Yellow fever: recurrent outbreak in the southeast region of Brazil, 2016 - 2020

Abstract

This review article aims to analyze studies that address yellow fever in the southeastern region, since there was a high recurrence of this ancient disease today, from the wild cycle of this virus, which is transmitted by mosquitoes such as the Haemagogus and Sabethes. Database studies such as Google academic, PUBMED, SciELO, books and portals were used. In addition, the inclusion criteria were publications made in the last 5 years that deal with the characteristics of the disease or that analyzed the periodic outbreaks that occurred in southeastern Brazil, such as that of 2016/2017, which was a major outbreak of yellow fever in Brazil, in which a possible cause was government negligence, since before 2017 the vaccine was only available to residents or visitors from endemic regions, such as the Amazonian territory. Thus, it was observed that yellow fever, despite being an enzootic disease (present in certain locations), probably migrated to the southeast from the central-west region, since it borders both areas and therefore deserves an increased attention from health surveillance, as it is possible to prevent possible outbreaks.
