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。
In order to evaluate the immunoprophylaxis effect of measles, the epidemic situation of measles in Beijing in 2000 was analyzed. The analysis results of routine infectious disease reporting system and annual incidence of measles in Beijing in 2000 show that the prevalence of measles in this Municipality in Beijing is 3 31/10 million in the suburbs, followed by urban areas (20 6/10 million) and outer suburbs (0 86/10 million). The peak incidence of measles in April, the peak incidence of adult adults in Beijing ≥ 2.5 years of age. The incidence of measles among migrant workers was significantly higher than that of Beijing, with the highest incidence in the outskirts (2 2 70/10 million), followed by the suburbs (13 79/10 million) and urban areas (11 4/10/10 million) ). Adult onset peak ≥ 20 years old. Population density and population susceptibility are the main influencing factors of measles. Vaccination against measles not only can prevent the disease but also improve the clinical symptoms to a certain extent. Adult incidence accounts for a considerable proportion, and there is a clear peak incidence, appropriate immunization interventions should be taken.
