随着我国经济改革形势的发展,流动人口逐渐增多。由于人口流动引起疟疾流行而造成的危害日趋突出。我县在1978年以前,连续十多年疟疾发病率稳定控制在万分之一以下,1978年以后,由于大量的外地民工流入我县修路和砍伐树木,连续五年发生疟疾流行;1983年在局部地区还发生了疟疾暴发流行,疟疾发病率达19.8％,原虫率11.4％。1934年以后,我县通过加强对流动人口疟疾管理,不但很快控 With the development of China’s economic reforms, the number of floating population has gradually increased. The harm caused by the malaria epidemic caused by population movements has become increasingly prominent. Before 1978, the county’s incidence of malaria was steadily controlled at less than 1/10,000 for more than ten consecutive years. Since 1978, malaria was endemic for five consecutive years due to a large number of foreign migrant workers who flowed into roads and felled trees in our county; 1983 Malaria outbreaks have also occurred in local areas, with an incidence of 19.8% for malaria and 11.4% for protozoa. After 1934, the county not only controlled the malaria control of the mobile population.
