北京市2000年麻疹流行病学分析

Analysis of Epidemiology for Measles in Beijing,2000

为了评价麻疹的免疫预防效果 ,对北京市 2 0 0 0年的麻疹疫情进行了分析。北京市 2 0 0 0年常规传染病报告系统和年度麻疹发病统计表的分析结果表明 ,北京市本市人口麻疹发病率以近郊区为高 ,为 3 31/10万 ;其次是城区 (2 0 6 /10万 )和远郊区 (0 86 /10万 )。麻疹发病高峰在 4月 ,北京市成人发病高峰在≥ 2 5岁人群。而外来人员的麻疹发病率均显著高于北京市人口 ,也是近郊区发病率最高 (2 2 70 /10万 ) ,其次是远郊区 (13 79/10万 )和城区(11 4 0 /10万 )。成人发病高峰为≥ 2 0岁。人口密度、人群易感性是麻疹发病的主要影响因素 ,接种麻疹疫苗既能预防发病 ,也能在一定程度上改善临床症状。成人发病占相当比例 ,且有明显发病高峰 ,应采取适当免疫干预措施。

We analyzed the measles incidence in Beijing, in 2000 to evaluate the immune efficacy of measles vaccine. Based on statistical data of routine infectious disease reporting system and the annual measles incidence,it found that, in Beijing, the measles incidence was high in the suburbs(3.31/100,000), next was in city(2.06/100,000)and in outer suburbs(0.86/100,000).The disease peak of measles was in April. Population of≥25 years of age were largely involved,measles incidence in people who came from outside of Beijing were significantly higher than that of Beijing people,22.70/100,000 in the suburbs they lived,13.79/100,000 in outer suburbs and 11.40/100,000 in city,patients mostly occurred in adults of ≥20 years old. The chief factors in fluencing measles incidence were density and sensitivity of the population.Measles vaccination is not only a preventive measure but also in certain degree can improve the clinical symptoms. When quite number of adult measles patients were involved and an obvious measles disease peak appeared,the immunization measures should be taken to interrupt the disease epidemic.
