为了解泰安市麻疹流行病学特点和麻疹监测系统运转状况 ,对 1999～ 2 0 0 3年麻疹监测和预防接种数据进行分析、评价。结果显示 :1999～ 2 0 0 3年共报告麻疹疑似病例 4 6 2例 ,较法定传染病报告系统 (15 4例 )高出 2 0 0 % ,其中确诊麻疹 16 2例。目前麻疹发病仍有明显春末夏初季节高峰 ,且每年首例麻疹出现早晚与年内病例多少 (r =0 77)及其疫情停止早晚 (r=0 74 )相关。麻疹发病主要因素为麻疹疫苗 (MV)实际接种率较低和免疫失败。麻疹疑似病例的及时报告、及时调查、合格血清标本采集率分别为 10 0 0 0 %、10 0 0 0 %和 96 5 4 %。 1999～ 2 0 0 3年MV常规免疫接种 82 4 799人次 ,年报告接种率均 >90 % ;对重点人群开展了 3轮MV强化免疫 ,接种 18784 17人次。表明正确实施MV预防接种是控制麻疹的基础 ;加强麻疹监测 ,提高监测质量 ,是加速控制麻疹的关键。同时要注重流动人口中儿童的计划免疫规范化管理 In order to understand the epidemiological characteristics of measles and the operation status of measles monitoring system in Tai’an City, the surveillance and vaccination data of measles from 1999 to 2003 were analyzed and evaluated. The results showed that a total of 4662 cases of suspected measles cases were reported from 1999 to 2003, which was 200% higher than that of the statutory communicable disease reporting system (154 cases), of which 162 were confirmed measles cases. At present, the incidence of measles still shows a clear peak in early spring and early summer. The incidence of measles in the first year of each year is related to the number of cases (r = 0 77) and the early or late termination of the epidemic (r = 0 74). The main factors of measles incidence are the low actual immunization rate of measles vaccine (MV) and immune failure. Timely reports and timely investigation of suspected cases of measles, the sampling rate of qualified serum samples were 100%, 100% and 96 5% respectively. Between 1999 and 2003, 82 4 799 MV vaccinations were routinely vaccinated, and the annual report vaccination rates were> 90%. Three rounds of intensive immunization against key populations were vaccinated with 18,784 vaccinations. This indicates that the correct implementation of MV vaccination is the basis for measles control. Strengthening measles surveillance and monitoring quality are the keys to accelerating the control of measles. At the same time we must pay attention to the standardized immunization of children in the floating population
