江苏省 1999～ 2 0 0 1年共发生麻疹爆发 30起 6 13例 ,其中 2 8起经实验室确诊 ,爆发病例数占全省麻疹监测系统确诊病例数的 16 1%。麻疹爆发主要发生在经济欠发达、计划免疫工作基础较薄弱的Ⅱ类地区 ,高发季节为前一年的 11月至次年的 3～ 6月 ,爆发病例主要为学龄前儿童及小学生 ,并且未免疫者占 2 6 1%。免疫空白的存在、疫情报告迟缓、处理不当是导致爆发疫情蔓延的重要原因。
Thirty-six (613) cases of measles outbreaks were reported in Jiangsu Province from 1999 to 2001, of which 28 were laboratory-confirmed. The number of outbreaks accounted for 16.1% of the total number of cases confirmed by the province’s measles surveillance system. The outbreak of measles occurred mainly in area Ⅱ where the economy was underdeveloped and the basis for planned immunization work was weak. The high incidence season was from November of the previous year to March to June of the following year. The outbreaks were mainly preschool children and pupils, Immunization accounted for 2 6 1%. The existence of immune blanket, slow reporting of the epidemic, improper handling is an important reason leading to the outbreak of the epidemic.
