A cross-sectional survey to analyse the risk factors associated with human cystic echinococcosis in an endemic area of mid-Wales

In mid-Wales, the prevalence of cystic echinococcosis (hydatid disease) in humans and other animals has been well documented. A cross-sectional study was therefore undertaken to examine the associated demographic and environmental risk factors for the disease in humans, in Powys, mid-Wales. Overall, 223 fully completed questionnaires were returned from a postal survey. Eighteen of the respondents had been treated for cystic echinococcosis (CE). No significant association was found between many of the well-established risk factors, such as dog or farm ownership, and treatment for CE, although women were more likely to have been treated for the disease than men.
