A study was made of 110 cases of viral hepatitis diagnosed by general practitioners between 31 May 1982 and 30 June 1984. Hepatitis A was diagnosed in 53 patients, hepatitis B in 18 patients, hepatitis of both types A and B in one patient, and--by exclusion--hepatitis non-A non-B in 38 patients. Hepatitis A appears to be generally acquired by contact with infected persons or by travelling in endemic regions. In more than 50% of the hepatitis B cases, a hospital stay and/or ambulatory treatment were mentioned. All patients with hepatitis A became negative for anti-HA/IgM within 9 months after the diagnosis. 30% of the patients with hepatitis B remained positive for HBs Ag 9 months after diagnosis.
对1982年5月31日至1984年6月30日期间由全科医生诊断的110例病毒性肝炎病例进行了研究。53例患者被诊断为甲型肝炎，18例为乙型肝炎，1例为甲型和乙型肝炎，其余38例经排除诊断为非甲非乙型肝炎。甲型肝炎似乎通常是通过与感染者接触或在流行地区旅行而感染的。在超过50%的乙型肝炎病例中，提到了住院和/或门诊治疗。所有甲型肝炎患者在诊断后9个月内抗-HA/IgM转为阴性。30%的乙型肝炎患者在诊断后9个月时HBs Ag仍为阳性。
