Monitoring the global leprosy situation

Every year, WHO collates epidemiological data on leprosy from all its Member States and publishes a consolidated report in English and French in the Weekly Epidemiological Record, typically around the end of August/beginning of September, for data pertaining to the previous calendar year. These data are provided by countries.

The publications of the most recent years are the most complete in terms of Member States that submitted data; they capture > 99% of the global leprosy burden. The analysis includes informative tables with the latest figures by country on case detection (disaggregated by disease type, gender, age group, disability status and immigration status) and treatment outcomes, as well as trend analysis for selected indicators by WHO Region as well as for global priority countries over the past 10 years.
