with the disease. The univariable analysis based on Mantel Haentzel test and Wald statistics found early age, confined system, fodder type, jaundice status, and socio-economic status of the animal’s owner as significant candidates (Odds ratio OR>1) while, multivariable logistic regression showed bovine specie, gender of animal, fodder type, jaundice status, and socio-economic status of the animal’s owner as key risk factors for leptospirosis dynamics (Odds Ratio>1). The study concluded that, the flood hit area is having considerable prevalence of bovine leptospirosis and is positively associated with presence or absence of certain animal, management and environmental factors.
