RIVM Report 216852001
From January 1996 consultations of gastro-enteritis are being registered in sentinel practices in the Netherlands. In parallel, from May 1996, a case-control study is carried out among patients consulting a general practitioner with gastro-enteritis and age-matched controls consulting the same practitioner with other complaints. Patients and controls were asked to complete a questionnaire and to collect a stool sample. With a questionnaire information was obtained about age, gender, highest education, nationality, visits abroad, swimming, consumed foods, foodhandling, chronic gastro-intestinal complaints, pet ownership and others. Stool samples were examined for Campylobacter, Salmonella, Yersinia, Shigella, E.coli O157/VTEC, rotavirus, adenovirus, astrovirus, SRSV and all intestinal parasites. This report presents the study design and results until September 1996. The overall incidence of gastro-enteritis based on the sentinel registration from January until September 1996 was 0.8 per 100 person years. A questionnaire and stool sample were received of 64% of the registered patients. In 53% of patients and 53% of controls a pathogen was found. The registration and the case-control is being continued in 1997.
