In 2021, 1 246 cases of leptospirosis were reported in the EU/EEA, of which 837 were confirmed cases.
• The notification rate of confirmed cases in the EU/EEA was 0.20 cases per 100 000 population.
• The highest number of confirmed cases (308) was reported in France (0.46 cases per 100 000 population).
• After a substantial decline in notification rates from 2019 to 2020, cases again increased in 2021. This may be associated with changes in population behaviours and surveillance activities during the COVID-19 pandemic.
• The highest rates of confirmed cases were detected in 45–64-year-old males and 15–24-year-old females (0.44 and 0.14 cases per 100 000 population, respectively).
