Human movement especially associated with major events can facilitate the transmission and spread of pathogens through importation by visitors in the host country or exportation of endemic pathogens to the countries of origin of visitors when returning home. The current scenario in Brazil is of a triple epidemic of Dengue, Chikungunya and Zika, including in the state of Rio de Janeiro, local headquarters of the Olympic Games which occurred in August, 2016. The complications arising from infections by Zika as microcephaly and Guillain-Barré syndrome, dengue and Chikugunya morbidity frames preoccupied participating countries as well as tourists who  took part of the event. However, the possibility of introducing new non-current arboviruses in Brazil should be considered a risk factor, once the country has conditions to maintain and propagate new arboviruses, for both the vector and susceptible population, as occurred with the rapid dissemination of Chikungunya and Zika viruses.
