Community Behaviors That Affect the Incidence of Leptospirosis in West Jakarta, Indonesia

Leptospirosis is an infectious disease caused by a pathogenic Leptospira species transmitted directly or indirectly from animals to humans. It is endemic in Southeast Asia in several countries, including Indonesia and Thailand. Therefore, this study aimed to determine the effect of community behavior on the incidence of leptospirosis in West Jakarta in 2019. The study used a case-control design, and data were obtained from the West Jakarta Health Office. The sample included 140 respondents, consisting of 70 leptospirosis patients (cases) and 70 participants who did not suffer from the disease (controls) in a 1:1 ratio. In the bivariate analysis, there were significant effects on leptospirosis incidence from knowledge (odds ratio [OR] = 18.789), occupation (OR = 31.875), injury history (OR = 20.842), and recreation (OR = 0.294). Multivariate analysis showed significant effects based on occupation, present wounds, and recreation records. Occupation was a dominant factor in leptospirosis in West Jakarta (OR 54.116: 95% confidence interval: 4.435-660.372). The dominant factors for leptospirosis were risky occupations, followed by a history of injuries.
