作者于1987年2月16日～1988年2月15日在四川五个点211 639人群中监测急性病毒性肝炎。其发病率为167.74/10万,其中甲型肝炎占24.51％;乙型肝炎占38.31％;非甲非乙型肝炎占24.51％,EB病毒和巨细胞病毒所致肝炎各占3.38％;混合感染占5.92％。病毒性肝炎中有14.93％重叠感染。发病高峰在春季。发病率,男:女=1.75:1。甲型肝炎20岁以下年龄组、乙型肝炎20～39岁年龄组的发病率明显高于其他年龄组,非甲非乙型较分散,5～19岁相对多一些,其他型别年龄组间无明显差异。355例急性病毒性肝炎患者中43.9％有接触史,36.6％有注射史。
The authors monitored acute viral hepatitis in a population of 211 639 at a five-point scale in Sichuan from February 16, 1987 to February 15, 1988. The incidence rate was 167.74 / 100 000, among which, hepatitis A accounted for 24.51%, hepatitis B accounted for 38.31%, non-A non-B hepatitis accounted for 24.51%, EB and cytomegalovirus accounted for 3.38% respectively, and mixed infection Accounting for 5.92%. There were 14.93% overlapping infections in viral hepatitis. Peak incidence in the spring. Incidence, male: female = 1.75: 1. The incidence of hepatitis A under 20 years of age, hepatitis B 20 to 39 age group was significantly higher than other age groups, non-A non-B type more dispersed, 5 to 19 years old relatively more, other types of age groups No significant difference. Of the 355 patients with acute viral hepatitis, 43.9% had history of exposure and 36.6% had an injection history.
