Oregon COVID-19 updates July 21: Expert says wear masks outdoors unless 15-20 feet from others

“The guidelines in Oregon and Washington include wearing a mask, even outdoors, if you can't socially distance 6 feet from others. But an air quality expert at Portland State University suggests people wear face coverings unless they are 15-20 feet away from other people.“

Masks outdoors: Expert says wear them unless you're 15-20 feet away from people

“While there has been documented transmission from outdoor large gatherings, it appears to be much lower than indoors," said Dr. Richard Corsi, an air quality expert at Portland State University. "But there's still a risk."

Corsi said the main concern with crowds is close-contact transmission and sometimes 6 feet might not even be enough.

"If the wind is blowing in the right direction and someone's speaking from 15 feet away and a large droplet comes out of their mouth and the wind is blowing in the right direction, that can reach you," he explained.”
