摘要: 目的 分析2021年全国内脏利什曼病的疫情状况,为制订防治策略提供科学依据。方法 收集2021年国家传染病报告信息管理系统报告的全国内脏利什曼病病例信息,剔除疑似病例、重复病例以及皮肤利什曼病病例,建立数据库。采用Microsoft Excel 2016软件对内脏利什曼病三间分布进行描述性流行病学分析。结果 2021年全国14个省(自治区、直辖市)的81个县共报告内脏利什曼病230例,其中犬源型流行区病例180例,野生动物源型流行区病例4例,人源型流行区病例1例,非流行区输入性病例45例。病例主要分布于山西(127例)、陕西(35例)和甘肃(20例)等3个省,报告病例数合计占全国报告病例总数的79.1%(182/230)。全国44个县属于流行区,共报告本地感染病例185例;其余37个县属于非流行区,共报告输入性病例45例。其中,山西省平定县(33例)、阳泉市郊区(29例)、阳泉市矿区(18例)、襄汾县(10例)和陕西省韩城市(11例)为主要流行县,报告病例数占全国总病例数的43.9%(101/230)。内脏利什曼病复燃流行县主要集中在甘肃省(秦州区、西和县)、山西省(尧都区、和顺县、陵川县、沁县、屯留区、昔阳县)和河南省(新安县、新密市),共报告本地感染病例10例。甘肃省玉门市为新发流行县,报告本地感染病例1例。内脏利什曼病发病高峰为4月份。男女病例比为1∶0.4。农民和婴幼儿报告病例数分别占总报告病例数的47.4%(109/230)和24.8%(57/230);≥ 15岁年龄组占73.5%(169/230)。 结论 我国内脏利什曼病呈低度流行态势,但流行区范围逐渐扩大,应加强监测和防控。

Abstract: Objective To analyze the epidemic situation of visceral leishmaniasis in China in 2021 and to provide the scientific basis for formulating the prevention and control strategies. Methods Data on visceral leishmaniasis in 2021 was collected from the web-based National Diseases Reporting Information System. After excluding suspected cases, duplicates and cutaneous leishmaniasis cases, a database was established, based on which the distribution of visceral leishmaniasis was analyzed using descriptive epidemiological method with Microsoft Excel version 2016. Results A total of 230 cases of visceral leishmaniasis were reported in 14 provinces (autonomous regions and municipalities) in 2021, among them 180 cases were reported from mountain-type zoonotic visceral leishmaniasis endemic areas, 4 cases from desert-type zoonotic visceral leishmaniasis endemic areas, 1 case from anthroponotic visceral leishmaniasis endemic areas, and 45 cases were imported from non-endemic areas. These cases were mainly distributed in Shanxi (127 cases), Shaanxi (35 cases) and Gansu (20 cases), the total reported accounting for 79.1%(182/230) of the overall total in China. A total of 185 local transmitted cases were reported from 44 endemic counties; other 37 counties were of non-endemic areas, reporting 45 imported cases. The Pingding County, outer suburbs of Yangquan City, mining district of Yangquan City, Hancheng City, and Xiangfen County were the major endemic counties, with 33, 29, 18, 11 and 10 cases reported, respectively, the total accounting for 43.9% (101/230) of the overall total cases in China. In 2021, recurrence endemic counties of visceral leishmaniasis were mainly concentrated in Gansu Province (Qinzhou District, Xihe County), Shanxi Province (Yaodu District, Heshun County, Lingchuan County, Qin County, Tunliu District, Xiyang County) and Henan Province (Xin’an County, Xinmi City), with a total of 10 local cases reported. Yumen City in Gansu Province was the newly emerging endemic county with 1 local case reported. The peak incidence occurred in April. The ratio of male to female cases was 1:0.4. The number of reported cases in peasants and infants accounted for 47.4% (109/230) and 24.8% (57/230) of the total cases, respectively. The reported cases at age of ≥ 15 accounted for 73.5% (169/230). Conclusion Visceral leishmaniasis presents a low prevalence in China, whereas, the range of endemic area is gradually expanding. Thus, surveillance and control activities should be strengthened.
