为探讨成人散发急性病毒性肝炎的病原学构成，对近年住院的散发性急性肝炎２７４例，用ＥＬＩＳＡ、斑点杂交及ＰＣＲ进行血清病原学分型并作初步统计分析。结果：甲、乙、丙、丁、戊型肝炎分别占５１．８２％，２５．９１％，８．３９％，０．３６％，２０．０７％，其中混合感染占１３．８９％。５型肝炎标志物均阴性，占１０．２０％，其中药物性肝炎，占２．９０％。认为本地区甲、乙、丙、丁、戊５型肝炎均有散发，可单一感染，可混合感染，可能存在新型病毒性肝炎。此外，药物性肝炎应引起重视。
In order to explore the etiological composition of acute viral hepatitis in adults, 274 cases of sporadic acute hepatitis were collected in recent years. Serum etiological typing was performed by ELISA, dot blot and PCR, and preliminary statistical analysis was made. Results: A, B, C, D and E accounted for 51.82%, 25.91%, 8.39%, 0.36% and 20.07% respectively, of which mixed infection accounted for 13.89%. Type 5 hepatitis markers were negative, accounting for 10.20%, of which drug-induced hepatitis, accounting for 2.90%. It is considered that hepatitis A, B, C, D and E have been distributed in this area, which can be single infection and mixed infection, and there may be new type of viral hepatitis. In addition, drug-induced hepatitis should attract attention.
