摘　　要：目的分析内蒙古2006—2010年甲乙类自然疫源及虫媒传染病的特点，掌握我区甲乙类自然疫源及虫媒传染病的流行特征，为有效控制提供依据。方法统计和分析2006—2010年中国疾病预防控制中心《中国疾病预防控制信息系纡窃中内蒙古地区甲乙类自然疫源及虫媒传染病数据。结果（1）2006—2010年，内蒙古甲乙类自然疫源和虫媒传染病发病60774例，死亡30例，总发病率为50．53／10万，年均发病率10．11／10万，无甲类发病，发病率呈现逐年升高趋势（P〈O．05）。发病前三位的病种分别是布病、出血热和炭疽。（2）地区分布：2006—2010年发病最高的地区前五位是锡林郭勒盟、乌兰察布市、呼伦贝尔市、兴安盟和赤峰市。（3）人群分布：高危职业主要是农民和牧民（P〈0．05），占5年发总病的87．37％；发病73．72％主要集中在25—55岁；男女性别比2．28：1。（4）时间分布：全年均可发病，发病高峰为3-6月份，约占发病总数的66．18％，5月份发病数最高、12月份最低（P〈O．05）。结论内蒙古甲乙类自然疫源和虫媒传染病发病呈现逐年增加趋势，有鲜明的地区聚集性、季节特点和人群特征，今后应该做好高发地区、高发人群和高发时间的预防控制工作。Objective The study analyzed and assessed the features and epidemiological characteristics of Class A and Class B nat- ural foci and insect-borne infections diseases in Inner Mongolia between 2006 and 2010, aiming to provide a reference for the ef- fective control of relevant diseases. Methods Data on Classes A and B natural foci and insect-borne infectious diseases in Inner Mongolia between 2006 and 2010 registered in the Disease Prevention and Control Information System of China of the Centers for Disease Control and Prevention of China were statistically analyzed. Results （1） Between 2006 and 2010, 60774 cases of Class A or Class B natural foci and insect-borne infectious diseases and 30 deaths were reported in Inner Mongolia, with an overall incidence of 50.53/100 000 and an average annual incidence of 10.11/100 000; the incidence was on the rise over the years （P〈0.05）, but no incidence of Class A diseases was reported. The three most prevalent diseases were brucellosis, hemorrhagic fever, and anthrax. （2） Geological distribution： the five regions with the highest incidence between 2006 and 2010 were Xilin Gol League, Ulanqab City, Hulunbeier City, Hinggan League, and Chifeng City. （3） Population distribution： farmers and herdsmen were among the most high-risk populations （P〈0.05）, accounting for 87.37% of the overall incidence within the 5 years. 73.72% of the incidence oc- curred between the ages of 25 and 55, and the ratio of incidence between male and female was 2.28：1. （4） Time distribution： the outbreaks occurred all year-round and peaked between March and June, accounting for 66.18% of the overall incidence. Most cases were reported in May and seldom occurred in December （P〈0.05）. Conclusion The incidence of Class A and Class B natural foci and insect-borne infectious diseases in Inner Mongolia is on the rise and exhibits strong regional, seasonal, and epidemiological patterns. Therefore, prevention and control of high-risk populations in highly prevalent area
