Experts Say 20 Ft to prevent airborne infection.

Experts Say 20 Ft to prevent airborne infection.

"Richard Corsi, a Portland State University dean, has studied the spread of COVID-19 through both large and tiny droplets in the air and recommends people stay 20 feet away from each other when they’re outdoors"

What do he and a small group of aerosol science colleagues across the nation think about the 6-foot social distancing advisory from the U.S. Centers for Disease Control and Prevention? “It’s just been driving us nuts,” Corsi said. “I don’t think we’re being safe enough,” he said. “People need to understand that the airborne route, that’s a serious transmission pathway.”

If an oncoming hiker coughs just before you pass, “you’re probably walking through a cloud of viruses that stay suspended in air,” Corsi said.
