湖南省2002～2006年麻疹发病年龄特征分析

ANALYSIS OF CHARACTERISTICS OF AGE DISTRIBUTION MEASLES IN HUNAN FROM 2002 TO 2006

[目的]解我省2002～2006年麻疹发病年龄特征,为制订消除麻疹策略提供依据。[方法]对麻疹病例年龄构成和年龄别发病率进行描述流行病学分析。[结果]全省2002～2006年麻疹主要发生在小年龄组儿童中,86.56%～89.44%的病例集中在﹤15岁儿童年龄组。2006年≤1岁儿童麻疹发病率大幅度上升,2006年≤1岁儿童发病率>300/10万,2006年≤1岁人群出现麻疹发病高峰。[结论]我省2005、2006年麻疹发病年龄特征发生较大变化,﹤1岁、1岁～、2岁～麻疹发病增多。应提高2剂次麻疹减毒活疫苗(MV)接种率和满8月龄婴儿MV及时接种率,做好2～7岁儿童第2剂次MV接种,建立和完善查验预防接种证制度,适时在重点地区和重点人群中开展MV强化免疫。

[Objective]To investigate the characteristics of age distribution measles in Hunan from 2002 to 2006,so as to provide basis for formulating strategy of eliminating measles.[Methods]Descriptive epidemiology were performed to analyze the agespecific attack rate and composition of age of patients with measles.[Results]Measles mainly occurred in low age hildren from 2002 to 2006,86.56% to 89.44% of patients with measles were mainly children below the age of 15 years. The incidence of measles among children below 1 years increased greatly in 2006,and the incidence among children above 1 years was above 300/104,children above 1 years reach the highest level in 2006.[Conclusion]The characteristics of age distribution measles had changed a lot in 2005 and 2006,and the incidence of measles increased among children below 1 years group,1 years to 2 years group,and 2 years to 3 years group. The inoculation rate of two times mevillin-L and promptly inoculation rate of infants at the age of 8 months should be improved,and efforts should be taken to strengthen the second inoculation of MV,and establish and complete the institution of checking the certifications of vaccination,reinforcement MV should be performed among high-risk population of high-risk areas at the right time.
