摘要
目的了解当前扬州市江都区血吸虫病疫情流行态势,为今后防治工作提供科学依据。方法收集2016—2020年江都区螺情、人群病情、家畜病情及哨鼠监测等资料,分析疫情变化情况。结果 2016—2020年江都区累计查螺17 042.85 hm^(2),有螺面积14.54~88.82 hm;活螺框出现率9.90%~14.64%,活螺平均密度0.17~0.61只/0.11 m;累计解剖钉螺20 698只,均为阴性。人群血清学查病90 335人,阳性率0.10%~0.66%,平均阳性率0.40%。其中,流动人口血检平均阳性率高于常住居民,差异有统计学意义(χ^(2)=145.711,P<0.05),而常住居民血检平均阳性率又高于门诊患者,差异有统计学意义(χ^(2)=13.721,P<0.05)。累计开展病原学检查12 397人,未检出阳性。累计开展家畜检查4 048头·次,未发现阳性。结论 "十三五"期间江都区血吸虫病疫情稳定,防治成效显著,但血吸虫病传播风险仍然存在,需继续落实综合防治措施,完善监测预警工作。
Objective To understand the epidemic situation of schistosomiasis in Jiangdu District of Yangzhou City, so as to provide scientific basis for prevention and control of schistosomiasis in following work. Methods The data on the snail, population, livestock and sentinel rat infection were collected in Jiangdu area from 2016 to 2020, and analyzed for the changes of schistosomiasis prevalence. Results From 2016 to 2020, a total of 17 042.85 hm;were surveyed on the snails status in Jiangdu District, where snails area were 14.54-88.82 hm;. The occurrence rate in a typical frame with live snails was between 9.90% and 14.64%, with an average density of 0.17-0.61 snails/0.11 m;. Dissection of 20 698 snails showed no infection. Totally, 90 335 people underwent serological tests, which showed positive rate between0.10% and 0.66%, with average positive rate of 0.40%. The average positive rate by blood test was higher in floating population than those in permanent residents, the difference was statistically significant(χ^(2)=145.711, P<0.05).Serological examination also showed that permanent residents had higher average positive rate than those of outpatients, with statistical difference(χ^(2)=13.721, P<0.05). No schistosomiasis infection was found in a total of 12 397 people received examination of feces, and in a total of 4 048 livestock undergone serological tests. Conclusion Epidemic situation of schistosomiasis remained relatively stable during the 13th Five-Year Plan period in Jiangdu area. The findings suggest that our efforts are remarkable, though the risk of schistosomiasis transmission still exists. Following tasks should involve continuous implementation of comprehensive control measures as well as improvement of monitoring and early warning strategies.
