目的分析陕西省商洛市2005-2014年流行性腮腺炎的流行特征,为下一步制定防控策略提供依据。方法运用描述流行病学方法分析流行性腮腺炎疫情监测资料,了解其流行特征和趋势,随机抽取健康人群采集静脉血检测腮腺炎Ig G抗体。结果商洛市2005-2014年共报告流行性腮腺炎6 176例,无死亡病例,年平均发病率24.75/10万,常年均有发病,呈现5-7月、12月至次年1月2个发病高峰;3~15岁组病例占发病总数的77.70%,学生居多;2011年共采集健康人群血样1 400份,腮腺炎抗体阳性率70.07%,抗体阳性率随年龄增长而增高,<1岁人群抗体阳性率最低(29.00%),不同年龄组、城镇与农村人群抗体阳性率均有统计学意义。结论商洛市流行性腮腺炎发病呈现下降趋势,人群接种率较低,抗体水平不高,3~15岁学生是防控重点人群。
Objective To analyze the epidemiological characteristics of mumps from 2005 to 2014 in Shangluo City, Shaanxi Province, and provide the basis for further development of prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze epidemiological data of mumps to find out the epidemiological characteristics and trends of the epidemic.

The incidence of perennial morbidity all occurred from May to July, from December to January of the following year The incidence of mumps was 70.07%. The positive rate of antibody increased with age, and was less than 1 year old <1 year old The positive rate of antibody in population was the lowest (29.00%). The positive rates of antibodies in different age groups, urban and rural areas were statistically significant. Conclusion The morbidity of mumps in Shangluo City shows a downward trend. The population vaccination rate is low and the antibody level is not high. The students aged 3-15 years are the key prevention and control groups.
