急性病毒性肝炎患者年龄及病原学分析

Etiology and patient's age analysis of acute viral hepatitis

对２０５例急性病毒性肝炎的病原及年龄分布进行分析，结果显示：单一病毒感染，各年龄组均以ＨＡＶ、ＨＢＶ感染比例高；低年龄组以甲肝为主，随年龄增大，ＨＢＶ感染所占比例也增加，而４０岁以上戊肝感染比例增加；混合感染中，以ＨＡＶ与其他肝炎病毒共同感染为多见；未知病毒感染也占相当比例。此结果。

The pathogen and age distribution of 205 acute viral hepatitis patients was analysed.The results showed that propotion of HAV or HBV infection was high in each age group for single-viral infection patients.The HAV infection was dominated in low age groups.With the ageing of patients,the propotion of HBV increased.For the patients aged over 40 HEV increased.HAV patients complicated by other hepatitis were mainly seen in mixed infection patients.The propotion of unknown infection was considerable.Thus,the results provide a theoretic basis for the prevention and treatment of hepatitis.
