Introduction
Dengue virus (DENV) and chikungunya virus (CHIKV) are arboviruses that cause ongoing epidemics in several countries of Latin America. DENV belongs to the Flaviviridae family and CHIKV is an alphavirus of the Togaviridae family. Both viruses are transmitted by mosquitoes of the genus Aedes (mainly Aedes aegypti and Aedes albopictus) and during the acute phase they may cause similar nonspecific febrile syndromes that can progress to severe or debilitating conditions.,
DENV infection has been endemic in Brazil since the 1980’s. However, CHIKV is an emergent agent. Autochthonous transmission was first detected in September 2014 in the city of Oiapoque, Amapá state. Since then, there have been thousands of autochthonous cases in the country. A total of 38,499 and 277,882 cases of suspected CHIKV infection were reported by the national surveillance system in 2015 and 2016, respectively. In 2017, a total of 185,369 suspected cases were reported until December 9. Ceará (1,271 cases/100,000 inhabitants) and Roraima (789 cases/100,000 inhabitants) have the highest incidence among the Brazilian Federation states. Coinfections with these two viruses have been reported and the overall effect on the heart is still unknown.– There have been some reports of myopericarditis following DENV and CHIKV infection, but this manifestation in coinfected patients is rare and few data are available.–
