INTRODUCTION: Leptospirosis, an emerging infectious disease, has a checkered history of outbreaks in Maharashtra. The last few years have seen a surge in number of cases in Mumbai. AIMS AND OBJECTIVES: The objective was to analyze the available disease surveillance data of leptospirosis in Mumbai for the years 2015 and 2016, highlighting the magnitude of the problem and assess disease surveillance data quality in terms of completeness, adequacy, and consistency, and identify gaps if any. MATERIALS AND METHODS: This is a record-based study. Daily line-listing and count data of leptospirosis in standard formats were scrutinized for analysis. RESULTS: There were 443 confirmed cases and 28 deaths from 2015 to 2016. The cases are present round the year, but the upsurge is observed during July to October. About 69% affected were males. Maximum affected age group is 26 to 40 years (31%). About 40% of the cases are reported within 24 to 48 hours of admission. The data are complete in all parameters in only 1.5% cases. Sociodemographic details are complete in 61% cases. Occupation was mentioned in only 21%. Reporting from private sector is neither adequate nor consistent. CONCLUSION: Gaps in the reporting are found in terms of completeness in both sociodemographic profile and clinicoepidemiological history. There were also issues in the adequacy and consistency of data. A strong and well-functioning disease surveillance system can gather enough evidence for planning prevention and control activities.
