Rapid assessment of coverage of doxycycline/azithromycin chemoprophylaxis against leptospirosis following floods, Kozhikode district, Kerala, 2018.

ABSTRACT

BACKGROUND: We estimated coverage of doxycycline chemoprophylaxis (200 mg once weekly) following floods in Kerala, India. METHODS: A cross-sectional survey was conducted to gather data on exposure to flood or stagnant water and receipt and consumption of chemoprophylaxis. RESULTS: Of 1573 individuals interviewed, 152 (10%) were exposed to flood water. Among these, 119 (78%) were eligible for chemoprophylaxis. Of those eligible, 58 (38.2% [95% confidence interval 30.8 to 46.1]) reported consuming the prescribed chemoprophylaxis. CONCLUSIONS: Despite the availability of chemoprophylaxis, consumption was less than ideal. We recommend targeted interventions to improve chemoprophylaxis coverage and public awareness campaigns to enhance its consumption among the affected population.
