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

ABSTRACT

SUMMARY 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. RESULTS: Initially, 20 articles were selected and then reduced to 19 after exclusion based on repetititve articles. Titles and abstracts were analyzed, and 14 articles were excluded because they did not meet the inclusion criteria and did not answer the guiding question. Studies show that patients receiving certain medications in the initial stages (one and two) indicate a reversal of complications during hospitalization or often do not require hospitalization in addition to being discharged in a shorter period of time. CONCLUSION: Studies have reported that effective drugs for treating COVID-19 exist. In addition, this study emphasizes the importance of performing therapeutic interventions in the initial stages of infection aimed at reversing the disease and minimizing public health costs.
