Have you ever wondered how an antiviral drug kills a virus? Have you heard of remdesivir and other antivirals in the news and wondered how they might kill SARS-CoV-2? Have you ever wondered why antibiotics are more common than antivirals?    Today, we answer these questions and more in our interview with Dr. Luis Schang, professor of chemical virology at Cornell's Baker Institute for Animal Health. His research focuses on discovering broad-spectrum antiviral drugs, and his lab has recently started to investigate the use of such antivirals to treat SARS-CoV-2.
