Abstract

This study is an ecological study aimed to examine the ecological determinants influencing the occurrence of leptospirosis in Trang Province, Thailand. Secondary data on reported leptospirosis cases from 2017 to 2023 were obtained from disease surveillance reports of the Trang Provincial Public Health Office, 2017 to 2023. The ecological variables included average temperature, average rainfall, elevation, relative humidity, soil pH, and population density. The data were analyzed using binary logistic regression with the backward stepwise technique. The results showed that relative humidity (OR = 1.407, 95% CI: 1.135–1.744, p = 0.002) and average rainfall (OR = 1.029, 95% CI: 1.009–1.048, p = 0.003) were significantly associated with the occurrence of leptospirosis in Trang Province. In contrast, average temperature, elevation, soil pH, and population density were not significantly related to the occurrence of the disease. The findings indicate that certain ecological factors, particularly humidity and rainfall, play an important role in the distribution of leptospirosis in Trang Province. This information will be essential for supporting the planning of more effective disease surveillance, prevention, and control measures in the area.
