Leptospirosis in the Delta Region of Tamil Nadu: A Retrospective Analysis in South India

Leptospirosis is a bacterial infection that targets multiple systems in our human body, and we are witnessing this in our routine clinical practice and ward rounds. In Thanjavur, which is commonly referred to as the Delta region of Tamil Nadu, agricultural workers, sewage workers, and all those individuals who are liable to work in rodent-infected environments are at increased risk. We found the prevalence of leptospirosis to be 17% (n = 85) during our study period from March 2024 to December 2024. Even though the prevalence was found to be considerably low, preventive measures like proper waste disposal, rodent control, and health education should be regularly taken at all levels.
