巴西是一个热带大国（8，514，215平方公里），有185，360，000婴儿。其领土的三分之一以上为热带森林或其他自然生态系统所覆盖。这些为许多虫媒病毒的存在提供了理想的条件，这些虫媒病毒在各种各样的人畜共患病循环中得以维持。巴西可能出现新的虫媒病毒的风险与存在人口稠密的大城市有关，这些城市受到库蚊和高度嗜热的埃及伊蚊等蚊子的侵扰。受感染的人或动物可能来自发生虫媒病毒人畜共患病的生态-流行病学环境。本研究分析了甲病毒马亚罗，委内瑞拉马脑炎，东部马脑炎和基孔肯雅;黄病毒黄热病，Rocio，圣刘易斯脑炎和西尼罗河，和奥博本扬病毒奥罗波什出现的风险。
Brazil is a large tropical country (8,514,215km(2)) with 185,360,000 inbabitants. More than one third of its territory is covered by tropical forests or other natural ecosystems. These provide ideal conditions for the existence of many arboviruses, which are maintained in a large variety of zoonotic cycles. The risk that new arboviruses might emerge in Brazil is related to the existence of large, densely populated cities that are infested by mosquitoes such as Culex and the highly anthropophilic Aedes aegypti. Infected humans or animals may come into these cities from ecological-epidemiological settings where arbovirus zoonoses occur. This study analyzes the risk of emergence of the alphaviruses Mayaro, Venezuelan equine encephalitis, Eastern equine encephalitis and Chikungunya; the flaviviruses yellow fever, Rocio, Saint Louis encephalitis and West Nile, and the ortbobunyavirus Oropouche.
