摘　　要：目的分析2015—2019年贵池区国家血吸虫病监测点疫情,为制定血吸虫病预防控制措施提供依据。方法按照《全国血吸虫病监测方案(2014年版)》要求,对贵池区国家级监测点2015—2019年人畜病情、螺情和野粪感染情况进行分析。结果 2015—2019年,贵池区国家血吸虫病监测点累计开展本地人群血清学查病4 297人·次,血检阳性率从2015年的7.22%下降至2019年的2.48%;流动人口累计血清学查病1 274人·次,血检阳性率分别为8.00%、11.50%、7.58%、4.42%和7.91%。本地和流动人群均未查到粪检阳性者。五年间未发生本地感染急性血吸虫病病例,无新(复)发晚期血吸虫病病例。筛查猪92头,犬108条,均未发现粪检阳性家畜。累计调查钉螺面积219.49 hm^(2),共捕获活螺6 216只,活螺密度分别为2.84、1.08、2.91、2.14和0.88只/0.1 m^(2),未发现感染性钉螺。结论贵池区血吸虫病疫情总体呈下降趋势,但传播风险依然存在。需进一步完善血吸虫病监测体系,提高监测敏感性和水平,防止疫情反弹。Objective To analyze the surveillance results of schistosomiasis prevalence in a national surveillance site in Guichi District from 2015 to 2019 for evidence to develop strategies for prevention and control of schistosomiasis. Methods According to the requirements specified in National Schistosomiasis Surveillance Scheme(2014 version), we conducted surveillance over Schistosoma japonicum infections in population and livestock, snails and wild feces in Guichi District from 2015 to 2019, and analyzed the surveillance results of schistosomiasis prevalence. Results Totally, 4 297 local residents/times in the national schistosomiasis surveillance sites in Guichi District underwent serological examinations. Positive rate of blood test was decreased to 2.48% in 2019 from 7.22% in 2015. Serological studies performed in the floating population(a total of 1 274 individuals/times) showed that the positive rate was 8.00%, 11.5%, 7.58%, 4.42%and 7.91%, respectively from 2015 to 2019. No positive stool was found in the local and floating population. There were no local acute schistosomiasis infections, and no newly or reemerged cases of advanced schistosomiasis in the five years.Screening test was conducted in the feces from 92 pigs and 108 dogs, which showed no positive findings. A total area of 219.49 hm;was investigated for the snail infection, and 6 216 live snails were captured. The results showed that the density of live snails was 2.84, 1.08, 2.91, 2.14 and 0.88 snails/0.1 m;, respectively. No infected snails were found. Conclusion Generally, schistosomiasis endemic in Guichi District tends to decrease, yet the risk of transmission still exists.The findings suggest that the surveillance system on schistosomiasis still needs perfecting, and the sensitivity and level of surveillance should be improved in order to prevent resurgence of schistosomiasis.
