Prevalence and risk factors for echinococcal infection in a rural area of northern Chile: a household-based cross-sectional study.
Hydatidosis is a zoonotic disease of worldwide distribution caused by Echinococcus granulosus. Our study aimed to determine the prevalence of human and canine echinococcosis as well as the associated risk factors in a rural area of the Limarí province in northern Chile.A cross-sectional study was co...
