Epidemiology of alveolar echinococcosis in southern Germany (Bavaria).
Alveolar echinococcosis is considered to be the most dangerous endemic parasitic disease for man in Central Europe. In Germany, unlike the neighbouring countries of Switzerland, Austria and France, only limited data on the prevalence and incidence of echinococcosis are available. Therefore, a retrospective cross-sectional study was conducted in order to investigate the epidemiology of echinococcosis in Bavaria, one of the two southern states of Germany. A standardised questionnaire was sent to all hospitals in Bavaria requesting information about patients seen from 1985 to 1989. In a second step a team of reviewers was sent to all relevant hospitals for active case finding in hospital statistics and medical records. A total of 216 patients with echinococcosis were detected of whom 58 had alveolar echinococcosis. According to these data, the prevalence in Bavaria was calculated to be 0.5 per 100,000 inhabitants with peak values in the counties of Swabia (2.4) and Upper Bavaria (0.6). The annual mean incidence of newly diagnosed cases amounted to 0.03 per 100,000. The distribution of prevalence in man was closely correlated to the infection rates in foxes throughout Bavaria (p < 0.05). Farmers are the occupational group with the highest risk to acquire echinococcosis with a prevalence/odds ratio of 14.6 for Swabia and 8.8 for Upper Bavaria, when compared to the general rural population.
