甘肃省2003年麻疹监测流行病学分析

目的了解甘肃省麻疹发病状况。方法对2003年麻疹监测数据进行了流行病学分析。结果2003年共报告麻疹疑似病例1631例,确诊1612例,发病率6·24/10万。麻疹发病呈散发和爆发并存的模式,爆发病例占总发病数的34·18%。麻疹发病以≤15岁儿童为主。在确诊病例中有麻疹疫苗(MV)免疫史者占55·09%,无免疫史者占10·85%,免疫史不详者占34·06%。发病主要原因是部分地区MV常规免疫未落实,爆发疫情不能及时报告、检测。结论应在加强MV初免和复种的同时,在重点地区适时开展强化免疫,同时提高接种质量,要加强基层疫情报告;建立麻疹实验室网络,提高麻疹IgM抗体检测率。

Analysis on the Epidemiology of Measles Surveillance in 2003 in Gansu Province

Objective To know the epidemiology of measles in Gansu. Method To analyze the epidemiology on the data of the measles surveillance in 2003. Results There were 1631 measles cases reported and the number of diagnosed cases was 1612 in 2003.The incidence rate of measles was 6.24 per 100 000. The cases included sporadic and outbreak cases and the proportion of outbreak cases was 34.18%.Less than 15 years old cases were higher than the other groups.Among all the diagnosed cases, the rate of immune cases occupied 55.09%, no immune cases were 10.86% and the immunity history not known cases amounted to 40.00%.The main reasons in measles incidence were that the normal immunity work of measles vaccine (MV) was not practical and the outbreak epidemic situation can not be reported and examined in time in some prefectures. Conclusion We should enhance the normal immunity of MV and in the same time we should carry out mass immunization in main prefectures properly.Basides,we should improve the quantities of MV immune and reinforce the reporting of the outbreak epidemic situation in grass roots,establish the measles laboratory network and enhance the examined rate of measles antibody (IgM).
