目的分析南安市急性乙肝监测项目,了解发病水平,为提高监测质量提供依据。方法用描述性流行病学分析急性乙肝监测项目实施前后乙肝报告数、病例急慢性分类和发病率等变化。结果 2011—2014年共报告乙肝8 496例,本地报告数占36.9%,外地占63.1%;2013年项目实施后报告总数较实施前上升12.4%,其中本地报告数上升4.5%,外地上升17.3%,本地报告病例上升速度有所放缓,报告病例有明确分类占98.1%,急性乙肝报告发病率从项目实施前的35.15/10万下降到实施后的11.09/10万,急性乙肝病例中位年龄提前2岁,职业信息更隐蔽。讨论南安市急性乙肝监测项目实施有效提高了乙肝病例急慢性分类的准确性,掌握了急性乙肝发病水平和特点,建议在乙肝疫情高发的地区推广实施急性乙肝监测项目。
Objective To analyze the acute hepatitis B monitoring project in Nanan City to understand the incidence level and provide the basis for improving the monitoring quality. Methods Descriptive epidemiological analysis of acute hepatitis B monitoring project before and after the implementation of hepatitis B reports, acute and chronic case classification and incidence rate changes. Results A total of 8 496 hepatitis B cases were reported in 2011-2014, with 36.9% of local reports and 63.1% of overseas reports. The total number of reports after the implementation of the project increased by 12.4% in 2013, of which the number of local reports increased by 4.5% and that in other places by 17.3% , The reported rate of local reporting slowed down, with a clear classification of reported cases accounting for 98.1%, the incidence of acute hepatitis B reporting decreased from 35.15 / 100000 before implementation to 11.09 / 100000 after implementation, the median age of acute hepatitis B 2 years in advance, career information more subtle. Discussion The implementation of the Acute Hepatitis B Monitoring Project in Nanan City effectively improved the accuracy of the acute and chronic classification of hepatitis B cases and mastered the level and characteristics of acute hepatitis B. It is suggested that the project of monitoring and monitoring acute hepatitis B should be popularized in areas with high incidence of hepatitis B.
