摘要:

目的 分析2024年我国内脏利什曼病的疫情特征,为制定防控措施和策略提供科学依据。方法 收集2024年中国疾病预防控制中心传染病报告信息管理系统中全国内脏利什曼病病例信息,剔除疑似病例、重复病例和皮肤利什曼病病例,采用Microsoft Excel 2016软件建立数据库,并对内脏利什曼病进行描述性流行病学分析。结果 2024年我国14个省(自治区、直辖市)的120个县共报告内脏利什曼病病例278例,较2023年的299例减少7.02%。其中77个流行县共报告本地感染病例232例,43个非流行县共报告输入性病例46例。犬源型(山丘型)内脏利什曼病病例225例(占80.93%),野生动物源型(荒漠型)内脏利什曼病病例5例,人源型内脏利什曼病病例2例。报告病例主要分布于山西(108例)、河南(53例)和陕西(32例)等3个省,合计占全国报告病例总数的69.42%(193/278)。77个流行县中,山西省阳泉市平定县(18例)和阳泉市郊区(11例)、河南省林州市(13例)和登封市(11例)、河北省井陉县(12例)为主要流行县,合计报告病例占全国总病例数的23.38%(65/278)。内脏利什曼病复燃流行县主要集中在山西省(榆次区、左权县、太谷区、泽州区、闻喜县、上党区)、河南省(陕州区、卢氏县、殷都区、宜阳县、汝州市)、河北省(元氏县、雄县、下花园区)、陕西省(澄城县、米脂县)和北京市(房山区),共报告本地感染病例26例。内脏利什曼病发病高峰为8月份,男性和女性报告病例数分别为191、87例。报告病例主要分布于45~74岁年龄组,农民占全部报告病例数的53.96%(150/278)。结论 我国内脏利什曼病呈低度流行态势,但犬源型内脏利什曼病流行区范围逐渐扩大,应加强犬源型内脏利什曼病流行区的监测和防控。

Abstract:

Objective To investigate the epidemiological characteristics of visceral leishmaniasis in China in 2024, so as to provide insights into formulation of visceral leishmaniasis control measures and strategies. Methods Epidemiological data of visceral leishmaniasis cases in China in 2024 were collected from National Notifiable Diseases Reporting Information System operated by Chinese Center for Disease Control and Prevention. After excluding suspected cases, duplicates and cutaneous leishmaniasis cases, all data were input into Microsoft Excel 2016, and the epidemiological characteristics of visceral leishmaniasis cases were analyzed using at descriptive epidemiological method. Results A total of 278 visceral leishmaniasis cases were reported in 120 counties across 14 provinces (autonomous regions and municipalities) in China in 2024, with a decrease of 7.02% in relative to in 2023 (299 cases), and including 232 local cases reported in 77 endemic counties, and 46 imported cases in non­endemic counties. There were 225 cases with anthropozoonotic (mountain-type zoonotic) visceral leishmaniasis (80.93%), 5 cases with euzoonotic (desert-type zoonotic) visceral leishmaniasis, and 2 cases with anthroponotic visceral leishmaniasis, and these reported cases were predominantly distributed in three provinces of Shanxi (108 cases), Henan (53 cases) and Shaanxi (32 cases), accounting for 69.42% (193/278) of total cases in China. In 77 endemic counties, Pingding County (18 cases), Suburb District (11 cases) of Yangquan City in Shanxi Province, Linzhou City (13 cases) and Dengfeng City (11 cases) of Henan Province and Jingxing County (12 cases) of Hebei Province had relatively high counts of incident cases, accounting for 23.38% (65/278) of total cases in China. The counties with recurrent visceral leishmaniasis were mainly concentrated in Shanxi Province (Yuci District, Zuoquan County, Taigu District, Zezhou District, Wenxi county and Shangdang District), Henan Province (Shaanzhou District, Lushi County, Yindu District, Yiyang County and Ruzhou City), Hebei Province (Yuanshi County, Xiongxian County and Xiahuayuan District), Shaanxi Province (Chengcheng County and Mizhi County) and Beijing City (Fangshan District), with a total of 26 local cases reported. The incidence of visceral leishmaniasis peeked in August, and there were 191 male cases and 87 femles cases, respectively. The reported visceral leishmaniasis cases were found at ages of 45 to 74 years, and farmers were the predominant occupation (53.96%, 150/278). Conclusion The prevalence of visceral leishmaniasis is low in China; however, the endemic areas of mountain-type zoonotic visceral leishmaniasis is gradually expanding. Intensified surveillance and management of mountain-type zoonotic visceral leishmaniasis is recommended.
