Résumé

Leptospirosis is an important re-emerging zoonosis of worldwide public health concern. Leptospirosis is caused by a bacteria of the genus Leptospira. There was an outbreak of leptospirosis in humans in Bungoma County in 2004 with severe consequences. Leptospirosis is enzootic in cattle in Bungoma County. This study was conducted to determine the risk factors for leptospirosis in humans in Bungoma County. The risk factors considered in this study were; rainfall patterns, livestock management practices (grazing and watering system), home slaughter of livestock, consumption of un-inspected meat, rodent infestation in homes, and frequency of contact of livestock keepers with veterinary extension staff. A cross-sectional survey was carried out in Kimilili and Mt Elgon sub-counties of Bungoma County, Kenya. The study was conducted between April and July of 2017. The locations were then sampled, and 400 households selected using a systematic random sampling technique. Questionnaires were administered to heads of the identified households. Descriptive statistics and the chi-square test were used to analyze the data. Secondary data from medical records in Kimilili and Webuye health facilities were taken to show the disease trends in the year 2004. The study reveals the risk factors for leptospirosis in Bungoma County which include the close association of the community and their livestock (87.9%, n=400), rodent infestation in homes (92.3%, n=400), slaughter of animals in non-designated areas (83.8%, n=400), consumption of un-inspected meat (83.0%, n=400) and low contact of the population with veterinary extension staff (63.7%, n=400). The risk factors under consideration in this study were observed in over 80% of the study population. The study recommends that knowledge of leptospirosis and its risk factors be enhanced for effective control and prevention program.
