Effectiveness of early therapeutic intervention in phases one and two after COVID-19 infection: systematic review.

Objectives: Although research in relation to new vaccines for the coronavirus, SARS-CoV-2 (COVID-19), is ongoing, it has been reported that medical teams are also considering the use of antiviral drugs in patients in order to verify their effectiveness when infection signs and symptoms present, mainly in stages one and two of the disease.

Methods: For the selection of studies, the combination based on the Medical Subject Heading Terms (MeSH) was used, and the databases Medline (Pubmed), LILACS, SciELO, SCOPUS, Web of Science, and BIREME were searched. The search period for articles consisted of manuscripts published between January 2010 and July 2020 without language and localization restrictions.
