Abstract: Objective To analyze the endemic situation of schistosomiasis in Hunan Province in 2019, so as to provide insights into the achievement of transmission interruption of schistosomiasis in the province in 2020. Methods The data pertaining to Schistosoma japonicum infections in humans and livestock and snail status were captured from Hunan Province in 2019 and analyzed. Results Schistosomiasis was endemic in 281 townships (towns) from 41 counties (districts) of 6 cities in Hunan Province by the end of 2019. A total of 991 900 persons received blood testing in Hunan Province in 2019, and 22 773 were positive for the blood testing, with sero?prevalence of 2.30%. All stool examinations were negative in 22 933 individuals detected. The high sero?prevalence was seen in Nanxian County, Anxiang County and Ziyang District. Currently, there were 5 034 cases with advanced schistosomiasis detected in Hunan Province, and they were predominantly identified in Yuanjiang City, Heshan District and Yueyang County. There were 44 963 bovines fenced in schistosomiasis?endemic villages in Hunan Province in 2019, which were predominantly distributed in Yuanjiang City, Hanshou County and Ziyang District, and no positives were detected in 1 996 bovines receiving blood testing or 20 684 bovines receiving stool examinations. In 2019, there were snail habitats of 1.73 billion m2 found in Hunan Province, which were mainly found in Yuanjiang City, Hanshou County and Yueyang County. Conclusion The endemic situation of schistosomiasis further decreases in Hunan Province in 2019; however, there is still a risk of schistosomiasis transmission in local areas of the province.

摘要: 目的 分析2019年湖南省血吸虫病疫情,为全省2020年实现血吸虫病传播阻断提供参考。方法 对2019年湖南省人群、家畜血吸虫病病情以及螺情进行分析。结果 截至2019年底,全省共有6个市、41个县(市、区)、281个乡(镇)流行血吸虫病。2019年全省血检 99.19万人·次,查出阳性22 773人·次,阳性率为2.30%;粪检22 933人,结果均为阴性。血检阳性率较高的地区是南县、安乡县、资阳区。全省尚存晚期血吸虫病病人5 034例,主要集中在沅江市、赫山区、岳阳县。2019年湖南省血吸虫病流行村共有存栏耕牛44 963头,其中血检1 996头,粪检20 684头,均未查出阳性,耕牛存栏主要集中在沅江市、汉寿县、资阳区。2019年湖南省实有钉螺面积17.3亿m2,主要集中在沅江市、汉寿县、岳阳县。结论 湖南省血吸虫病疫情进一步下降,局部地区仍然存在血吸虫病传播风险。
