The spread of SARS-CoV-2 could be slowed by a new antiviral drug

If you have COVID-19 positive before , SARS-CoV-2 has already infected your lungs

Viral shedding occurs with each breath

Existing COVID-19 medicines, even when they relieve symptoms, don't stop viral shedding

Therapeutic interfering particle (TIP), reduces virus excreted by infected animals and restricts virus transmission

TIPs can lower viral shedding in addition to symptoms and viral burden

TIPs did not inhibit COVID-19 transmission when SARS-CoV-2–infected animals were kept with uninfected animals
