摘　　要：作者(1990.5—1992.4)采用PAGE和电镜技术,查获得149例腹泻病毒混合感染病例,进行了流行病学分析。共检出病毒5种13组,病毒混合感染率9.57％(149/1557)。其中多重感染为11.6％;双重感染为4.96％;重叠感染为3.73％。<20岁组为6.49％;>21岁组为3.08％;流行季节前期居多,散发流行在人口密集的拉萨、林芝和昌都地区。呕吐、发热、脱水和腹泻加重为主要临床特征。此外,文中对发现的冠状病毒从形态和分子结构上作了描述和流行病学分析,除证实在当地感染(3.73％)的存在外,讨论了HECV与人类腹泻的密切病因关系。From May, 1990 to April, 1992, 1557 feces samples were collected and examined with SDS - PAGE and EM, and the molecular epidemiological characteristics of mixed infections caused by multiple diarrhea viruses were studied. The total positive rate was 9. 57%, of which multiple infection rate was 1. 16% , double infection rate was 4. 69% , re-infection rate by both long type HRV and short type HRV was 3. 73%. The infection rate in the 5 -year old group was 2. 44%. The mixed infection rate was higher in the 20-year old group (3. 21%) than in other groups. Thte peak season of HRV infection (3. 28%) was early winter and spring. HECV diarrhea (with a positive rate of 3. 73%) was also discussed.
