    INTRODUCTION AND OBJECTIVES: Leptospirosis is a zoonotic infection caused by spirochaetes of the genus Leptospira, with humans being affected as incidental hosts. Leptospirosis is endemic in Sri Lanka. There is paucity of prospective data on the clinico-epidemiological characteristics, treatment profiles and outcomes of patients with ieptospirosis in Sri Lanka. METHOD: This was a prospective cross sectional study of patients, over 12 years of age, with a diagnosis of ieptospirosis based on the WHO surveillance criteria with subsequent laboratory confirmation, presenting to three hospitals in the Western province of Sri Lanka. RESULTS: Of a total of 178 patients, males (84.3%) between the ages of 40-49 years were more likely to be affected. 51.7% were direct admissions and 47.8% were transfers. Exposure to water potentially contaminated with rat urine was seen in the majority (71.9%). A significant proportion of patients developed acute kidney injury (66.9%). Penicillin was the most commonly used antibiotic for treatment (47.2%), however more than one antibiotic was used in 43.3%. The use of chemoprophylaxis by the patients was low (1.1%). Hemodialysis was needed for 36.5%. Recovery was seen in 71.3%, 2.8% died, 10.1% were transferred out and 15.8% were lost to follow-up. On discharge, 70.6% had been treated for severe leptospirosis. Mean length of hospital stay was 7.5 days (±5.1). CONCLUSION: The incidence of severe leptospirosis with organ dysfunction is higher in patients presenting to hospitals in the .Western province. Males aged 40-49 are most commonly affected. More than two thirds of the patients developed acute kidney Injury. Chemoprophylaxis rates were low.
