A total of 194 cases of acute viral hepatitis were notified between June and December 1976. Thirty-five (22.6%) out of 155 patients were positive for HBs Ag by counter-immuno-electrophoresis. The ethnic-specific morbidity rates per 100,000 were Chinese, 9.51; Malays, 3.20; Indians, 8.30 and others, 1.13; and the age specific attack rates were high in the 15 -- 24 and 25 -- 34 age groups, being 15.05 and 15.77 per 100,000 respectively. The male to female ratio was 3.04:1. Cases were not confined to areas with poor environmental sanitation. There were very few secondary cases. Unrecognized anicteric or subclinical cases probably play an important role in the transmission of viral hepatitis in the community. The possibility of transmission of hepatitis A by contaminated food was discussed.
1976年6月至12月期间，共报告了194例急性病毒性肝炎病例。155名患者中有35名（22.6%）通过对流免疫电泳检测乙肝表面抗原呈阳性。每10万人中按种族划分的发病率分别为：华人9.51；马来人3.20；印度人8.30；其他种族1.13；按年龄划分的发病率在15至24岁和25至34岁年龄组较高，分别为每10万人15.05和15.77。男女比例为3.04:1。病例并不局限于环境卫生差的地区。二代病例极少。未被识别的无黄疸型或亚临床病例可能在社区病毒性肝炎传播中起重要作用。文中讨论了受污染食物传播甲型肝炎的可能性。
