目的监测血吸虫病传播控制后的疫情动态,为制定防治策略提供科学依据,巩固达标成果,为实现血吸虫病传播阻断打下坚实基础。方法在感染季节后,对565岁人群采用血清学方法进行筛查;对血清学阳性者进行病原学检查,同时开展耕牛和钉螺调查。结果人群调查12745人,血检阳性1094人,粪检1084人,粪检阳性22人,感染率为0.17%;耕牛调查862头,阳性0头;钉螺调查面积1886850m2,查出有螺面积27440m2,解剖钉螺604只,感染性钉螺0只。结论西昌市达到血吸虫病传播控制标准后疫情稳定,要继续加大防治力度,巩固传播控制成果,实现传播阻断的目标。
Objective To monitor the epidemic situation of schistosomiasis transmission control and provide a scientific basis for the formulation of prevention and control strategies to consolidate the achievement of the standard and lay a solid foundation for the realization of schistosomiasis transmission. Methods After the seasons of infection, a serological method was used to screen the 565-year-old population. The seropositive patients were tested for pathogenicity and cattle and snails were investigated simultaneously. Results A total of 12745 people were investigated in the population, 1094 were positive for blood tests, 1084 for dung, 22 were positive for stool infection, and the infection rate was 0.17%. 862 cattle were surveyed and 0 were positive; snail survey area was 1886850m2, and snail area was 27440m2 604 dissected snails, 0 infective snails. Conclusion Xichang City reached the standard of transmission control of schistosomiasis after the epidemic was stable, we must continue to increase prevention and control efforts to consolidate the spread of control results, to achieve the goal of blocking transmission.
