[A case-control study on risk factors of cystic echinococcosis in humans in Tibetan areas].
摘要
OBJECTIVE: To understand the risk factors of cystic echinococcosis in Tibetan population, so as to provide the reference for development of prevention and control strategies. METHODS: Four cystic echinococcosis highly-prevalent townships were selected from Naqu County of Tibet and Shiqu County of Sichuan Province, which had similar environmental and altitude conditions, from August to September, 2017. Applying the 1∶1 case-control study, a household survey was conducted to investigate the risk factors of echinococcosis in humans. RESULTS: < 0.05) were the risk factors of echinococcosis. As a result of the multivariate logistic regression analysis, only three risk factors, feeding with raw viscera, there being stray dogs around, and drinking water resource, were included in the regression model. CONCLUSIONS: Feeding with raw viscera, there being stray dogs around, and drinking water resource are the risk factors of echinococcosis in humans.
