摘要
对广州、珠海和四会等地３７１例散发性急性病毒性肝炎进行血清学分型，结果甲型肝炎占２０．０％，乙型肝炎４４．７％，甲、乙型混合感染７．５％，丙型肝炎５．７％，丁型肝炎３．２％．经按年龄组进行分层分析，甲型肝炎２０岁以下年龄组，乙型肝炎２０～３９岁年龄组发病明显高于其他年龄组．甲型肝炎平均发病年龄２３岁，明显低于乙型、丙型和丁型肝炎（分别为３３岁、４７岁和４０岁）．各型肝炎的发病男性均多于女性．发病似无明显季节高峰．
A study was conducted to determine the serological type of acute sporadic viral hepatitis in Guangzhou,Zhuhai and Sihui.371 sera were tested for HBsAg Anti-HBcIgM by radioimmuno assay (RIA),and for anti HAVIgM,anti -HCV and HDAg by enzymelinked lmmunosorbent assay(ELISA).74 cases were diagnosed as acute hepatitis A (20.0%), 166 as acute Hepafifis B (44.7%), 28 as mixed infections with HAV and HBV (7.5%),21 as HCV infection(5.7%),12 as HDV infection(3.2%)and 70 cases indeterminate(18.9% ).Epidemiological analysis showed: the prevalence rate of hepatitis A in the group under 20 years old and that of hepatitis B in the group between 20～ 39 years old were obviously higher than that of the other age groups.The mean age of hepatitis A patients is 23 years old, 33 years old for hepatitis B, 47 for hepatitis C and40 for hepatitis D;the prevalence rate of male is higher than that of female in each type of hepatitis;seasonal change of prevalence rate is not signiticant.
