title: [An epidemiologic survey on a type E hepatitis (HE) outbreak].
abstract: This article deals with a HE outbreak, which occurred in Sulagong Village, Pan-jin Township, Yining County, Xinjiang. There was a total of 214 patients involved in the village, with an attack rate of 6.15 percent. Among the patients young people formed the majority. The attack rate between 20 to 24 years of age reached 17.9 percent. Attack rate of pregnant women between 18 to 35 years of age was significantly higher than that of the non-pregnant ones. The condition in pregnant patients was rather severe. Their case fatality rate was 5.88 percent and abortion rate was 17.64 percent. By epidemiological investigation, it was shown that the chief contributing cause of the HE outbreak was probably contaminated drinking water, and direct or indirect contact with the patients in the infectious stage was also a risk factor.
