对青岛市１８３ 名急性散发病毒性肝炎病例进行了血清学分 型研究， 其 中甲 型 ３１ 例（１６９４ ％ ） ， 乙型 １１０ 例（６０１１ ％ ） ，丙型５ 例（２７３ ％ ） ，戊型１６ 列（８７４ ％ ） ，２１ 例未能分型（１１４８ ％ ） 。甲型肝炎的平均发病年龄最低，为２５８１ 岁；戊型肝炎的平均发病年龄最高，为４３４２ 岁；乙型、丙型和未分型肝炎平均发病年龄分别为３００５ 、３０７５ 和３０１２ 岁。各型肝炎均为男性多于女性，尤以甲型和丙型更为明显。甲型肝炎多发生在冬春季节，乙型、丙型和戊型肝炎无明显季节性。甲型和戊型肝炎有肠道暴露史的比例较高，分别为９５６５ ％ 和９１６７ ％ ；乙型和丙型肝炎有注射、输血和手术史的比例分别为１２５ ％ 和６０ ％ 高于甲型和戊型肝炎；未分型肝炎有注射、输血和手术史的比例为１５３９ ％ 。 A total of 183 cases of acute viral hepatitis were collected from Qingdao, of which 31 cases were type A (1694%), 110 cases (6011%) were type B and 5 cases (273% ), E-type 16 (874%), 21 cases failed to type (1148%). The average age of onset of hepatitis A was the lowest, at 2581 years; the average age of onset of hepatitis E was the highest at 4342 years; the average age of onset of hepatitis B, C and non-type hepatitis was 3005, 30 75 and 30  12 years old. All types of hepatitis are more men than women, especially type A and type C is more obvious. Hepatitis A mostly occurs in winter and spring, and hepatitis B, C and E are not obviously seasonal. Hepatitis A and E had a higher proportion of intestinal exposure, accounting for 9565% and 9167%, respectively. The rates of injections, transfusions and surgical history of hepatitis B and C were 125% and 60% higher than those of hepatitis A and E; the percentage of cases of unseparated hepatitis with injection, blood transfusion and surgery was 1539%.
