2005-2010年湖北省病毒性肝炎发病变化分析

Trends in incidences of hepatitis virus infections in Hubei province 2005-2010

目的分析湖北省病毒性肝炎的发病现状,为制订肝炎防治策略提供科学依据。方法从中国疾病报告管理信息系统中搜集2005-2010年湖北省病毒性肝炎病例,结合同期人口学资料进行流行病学统计分析。结果湖北省病毒性肝炎2005-2010年的发病率从120.31/10万增加到145.71/10万,其中超过85%的肝炎病例是乙型肝炎;甲肝发病逐年减少,乙肝、丙肝和戊肝发病逐年增加,甲、乙、丙和戊肝发病率年平均变化百分率分别为-13.00%、4.23%、28.78%和11.28%;15岁以下人群乙肝发病的比例在2005-2010年间显著降低。结论预防乙肝是病毒性肝炎防治工作的重点;疫苗在病毒性肝炎的防治中起到重要作用;应密切关注甲肝的发病,同时高度重视丙肝和戊肝的预防。

Objective To characterize the epidemiological features of the viral hepatitis in Hubei and to provide scientific evidence for viral hepatitis control. Method Viral hepatitis infection cases between Jan. 2005 to Dec. 2010 from Center for Disease Control of Hubei Province were collected. Results The incidence rate of viral hepatitis was increased from 120.31/100 000 in 2005 to 145.71/100 000 in 2010,and more than 85% hepatitis cases were reported as hepatitis B. There was a decreasing tread in hepatitis A since 2005,while hepatitis B, hepatitis C and hepatitis E were all increased. The average annual change in incidence rate for hepatitis A,B,C and E was 13%,4.23%,28.78% and 11.28%, respectively. The percentage of patients under 15 years old was declined through these years. Conclusions Prevention of hepatitis B is the focus of the viral hepatitis prevention.Vaccination plays an important role in the control of viral hepatitis.A close watch on hepatitis A prevalence is still required.Hepatitis C and hepatitis E infection should be seriously taken into consideration.
