目的了解常德市2007-2009年麻疹、风疹血清学监测的状况和流行病学特点,为如期实现消除麻疹的目标,促进免疫规划工作发展提供科学依据。方法对常德市2007-2009年疑似麻疹病例的流行病学和实验室血清学检测结果进行分析。结果 2007-2009年共检测麻疹疑似病例标本1057份,其中麻疹IgM阳性360份,阳性率为34.1%。各区(县、市)均有疑似病例送检,发病高峰在每年的3-6月份。麻疹发病人群主要集中在1～5岁儿童。结论未免疫和不全程免疫是麻疹发病的主要原因,控制麻疹关键在于做好麻疹的免疫接种工作和加强疫情监测,提高实验室诊断率,及时控制麻疹局部暴发疫情。
Objective To understand the status and epidemiological characteristics of measles and rubella serological surveillance in Changde from 2007 to 2009, and to provide a scientific basis for achieving the goal of eliminating measles on schedule and promoting the development of immunization programs. Methods The epidemiological and laboratory serological test results of suspected measles cases in Changde City from 2007 to 2009 were analyzed. Results A total of 1057 suspected measles cases were detected in 2007-2009, of which 360 were positive for measles IgM, the positive rate was 34.1%. All districts (counties, cities) have suspected cases for submission, peak incidence in the annual 3-6 month. The incidence of measles is mainly concentrated in children aged 1 to 5 years. Conclusion The main reason for the non-immune and incomplete immunity is the incidence of measles. The key to controlling measles is to do a good job in measles immunization and to monitor the epidemic, to improve the diagnostic rate in the laboratory and to control the local outbreak of measles in time.
