摘要： 目的分析2020年山西省黑热病流行特征，为有效防控黑热病提供参考依据。方法收集整理国家传染病报告信息系统中2020年山西省黑热病报告病例信息，采用Excel 2010软件对数据整理和作图，SPSS 18.0软件对不同地区报告病例数的年龄组间差异进行单因素方差分析。结果 2020年山西省6市18个县（区）共报告黑热病87例，较2019年增加85.11%，年发病率为0.23/10万；病例主要分布在阳泉（68例）、长治（7例）和临汾（6例）3个市；年发病率>1/10万的有平定县、阳泉市郊区、阳泉市城区、阳泉市矿区、襄垣县和大宁县，6县（区）病例数占总报告病例数的80.46%。除12月外，其他月份均有病例报告，报告病例发病高峰分别为5和7月。报告病例中男性57例，女性30例；5岁以下年龄组发病数占报告总病例数的25.29%，≥60岁年龄组占32.18%，40～59岁发病人群占26.44%；农民为主要发病人群，占报告总病例数的43.68%，散居儿童占26.44%，家务及待业人员占12.64%。结论 2020年山西省黑热病流行强度增加，流行范围扩大，疫情形势严峻，社会各方需加强防控意识和防控力度。

Abstract: Objective To analyze the epidemiological characteristics of visceral leishmaniasis (VL) in Shanxi province, China in 2020, and to provide a reference for the effective prevention and control of VL. Methods The data of VL cases reported in Shanxi province in 2020 were collected from the National Disease Reporting Information System and were collated. Excel 2010 software was used to process and plot the data, and SPSS 18.0 software was used to perform one-way analysis of variance for comparison of the number of reported cases between different age groups in different regions. Results In 2020, a total of 87 VL cases were reported in 18 counties of 6 prefectures in Shanxi province, which increased by 85.11% compared with the year 2019, with an annual incidence rate of 0.23/100 000. The cases were mainly distributed in Yangquan (68 cases), Changzhi (7 cases), and Linfen (6 cases). The counties/districts with an annual incidence rate of >1/100 000 included Pingding county, suburban, urban, and mining districts of Yangquan, Xiangyuan county, and Daning county, and 80.46% of the total reported cases happened in these counties/districts. The peaks of reported cases were in May and July, respectively, and no cases were reported in December. Among the reported cases, 57 were males and 30 were females; 25.29% of them were aged <5 years, 32.18% aged 60 and older, and 26.44% aged 40-59; farmers (43.68%) were the main susceptible population, followed by scattered children (26.44%) and unemployed persons (12.64%). Conclusion In 2020, the prevalence of VL increased and the epidemic area became wider in Shanxi province. It is a serious situation and awareness, prevention, and control should be strengthened.
