The EU/EEA notification rate of 0.9 per 100,000 population for 2020 represents a further increase compared to previous years.

94.7% of the confirmed cases were reported as not vaccinated against TBE. The report presents detailed data about the number of confirmed TBE cases and rates per 100,000 population by country and year and by month from 2016–2020 as well as by age and gender of the patients.
