Het voorkomen van tekebeten en Erythema migrans in de huisartsenpraktijken in Nederland.

Lyme disease is a bacterial, infectious disease caused by the spirochete Borrelia burgdorferi. The aim of this study was to get information about the geographic distribution of the occurrence of tick bites and erythema migrans in the Netherlands and the association with possible risk factors. Information about the occurrence of tick bites and erythema migrans was obtained through approaching all general practitioners in the Netherlands with a questionnaire. The response rate was 80%. In 1994 general practitioners saw about 33.000 patients with tick bites and about 6500 patients with erythema migrans. Environmental risk factors included the proportion of land covered by wood, land consisting of sandy soil or dry natural area, intensity of tourism and the population density of sheep and cattle
