Abstract
Pandemics like the one currently faced with the Coronavirus (SARS-CoV-2; COVID-19) are characterized as infectious diseases that spread over large geographic regions, practically at the same time, in several countries. The pandemic emerged in the city of Wuhan in China and is believed to be related to the trade and ingestion of wild animals; however, there is uncertainty about various aspects of COVID-19's origin history, including which species have passed it on to a human being. SARS-CoV-2 is part of the beta-coronaviruses family that also includes SARS-CoV, both responsible for Severe Acute Respiratory Syndrome, and MERS-CoV, Middle East Respiratory Syndrome. Although there is a similarity, understanding the natural history of COVID-19 is essential to determine the possibilities of intervention, prognosis and course of the disease; however, data are extremely scarce, and the publications available are recent and still controversial.
