Currently, randomized controlled trials have not shown any specific antiviral treatment to be effective for COVID-19. Therefore, treatment is based on symptomatic and supportive care, with intensive care measures for the most severe cases (22). However, many forms of specific treatment are being tried, with various results, such as with remdesivir, lopinavir/ritonavir, chloroquine phosphate, convalescent plasma from patients who have recovered from COVID-19, and others (23-26).
