title: Investigation of risk factors for development of human hydatidosis among households raising livestock in Tibetan areas of western Sichuan province.
abstract: OBJECTIVE
  To identify factors influencing the development of hydatidosis in Tibetan areas of western Sichuan.
  
  
  METHODS
  A questionnaire investigation was carried out to collect data on factors related to hydatidosis among households raising livestock.
  
  
  RESULTS
  Analyses of data revealed that dogs rather than foxes were the most important source of AE transmission. People below 19 years old tended to suffering from CE rather than AE and people 19-38 years old, especially the females, were under an increasing risk of suffering from AE (female vs. male, OR = 2.438, CI = 1.317-4.514, P < 0.05). Increased risks of both AE and CE prevalence associated with nomadic life, aging, playing with dogs, not protecting food from flies, and raising yaks or sheep.
  
  
  CONCLUSIONS
  In addition to age, sex, environmental conditions and hygienic behaviors, raising yaks or sheep and playing with dogs also increase the risk of suffering from hydatidosis as well in this area.
