The key role of antivirals in COVID-19 treatment

A few weeks after the SARS-CoV-2 was identified by Chinese researchers as the cause of ‘COVID-19’, an antiviral called remdesivir, originally used during the 2014 Ebola outbreak, came into play as the first available option to treat patients with coronavirus disease 2019 (COVID-19). Even if the approval process for remdesivir caused some controversy, experts consider the combined use of antivirals and other drugs a promising solution for treatment of Covid-19.
