Each red dot on the above maps of Sweden represents a locality where one or more persons are presumed to have contracted TBE. The map to the left (a) shows the probable places of infection of all domestic human TBE cases with known place of infection (n = 308) recorded by the Swedish Institute for Communicable Disease Control (SMI) during the 6-year period 1987–1992. The map to the right (b) shows the corresponding data 20 years later, i.e. all domestically acquired human TBE cases with known place of infection (n = 1164) recorded during 2007–2012 (recorded by SMI and The Public Health Agency of Sweden). The light red areas on the maps represent the six counties that were analysed regarding wildlife abundance and TBE incidence. TBE data and wildlife hunting data from six counties (län) were analysed: Stockholms län (AB); Uppsala län (C); Södermanlands län (D); Östergötlands län (E); Västra Götalands län (O); and Skåne län (M). Each star denotes the location of a meteorological station that recorded data used in our analyses
