Mayaro virus has always been one of the significant challenges for biomedical science, and efforts are aimed at intervening factors preventing viruses from spreading. This letter reviews recent research on emerging zoonotic viruses in Latin America, focusing on Mayaro virus as a new threat. It also considers vector and clinical characteristics and similarities with other arboviruses (arthropod borne), such as Zika virus, dengue virus, and chikungunya virus.
The diseases caused by arboviruses are very serious worldwide, and since their surveillance and prevention requires monitoring of their vectors, their control is difficult, and their expansion to any tropical or subtropical country is almost impossible to avoid.
At the same time, suitable eco-epidemiological conditions of tropical and subtropical regions have allowed the persistence of arboviruses by providing an ideal blend in terms of vector usage and specificity as well as an ample host range. Newly introduced arboviruses in the New World seem to be smoothly transitioning from their epidemic effervescence into endemic levels of transmission, revealing an increased potential for adaptation.
Although these risk factors are taken into account, research indicates that the relationship between these factors and the spread of arboviruses in South America is necessary, but this cannot be the only geographic region affected by these factors.
