Travellers should exercise increased caution in Brazil due to elevated risks of violent crime, including murder, armed robbery, carjacking, and kidnapping. Criminal activity is widespread in urban areas and often linked to organized crime and drug trafficking. Particular caution is advised regarding drink spiking scams, especially in Rio de Janeiro, and when using public transportation or visiting ATMs. Certain areas including informal housing developments (favelas), border regions within 160km of land borders, and specific satellite cities of Brasilia should be avoided entirely due to extreme security risks.
