Antivirals can definitely play a role in management of Covid-19 patients. The only 2 drugs with randomised trials so far are Interferon and Remdesivir. Interferon should be given before 7 days of symptom onset. The very few patients that do not recover may need tocilizumab which acts against interleukin-6 receptors.Only one injection may be needed. The aircraft carrier Theodore Roosevelt has demonstrated that 60% of infected patients remain asymptomatic, 60% develop antibodies and above all only 1 sailor succumbed out of the 1100 infected.
Hence case fatality rate is less than 0.1% in young and fit sailors. Triple combination of interferon beta-1b, lopinavir–ritonavir, and ribavirin in the treatment of patients admitted to hospital with COVID-19: an open-label, randomised, phase 2 trial
