钩虫病是我国五大寄生虫病之一,分布相当广泛,尤其在淮河及黄河一线以南的广大地区流行甚为普遍、严重;东北、华北以及西北的陕西省的许多地区钩虫的感染也并不低,长期以来是严重危害广大劳动人民身体健康的疾病之一。随着防治工作的开展,一些地区有临床症状的病人数目虽较过去大为减少,但各地感染率下降的幅度一般都不很大。特别是近几年来,许多地方不采用过去行之有效的沼气法或三坑式沉淀密封粪池处理粪便,而使用新鲜粪便进行施肥,使土壤污染(主要是自留地、菜地、棉花地、红薯地和桑树林等),造成人群感染,使各地钩虫感染率有所增高。粪便管理固然是防治工作的首要环节,治疗钩虫病 Hookworm disease is one of the five major parasitic diseases in our country. It is widely distributed, especially in the vast areas south of the Huaihe River and the Yellow River. Infection in many areas of Northeast China, North China and Shaanxi Province in Northwest China is also Not low, has long been one of the diseases that seriously endanger the general health of the working people. With the prevention and treatment work carried out, the number of patients with clinical symptoms in some areas has been greatly reduced compared with the past, but the rate of decrease in infection rates in various places is generally not large. In particular, in recent years, many places have not used the proven biogas method or tri-pit sedimentation septic tank to treat manure. Instead, they use fresh manure to fertilize soil and pollute the soil (mainly from reserved land, vegetable fields, cotton fields, sweet potatoes And mulberry trees, etc.), resulting in population infection, so that around the hookworm infection rates have increased. Excrement management is of primary importance in prevention and treatment of hookworm disease
