北京市1990～1997年肝炎分型及其流行状况的分析

Classification and Analysis of Prevalence on Hepatitis in Beijing 1990～1997

摘要: 本文对北京地区１９９０～１９９７年肝炎的发病率及其发病型别进行了比较分析，结果显示北京地区的肝炎发病率呈明显下降趋势，即由１９９０年的１０６．４４／１０万降至１９９７年的４６．４６／１０万，肝炎的流行型别亦发生了明显的变化，即甲型肝炎逐年下降，儿童中的乙型肝炎发病率减少，而非甲非乙型和未分型呈逐年上升趋势。此结果说明７年来北京地区的肝炎防治工作取得了较好的效果，同时也提示我们在今后的肝炎防治工作中应相应地改变工作重点，设法有效地控制甲肝和乙肝以外的其他型别肝炎的流行。

Abstract: The data showed that the incidence rate of hepatitis in Beijing was decreased sharply, from 106.44/10 6 in 1990 to 46.46/10 6 in 1997. The hepatitis type A and hepatitis type B in children was decreased year by year, but the hepatitis type nonA nonB and unspecified were increased year after year. This result showed that the control of hepatitis made a good effect in Beijing. The authors suggested that the focux of hepatitis control should be changed into the types other than type A and type B.
