江苏省在 1999年分两类地区开展了麻疹监测 ,一类地区为经济较发达、计划免疫工作基础好、麻疹发病水平较低的苏州等 4个市 ;而以南京、徐州等 9个市为二类地区。全年麻疹监测系统报告疑似麻疹 938例 ,而法定传染病常规报告系统报告 846例 ,前者比后者多 92例。对两类地区麻疹发病特点的比较结果显示 :一类地区和南京市 ,麻疹病例≥ 15岁的占病例总数的 6 6 3% ;二类地区 (除外南京市 ) <15岁的病例占病例总数的 90 8% ,其中 <10岁的占 73 2 %。 1999年全省共发生 10起麻疹暴发 ,发病 2 18例 ,占全省监测系统确诊病例的 31 7%。 10起暴发 9起发生在二类地区 ,患者为学龄前儿童和小学生。这表明两类地区麻疹的流行病学特点有较大差别。
Jiangsu Province carried out measles surveillance in two types of areas in 1999: one is the four cities with relatively developed economy, well-planned immunization work and low incidence of measles; the other nine cities are Nanjing and Xuzhou Second-class area. The annual measles surveillance system reported 938 cases of suspected measles while the regular reporting system of notifiable infectious diseases reported 846 cases, the former 92 cases more than the latter. The comparison of the incidence of measles between the two regions showed that in one type of area and Nanjing, the number of measles cases ≥ 15 years old accounted for 63.3% of the total cases; in the second type (excluding Nanjing) cases <15 years old accounted for the total number of cases 90 8%, of which <10 years old accounted for 73 2%. In 1999, a total of 10 measles outbreaks occurred in the province with a total of 218 cases, accounting for 31.7% of the confirmed cases in the province’s surveillance system. Nine outbreaks occurred in 10 of the 10 categories, with pre-school children and pupils. This shows that the epidemiological characteristics of measles in both areas are quite different.
