In some specific areas, the US does not recommend traveling under any circumstances (alert level 4): favelas in general and the satellite cities of Brasilia such as Ceilandia, Santa Maria, São Sebastião and Paranoa during the night.
It also recommends not traveling to areas 150 kilometers or closer to the borders of Brazil with Venezuela, Colombia, Peru, Bolivia, Guyana, Suriname, French Guiana and Paraguay.
This recommendation does not apply to the national parks of Iguazu and Pantanal, bordering with Argentina and Paraguay and with Bolivia and Paraguay, respectively, and which are considered safe.
Regarding the favelas, the US Government says that “neither the police nor the local authorities” consider them safe and that the situation can change quickly and without prior notice.
The caution also extends to areas near these informal neighborhoods, since “occasionally, fighting between the gangs and with the police exceeds the boundaries of the communities.”
The statement highlights that in Brazil, “violent crimes such as murder, armed robbery and vehicle theft are common in urban areas, day and night.”
US Government officials are also recommended not to use municipal public buses in all parts of Brazil, due to the risk of assaults and attacks at any time of day.
Among the list of recommendations to tourists who in spite of everything want to travel to Brazil, the US Government cites being careful in isolated areas, not walking on the beach at dusk, not displaying signs of wealth such as expensive watches or jewels, being alert in banks and ATMs and be careful in public transport.
