Yunnan Province, due its international borders with Myanmar, Vietnam and Lao PDR has a large number of imported cases of malaria, including a high proportion of Plasmodium falciparum, as a result of the mobility of the population. This movement is due to workers coming from other provinces where there is no malaria to work in the productive tropical lowlands. Chinese nationals who have gone to work in neighboring countries, border trade and refugees from Myanmar. Much of Yunnan is peopled by ethnic minorities living in remote mountainous and forested areas which are difficult to reach. However, surveillance has been strengthened by training 3,900 primary health care workers and combining the search for visiting foreigners, returning Chinese and people from other provinces with public security, customs formalities and employers. Any visitor detected by these services is obliged to have a blood slide taken. This has resulted in an earlier and more complete detection of malaria cases, reducing incidence from 19.19 to 12.12/10,000 in the border area over the last 10 years. This is despite a considerable increase in population movement and the threat of drug resistant malaria.
云南省与缅甸、越南和老挝接壤，由于人口流动，有大量疟疾输入病例，其中恶性疟原虫比例很高。这种人口流动是因为来自其他无疟疾省份的工人到热带低地从事生产工作。包括到邻国工作的中国公民、边境贸易以及来自缅甸的难民。云南大部分地区居住着少数民族，他们生活在偏远山区和森林地区，交通不便。不过，通过培训3900名初级卫生保健工作者，并将对外国访客、回国华人及其他省份人员的排查与公安、海关手续及雇主相结合，加强了监测。这些部门发现的任何访客都必须进行血涂片检查。这使得疟疾病例得以更早、更全面地被发现，过去10年边境地区的发病率从每万人19.19例降至12.12例。尽管人口流动大幅增加且存在耐药疟疾的威胁，但仍实现了这一成果。
