目的了解西安市2005年麻疹发病情况,分析流行原因和探讨控制策略。方法对西安市2005年法定传染病报告系统和麻疹监测系统的麻疹发病资料,用SPSS 12.0进行描述流行病学分析。结果西安市2005年麻疹发病926例,发病率为12.56/10万;流动人口发病442例,占47.7%,发病率为42.21/10万;全年各月均有发病,3~4月发病584例,占全年病例数的63.1%;病例中<8月龄占11.0%,8月龄~14岁占63.8%,>14岁占25.2%;麻疹病例无麻疹疫苗(MV)免疫史者占37.7%,免疫1剂占19.9%,免疫≥2剂占4.2%,免疫史不详占38.2%;男女性别比为1.35∶1。结论西安市2005年麻疹发病率总体水平较高,流动人口较多的城区发病率更高,发病人群中MV接种率较低,应探索非免疫规划人群控制麻疹的策略,以降低麻疹的发病率。
Objective To understand the incidence of measles in Xi’an in 2005, analyze the epidemic reasons and explore control strategies. Methods The epidemiological analysis of measles in the report system of legal infectious diseases and measles monitoring system in Xi’an in 2005 was carried out with SPSS12.0. Results The incidence of measles in Xi’an in 2005 was 926, with an incidence rate of 12.56 / 100 000. The incidence of migratory population was 442 (47.7%), with an incidence rate of 42.21 / 100 000. The incidence of measles in the whole year and the incidence of 584 Cases, accounting for 63.1% of the total number of cases in the year; cases <8 months accounted for 11.0%, 8 months to 14 years old accounted for 63.8%,> 14 years old accounted for 25.2%; measles cases without measles vaccine (MV) 37.7%, 19.9% for immunization, 4.2% for immunosuppression, 38.2% for immunization history, and 1.35:1 for males and females. Conclusion The overall incidence of measles in Xi’an was high in 2005 with a higher morbidity rate in urban areas with more floating population and a lower MV vaccination rate in the affected population. The strategy of controlling measles in non-immunized population should be explored to reduce the incidence of measles .
