Epidemiological studies were conducted on malaria in three rural areas of the Amazon basin in the State of Rondônia: the town of Costa Marques, Forte Principe da Beira (Fort), and an immigrant settlement in the nearby forest. These studies were instituted to document the malaria problem and to describe the role of immigration on its distribution and prevalence. Hospital records in the town show that the number of malaria cases increased five fold from 1983 to 1987 and that the predominant malaria parasite changed from Plasmodium vivax to P. falciparum. Increased malaria followed increased immigration and colonization of the forest. A series of epidemiologic studies suggested the linkage between malaria and immigration as the prevalence of malaria was 1-2% at the Fort, a stable community, 8-9% at Costa Marques, a growing community, and 14-26% in the new settlements in the forest.
在朗多尼亚州亚马逊流域的三个农村地区开展了疟疾流行病学研究，这三个地区分别是：科斯塔·马克斯镇、贝拉王子堡（简称“堡”）以及附近森林中的一个移民定居点。开展这些研究旨在记录疟疾问题，并描述移民在疟疾分布和流行方面所起的作用。该镇的医院记录显示，从1983年到1987年，疟疾病例数量增长了五倍，而且主要的疟原虫已从间日疟原虫转变为恶性疟原虫。疟疾增加是随着森林地区移民和殖民化的增加而出现的。一系列流行病学研究表明了疟疾与移民之间的联系，因为在稳定社区“堡”，疟疾患病率为1%-2%，在发展中社区科斯塔·马克斯为8%-9%，而在森林中的新定居点则为14%-26%。
