Experimental Antiviral Treatment for COVID-19

TUESDAY, May 18, 2021 (HealthDay News) — An experimental antiviral treatment for COVID-19 has shown great promise in mice, researchers report.

American and Australian scientists used gene-silencing RNA technology to destroy the virus genome and prevent the virus from replicating, the Washington Post reported.

“These stealth nanoparticles can be delivered to a wide range of lung cells and silence viral genes,” said researcher Nigel McMillan, from Griffith University in Queensland, Australia.

The treatment reduced viral load in mice by 99.9%, according to early results published May 13 in the journal Molecular Therapy.

A number of COVID-19 vaccines are available, but there is no antiviral treatment specifically for the coronavirus that causes COVID-19 that works after people have become infected, the Post reported.

Research shows that some currently available antivirals, such as remdesivir, can shorten hospital stays for COVID-19 patients, but they don’t significantly reduce the risk of death.
