对１９９６年４月～１９９７年３月期间就诊于武汉市儿童医院的１６８３例门诊腹泻患儿粪便标本进行了轮状病毒ＲＮＡ的聚丙烯酰胺凝胶电泳分析。在５１５份标本中检出了轮状病毒ＲＮＡ，阳性率为３０．６０％。所检出的轮状病毒２个组中，以第二亚组多见，占９８．２５％，２个亚组又可进一步分为五种电泳型，即Ｓ、Ｌ１、Ｌ２、Ｌ３、Ｌ４型，５种电泳型中以Ｌ１型为主，占轮状病毒ＲＮＡ阳性病例的５６．１２％。对患儿临床表现、年龄与阳性率进行比较发现，呕吐、咳嗽、粪检时镜下脂肪球的发生均与轮状病毒感染密切相关（Ｐ＜０．００５），且发病以２岁内为易感年龄。
From April 1996 to March 1997 during the visit to Wuhan Children’s Hospital, 1683 cases of outpatient diarrhea stool samples of rotavirus RNA polyacrylamide gel electrophoresis analysis. Rotavirus RNA was detected in 515 samples, with a positive rate of 30.60%. The two rotavirus groups detected in the second sub-group more common, accounting for 98.25%, two subgroups can be further divided into five electrophoretic types, namely, S, L1, L2, L3, L4 Type, five types of electrophoresis to L1 type, accounting for 56.12% of rotavirus RNA positive cases. The clinical manifestations, age and positive rate of children were compared, vomiting, cough, fecal examination when the occurrence of fat globules were closely related to rotavirus infection (P <0.005), and the incidence of 2-year-old Susceptible age.
