本文阐述了当前我国大山区血吸虫病的流行情况及防治现状,对今后的防治策略进行了讨论。在钉螺分布广、灭螺难度大、又不易调动劳动力进行防治工作的情况下,大山区防治血吸虫病的策略似应作适当调整。由于近年来治疗药物和查病方法的改进,大山区血吸虫病流行区又大都呈局灶性分布,人群流动少,钉螺分布呈单元性,野生动物在大山区血吸虫病流行中的意义不大,可以把病人和病畜的化疗作为防治重点。近几年大山区防治血吸虫病研究试点资料表明:应用吡喹酮反复治疗病人、病畜,可以大幅度降低人群和家畜的感染率,从而有可能达到控制血吸虫病。在消灭传染源的同时,还应消灭易感地带的钉螺:对有螺无病地区的钉螺,可进行定期监测。
This article describes the prevalence and prevention and cure status of schistosomiasis in the current mountainous areas in China and discusses the prevention and treatment strategies in the future. In snails widely distributed, snail difficult, it is not easy to mobilize the workforce to prevent and control work, the strategy of preventing and treating schistosomiasis in the mountainous areas should be appropriately adjusted. Due to the improvement of therapies and disease-finding methods in recent years, the prevalence of schistosomiasis in the mountainous area is mostly focal distribution. The population flow is small and snail distribution is unitary. The significance of wildlife in the epidemic of schistosomiasis in the mountainous area is not obvious, Chemotherapy of patients and sick animals can be the focus of prevention and treatment. In recent years, experimental data on the prevention and treatment of schistosomiasis in mountainous areas show that repeated treatment of patients and sick animals with praziquantel can greatly reduce the infection rate of the population and livestock and make it possible to control schistosomiasis. In addition to eliminating sources of infection, it should also eliminate snails in susceptible areas: Regular surveillance can be carried out on snails with snails and disease-free areas.
