摘要
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 epidemiological features of vari-ous types of acute viral hepatitis in 5regions of Sichuan Province (211 639)population) form Feb.16,1987 to Feb.15,1988 were studied. One-year surveillancewas carried out and the results showed anincidence rate of 167.74 per 100 000 foracute viral hepatitis. The proportional dis-tribution of HA, HB, non-A,non--B Hepati-tis (HNANB),Hepatitis with EBV (HEB),Hepatitis with CMV (HCM) and Mixedinfection in all the patients being 24. 51％.38.31％, 24.51％, 3.38％, 3.38％ and 5.92％,respectively. There was a proportion of14.93％ for superinfection. The incidencedifferences in these regions ranged from110. 30 per 100 000 to 299. 95 per 100 000.Theincidence of hepatitis peaked in spring.and the sex ratio (male:female) for acuteviral hepatitis was 1.75: 1 (P<0.001).There was a peak of attack rate for HAin 0--19 age group. The incidence of HB in20-39 age group was obviously higher thanthat in other age groups .For HNANB, arelatively high attack rate was noticed in5--19 age group,but no significant age-dif-ferences were noted for HEB,HCM andMixed. of 355 patients with acute viralhepatitis, 43.94％ had a history of contact.and 36.62％ a history of injection.
