Abstract

Objective: To describe the Oropouche virus and its epidemiological context in the Amazon between the years 2009 to 2019. Methods: This work is a study of a systematic review of the qualitative meta-synthesis type from an epidemiological perspective where the survey of the material was carried out through research on platforms search engine using keywords such as “Oropouche,” “Oropouche virus,” “Oropouche Virus and Amazon”. Results: The Oropouche virus (VORO) is an arbovirus that belongs to the family Peribunyaviridae, genus Orthobunyavirus. Its first isolate occurred in 1955, in Brazil the virus was the first isolated in 1960 and the Amazon has so far been the site most affected by this arbovirus. The main clinical features are fever, headache, and body aches, and because of these symptoms easily confused with other arboviruses like Dengue and Zika. Due to the lack of information and its clinical similarity with other arboviruses, its diagnosis, both clinical and laboratory, becomes complex. Final considerations: Given the current situation of the Oropouche virus in the world, but mainly in Latin America, it is possible to observe that a silent expansion is taking the place of this virus due to the difficulty of research and identification of patients who are genuinely positive for this virus.
