Such factors have allowed the colonization of new areas by vectors, mainly Aedes aegypti, which can be found in 80% of the Brazilian territory.^,

Chikungunya, whose virus originated in Africa, succeeded the dengue fever in Brazil in 2014, with similar clinical and laboratory presentation, hindering the differential diagnosis. In 2015, the first cases of zika were reported in Brazil. summarizes the clinical manifestations of those arboviral diseases.^–
