What do we know about how COVID-19 is spread?

Reducing the risk of contracting COVID-19 relies heavily on how well we understand how it spreads. Up until now, a lot of focus has been on transmission by getting too close to the coughs and sneezes of an infected person or by touching infected surfaces. But there’s growing evidence indicating that the coronavirus is more likely an airborne illness, similar to other respiratory diseases, where small particles caused by breathing and talking linger in the air traveling from one person to the next. Scientists say the more we understand the spread, the more safely we can reopen. Montclair State University professor and epidemiologist Stephanie Silvera joins Senior Correspondent Briana Vannozzi to explain.
