摘要
目的 分析全国不同年龄组人群内脏利什曼病流行特点,为内脏利什曼病的防治提供科学依据.方法 收集2005年至2012年中国疾病预防控制信息系统报告的全国内脏利什曼病病例,按人口学特征分为婴儿组（＜1岁）、幼儿组（≥1岁且＜4岁）、儿童组（≥4岁且＜15岁）、成年组（≥15岁且＜65岁）和老年组（≥65岁）,对其性别、发病时间、地区分布等流行特征进行分析.结果 2005年至2012年全国内脏利什曼病累计报告病例2 979例,婴儿组、幼儿组、儿童组、成年组和老年组发病分别占总数的24.9％、21.7％、20.0％、32.4％、1.0％.婴儿组发病高峰主要集中在4月份;幼儿组报告病例数从9月份开始持续上升,12月份达高峰;儿童组集中在10月份;成年组、老年组发病高峰均集中在3月份.我国内脏利什曼病报告病例主要集中在新疆、甘肃、四川,但各年龄组内脏利什曼病病例的地区分布不同,新疆发病人群以婴儿为主,甘肃以幼儿、儿童为主;四川以成年人为主.发病至诊断时间婴儿组最短（11 d）,成年组较长（15 d）.结论 不同年龄组内脏利什曼病发病高峰呈现的时间先后不一;地区分布不均匀,主要集中在新疆、甘肃、四川;新疆发病人群以婴儿为主,甘肃以幼儿、儿童为主,四川以成年人为主.
Objective To analyze the epidemiologic features of visceral leishmaniasis in different age groups in China from 2005 to 2012,and to provide a scientific basis for prevention and treatment of the disease.Methods The visceral leishmaniasis cases were obtained from China disease epidemic monitoring information system from 2005 to 2012.All the cases were divided into subgroups by demographic characteristics：infant （〈1 year old）,childcare （≥1 and 〈4 years old）,child （≥4 and 〈15 years old）,adult （≥15 and 〈65 years old） and senior adult （above 65 years old）.The epidemiologic features,such as gender,season of disease onset and area distribution of visceral leishmaniasis were analyzed.Results The total reported visceral leishmaniasis from 2005 to 2012 were 2 979,among which cases in infant,childcare,child,adult and senior adult were 24.9%,21.7%,20.0%,32.4% and 1.0%,respectively.Infant cases were most reported in April; childcare cases in December which began to increase since September; child cases in October and adult and senior adult in March.The reported cases were mainly from Xinjiang,Gansu and Sichuan areas.However,age characteristics differed among regions,which were mainly infants,both childcare and children,and adults,respectively in this three areas.The duration from onset to diagnosis was shortest in infant group （11 d） and longer in adult group （15 d）.Conclusions The number of visceral leishmaniasis cases in different age groups peaks in different months.Regional distribution is not even.Cases are most concentrated in Xinjiang,Gansu and Sichuan areas.Infants predominate in Xinjiang,childcare and children in Gansu and adults in Sichuan.
