摘　　要：本文通报了2019年全国血吸虫病疫情,并对全国血吸虫病预防控制工作数据和455个国家血吸虫病监测点疫情监测数据进行了汇总和分析。截至2019年底,全国12个血吸虫病流行省(直辖市、自治区)中,上海、浙江、福建、广东、广西等5个省(直辖市、自治区)继续巩固血吸虫病消除成果,四川省维持传播阻断标准,江苏省新达到传播阻断标准,云南、湖北、安徽、江西、湖南等5个省维持传播控制标准。全国共有450个血吸虫病流行县(市、区),28500个流行村,流行村总人口7066.78万人。全国450个流行县(市、区)中,301个(66.89%)达到消除标准,128个(28.44%)达到传播阻断标准,21个(4.67%)达到传播控制标准。2019年全国尚存晚期血吸虫病患者30170例。2019年全国共开展询检查病12090712人,阳性1740764人;开展血检查病5158369人,阳性89753人;开展病原学检查327475人,阳性5人,其中急性血吸虫病病例1例。2019年全国共有19726个流行村开展了钉螺分布调查,7322个村查出钉螺,占调查总数的37.12%,新查出6个有螺村;共查螺585286.24 hm^2,查出有螺面积174270.42 hm2,其中新发现有螺面积64.20 hm^2,未发现感染性钉螺。2019年我国血吸虫病流行区现有存栏耕牛605965头,血检查病183313头,阳性1176头;开展粪检查病134978头,阳性7头。2019年全国共治疗血吸虫病患者28557例,扩大化疗1008083人·次;治疗病牛7头,扩大化疗耕牛296053头·次;开展药物灭螺总面积128754.26 hm^2,实际药物灭螺69605.55 hm^2,环境改造灭螺2847.00 hm^2。2019年全国455个国家血吸虫病监测点中,居民和耕牛平均血吸虫感染率均为0,未发现感染性钉螺。疫情数据分析显示,全国血吸虫病疫情总体保持低感染状态,但血吸虫病传播风险依然存在;为实现《“十三五”全国血吸虫病防治规划》目标、巩固血吸虫病防治成果,仍需加强血吸虫病精准防控。This report presented the endemic status of schistosomiasis in the People’s Republic of China at a national level in 2019,and analyzed the data collected from the national schistosomiasis prevention and control system and 455 national schistoso⁃miasis surveillance sites.Among the 12 provinces(municipality and autonomous region)endemic for schistosomiasis in China,Shanghai,Zhejiang,Fujian,Guangdong and Guangxi continued to consolidate the achievements of schistosomiasis elimination,Sichuan Province achieved transmission interruption,Jiangsu newly achieved the standard of transmission interruption and 5 provinces of Yunnan,Hubei,Anhui,Jiangxi and Hunan maintained transmission control by the end of 2019.There were 450 en⁃demic counties(cities,districts)endemic for schistosomiasis,including 28500 endemic villages covering 70667800 people at risk of infections.Among the 450 endemic counties(citis,districts),66.89%(301/450),28.44%(128/450)and 4.67%(21/450)kept the criteria of elimination,transmission interruption and transmission control of schistosomiasis,respectively.By the end of 2019,a total of 30170 advanced schistosomiasis cases were documented in China.In 2019,a total of 12090712 individuals re⁃ceived inquiry examinations and 1740764 were positive;5158369 individuals received serological tests and 89753 were sero⁃positive.A total of 327475 individuals received stool examinations and 5 were positive,including one case of acute schistosomia⁃sis.In 2019,snail survey was performed in 19726 endemic villages in China and Oncomelania snails were found in 7322 villag⁃es,accounting for 37.12%of all surveyed villages,with 6 villages with emerging snail habitats.Snail survey covered an area of 585286.24 hm2 and 174270.42 hm2 snail habitats were found,including emerging snail habitats of 64.20 hm2;however,no in⁃fected snails were identified.In 2019,a total of 605965 bovines were raised in the schistosomiasis endemic areas of China,and 183313 received serological examinations,with 1176 positives detected,whil
