摘要
目的比较南京市血吸虫病防治策略调整前后的防治效果,为完善血吸虫病防控策略提供依据。方法收集1993—2018年南京市人畜血吸虫病疫情、螺情和哨鼠感染监测资料,比较血吸虫病防治策略调整前(1993—2004年)后(2005—2018年)南京市人畜血吸虫病阳性率、哨鼠阳性率、钉螺阳性率、钉螺面积、感染性钉螺面积和灭螺面积,评价防治策略调整前后的实施效果。结果南京市血吸虫病防治策略调整后,人群血吸虫病阳性率分别为0.77%和0.02%,家畜血吸虫病阳性率分别为0.46%和0.01%,钉螺阳性率分别为0.19%和0.11%,哨鼠阳性率分别为34.35%和1.56%,差异均有统计学意义(χ^(2)=6430.634、344.401、239.685和1856.286,均P<0.001);钉螺面积M(QR)分别为4175.37(1301.65)hm^(2)和2366.44(885.27)hm^(2),感染性钉螺面积M(QR)分别为870.49(1001.75)hm2和0(158.89)hm^(2),灭螺面积M(QR)分别为1383.23(793.57)hm^(2)和5031.94(629.11)hm^(2),差异均有统计学意义(Z=-3.755,-3.654和-4.320,均P<0.001)。结论南京市调整血吸虫病防治策略后,血吸虫病防治效果显著,达到了血吸虫病传播阻断标准;应继续实施并完善综合防治策略,消除血吸虫病。
Objective To compare the effectiveness before and after the adjustment of schistosomiasis control strategies in Nanjing City,so as to provide the evidence for improving schistosomiasis control interventions.Methods The preva⁃lence of Schistosomasis japonicum infections in humans,livestock,Oncomelania hupensis and sentinel mice was collected in Nanjing City from 1993 to 2018,and the prevalence of S.japonicum infections in humans,livestock,sentinel mice and O.hupensis,and the areas of snail habitats,areas of infected snail habitats and snail control areas were compared before(1993-2004)and after(2005-2018)the adjustment of schistosomiasis control strategies to evaluate the effective⁃ness.Results The prevalence of S.japonicum infections in humans,livestock,O.hupensis and sentinel mice was 0.77%and 0.02%(χ^(2)=6430.634,P<0.001),0.46%and 0.01%(χ^(2)=344.401,P<0.001),0.19%and 0.11%(χ^(2)=239.685,P<0.001),and 34.35%and 1.56%(χ^(2)=1856.286,P<0.001)in Nanjing City before and after the adjustment of schisto⁃somiasis control strategies,respectively.The median areas(interquartile range)of snail habitats,infected snail habitats and snail control were 4175.37(1301.65)and 2366.44(885.27)hm^(2)(Z=-3.755,P<0.001),870.49(1001.75)and 0(158.89)hm^(2)(Z=-3.654,P<0.001)and 1383.23(793.57)and 5031.94(629.11)hm^(2)(Z=-4.320,P<0.001)in Nanjing City before and after the adjustment of schistosomiasis control strategies,respectively.Conclusions After the adjust⁃ment of schistosomiasis control strategies,remarkable effects on schistosomiasis control has achieved in Nanjing City,where the transmission of schistosomiasis was interrupted.Nevertheless,the strategy requires to be continued and im⁃proved to move towards elimination of schistosomiasis in Nanjing City.
