人群流动和聚集是引起疟疾扩散和暴发流行的重要原因。随着经济的发展,流动人口日益增多,加剧了疟疾的传播,严重地影响了控制和消灭疟疾的进程,是当前各国疟疾控制规划中面临的普遍而难以解决的问题。 我国自80年代以来,经济建设迅猛发展,伴随而来的是流动人口疟疾问题日趋严重。尤其是在大批劳动力流动的经济特区广东、海南两省以及边境贸易日益活跃的广西和云南省,造成了流动人口疟疾控制的许多困难。疟疾发病率又有所上升。每年进出广东省从事采石、烧砖、基建等工种的流动人口高达数百万至千万人,疟疾逐年增多。1991年广东省疟疾发病人数为 6 072例,因人口流动输入传染源,导致发生52
Mobility and agglomeration of people are the major causes of the spread and outbreak of malaria. With economic development, the increasing number of floating population has exacerbated the spread of malaria and seriously affected the process of control and elimination of malaria. This is a common and unmanageable problem in the current malaria control plans in various countries. Since the 1980s, the rapid development of economic construction in our country has accompanied the worsening problem of malaria in floating population. Especially in the special economic zones SEZ Guangdong and Hainan provinces where migrant labor flows and Guangxi and Yunnan provinces where border trade is increasingly active have caused many difficulties in the control of malaria in floating population. The incidence of malaria has risen again. Every year, millions of migrant workers in Guangdong Province who engage in quarrying, burning bricks and infrastructure have a floating population of over 10 million, and malaria is increasing year by year. In 1991, the number of malaria cases in Guangdong Province was 6,072, causing a source of infection due to population movements, resulting in 52
