Molnupiravir is an antiviral agent that works by combining with viral RNA to stop the virus particles from replicating. If a virus can't replicate it won't be able to infect other cells in the body and the infection won't spread as quickly. Molnupiravir can reduce the severity of viral infections such as COVID-19.
