COVID-19, SARS-CoV-2, Coronavirus, Epidemiology, VirologyAbstract
Six types of coronaviruses were already identified as generators of disease in humans as of 2019, with two previous epidemiological outbreaks standing out: SARS-CoV in 2002 and MERS-CoV in 2012. The new infectious agent that caused the 2019 pandemic was called SARS -CoV-2, which manifests as a severe acute respiratory syndrome (COVID-19). In this regard, on January 30, 2020, the World Health Organization decreed the health emergency. The purpose of this review was to analyze the epidemiological context around SARS-CoV-2 through a bibliographic review in scientific databases such as: PubMed Central, LILACS and Google Scholar. It was concluded that SARS-CoV-2 is highly transmissible, with a fatality rate in Ecuador of 8.59%.
