There have been 4 waves of imported malaria in the USA. They occurred during the colonization of the country and during the Second World War, the UN Police Action in Korea, and the Viet-Nam conflict. The first 3 episodes are briefly described and the data on imported malaria from Viet-Nam are discussed in detail.Endemic malaria is resurgent in many tropical countries and international travel is also on the rise. This increases the likelihood of malaria being imported from an endemic area and introduced into a receptive area. The best defence for countries threatened by imported malaria is a vigorous surveillance programme. The principles of surveillance are discussed and an example of their application is provided by a description of the methods used to conduct surveillance of malaria in the USA.
美国曾出现过4波输入性疟疾疫情。它们分别发生在该国殖民时期、第二次世界大战期间、联合国在朝鲜的警察行动以及越南冲突期间。简要描述了前三起事件，并详细讨论了来自越南的输入性疟疾数据。许多热带国家的地方性疟疾正在卷土重来，国际旅行也在增加。这增加了疟疾从流行地区输入并传入易感地区的可能性。对于受到输入性疟疾威胁的国家来说，最佳防御措施是实施强有力的监测计划。讨论了监测原则，并通过描述美国用于开展疟疾监测的方法为例，说明了这些原则的应用。
