摘要
目的评价江苏省预防控制血吸虫病中长期规划防治策略和效果。方法采取以控制钉螺、人畜筛查化疗为主的综合性防治策略，实施预防控制血吸虫病中长期规划，纵向观察、评价防治效果。结果2003--2007年全省灭螺覆盖率和人畜化疗比率逐年增加，钉螺面积、感染性钉螺面积及人畜血吸虫感染率逐年下降。灭螺覆盖率与感染性钉螺面积、感染性钉螺环境数、人群感染率、家畜感染率及急性血吸虫病发生率均呈显著负相关（r与感染螺面积=-0．897，P=0．039；r与歙螺环境=-0．937，P=0．019；r与人群感染率=-0．913，P=0．031；r与家畜感染率=-0．991，P=0．001；r与急性血吸虫病=-0．894，P=0．041）；人、畜化疗比率与感染性钉螺面积均呈显著负相关（r人化疗比率=-0．965，P=0．008；r畜化疗比率=-0．921，P=0．027）；经费增加与人、畜感染率呈显著负相关（r经费和人感染率=-0．897，P=0．039；r经费和畜感染率=-0．971，P=0．006）。多元回归分析表明，人、畜感染率与急性血吸虫病发生率及灭螺覆盖率间均有直线关系。结论以控制钉螺、人畜筛查化疗为主的综合性防治策略效果显著；灭螺和化疗是预防控制血吸虫病最直接有效的措施；防治经费的稳定增加是有效控制和消除血吸虫病的基本保证。
Objective To evaluate the mid-term effectiveness of the medium-and-long-term programme of the prevention and control of schistosomiasis in Jiangsu Province. Methods The programme was carried out in Jiangsu Province and the comprehensive measures relied mainly on snail control, detection and chemotherapy of schistosomiasis for residents and livestock. The mid-term effectiveness of the programme was observed and evaluated longitudinally. Results The coverage rate of snail control areas and the ratio of chemotherapy of schistosomiasis for residents and livestock rose year after year. The snail areas, the infected snail areas and the infection rate of schistosome for residents and livestock reduced year after year. There were negative correlations between the coverage rates of snail control and the infected snail areas, the number of settings with infected snails, the infection rate of schistosome for residents, the infection rate of schistosome for livestock and the morbidity of acute schistosomiasis, respectively （rInfected snail areas = - 0. 897, P= 0. 039 ; rNo. of settings with infected snail =- 0. 937, P = 0. 019; rInfection rate for residents = - 0. 913, P = 0. 031; r Infection rate for livestock = - 0. 991, P = 0. 001 ; rMorbidiry of acute schistosomiasis = - 0. 894, P= 0. 041）. There were negative correlations between the ratio of chemotherapy of schistosomiasis for residents and the infected snail areas, and between the ra- tio of chemotherapy of schistosomiasis for livestock and the infected snail areas （rRatio of chemotherapy for residents = - 0. 965, P = 0. 008 ; rRatio of chermotherapy for livestock = - 0. 921, P = 0. 027）. There were negative correlations between the funds of schistosomiasis control and the infection rate of schistosome for residents livestock, respectively （r Infection rate for residents = - 0. 897, P = 0. 039 ; rInfection rate for liverstock =-0. 971,P=0. 006）. The multiple linear regression analysis showed that there were the linearity relationships between the infection rate of schistosome for residents and the coverage rates of snail control, and between the infection rate of schistosome for livestock and the coverage rates of snail control, and between the morbidity of acute schistosomiasis and the coverage rates of snail control Conclusions The effect of the comprehensive strategy of schistosomiasis control which relies mainly on snail control, detection and chemotherapy of schistosomiasis for residents and livestock are remarkable. The snail control and chemotherapy are effective and immediate. The increased funds would be essential guarantee for control and elimination of schistosomiasis.
