多年来,基层血防工作不同程度地忽视了外来流动人口这一特殊群体,致使不断有外来人员感染血吸虫病的报道[1]。长江中下游作为我国血吸虫病重点流行区域,近年来疫情有再度回升的趋势,部分地区钉螺面积,尤其是阳性螺面积未能得到有效控制[2]。随着经济大开发战略的实施,此类地区涌入大量流动人口。他们为社会的弱势群体,与城市居民面临着同样的公共卫生问题[3]。他们中有相当一部分来自非疫区,即使来自疫区,也大都因血防宣传教育力度不够,缺乏对血吸虫病知识的掌握,防治意识淡薄,又因生产、生活需要接触疫水机会频繁,使得他们成为感染的高危人群。在这种背景下,血防管理有必要在完善现有体制的基础上,继续调整工作思路,在有效遏制本地居民感染的同时,建立和完善基层流动人口的血防管理机制,避免疫情的死灰复燃。
Over the years, grassroots blood and blood defenses have, to varying degrees, neglected the special group of migrants, resulting in the continuous reports of infection by foreign workers against schistosomiasis [1]. As the epidemic area of schistosomiasis in the middle and lower reaches of the Yangtze River, the epidemic has risen again in recent years. The area of snails in some areas, especially the positive spiral area, has not been effectively controlled [2]. With the implementation of the economic development strategy, a large number of floating population have been infused into such areas. They are vulnerable groups in society and face the same public health problems as urban dwellers [3]. A large proportion of them are from pest free areas, even though they are from endemic areas due to inadequate prevention and treatment of public health education, lack of mastery of schistosomiasis knowledge, weak awareness of prevention and treatment, and frequent opportunities for contact with infected water due to their production and living needs, Become infected at high risk. Against this background, it is necessary to continue to readjust the work train of thought on the basis of improving the existing system of blood-borne disease prevention. While effectively curbing the infection among local residents, we must establish and improve a blood-disease prevention and management mechanism for the floating population at the grass-roots level so as to avoid the resurgence of the epidemic.
