目的分析湖北省流动人群哨点监测结果,为湖北省血吸虫病监测与防治提供参考。方法在全省设置哨点,采用血清学检测和粪检对流动人群开展主、被动监测,分析血吸虫病感染情况。结果 2015-2016年,哨点监测流动人群血吸虫病感染率分别为0.02%、0,降幅100%;流动人群血检阳性率分别为1.06%、0.36%,降幅65.55%。两年间,血检阳性者均集中在传播控制和传播阻断有螺地区,2015年监测人群中男性40~岁年龄段血检阳性率最高为1.62%,女性60~岁年龄段最高为1.86%,不同职业间血检阳性率差异均有统计学意义。2015年主、被动监测方式各监测到1例粪检阳性病人,均为男性,40~岁,职业为民工和渔(船)民。结论两年间流动人群血吸虫病疫情指标呈下降趋势,哨点监测对高危人群的筛查起到了作用,应进一步发挥监测哨点的作用。
Objective To analyze the result of sentinel surveillance in floating population in Hubei Province and provide reference for the monitoring and prevention of schistosomiasis in Hubei Province. Methods A sentinel site was set up in the whole province. Serological and fecal tests were used to carry out primary and secondary monitoring of floating population, and the infection status of schistosomiasis was analyzed. Results From 2015 to 2016, the prevalence of schistosomiasis in sentinel monitoring mobile population was 0.02%, 0%, respectively. The positive rates of blood tests in mobile population were 1.06%, 0.36% and 65.55% respectively. In the two years, the blood test positives were concentrated on the transmission control and transmission snail block. In 2015, the highest positive rate of blood test was 40% in males and 1.62% in females at the age of 60 ~ , Different occupational blood test positive rate differences were statistically significant. In 2015, passive monitoring method was used to detect 1 case of positive stool test, all male, aged 40 ~ and employed as migrant workers and fishermen. Conclusions The epidemic index of migratory schistosomiasis is declining in two years. Sentinel surveillance plays a role in the screening of high-risk population, and the role of sentinel surveillance should be further played.
