"It is pushing strategies, such as better air filters in schools and businesses, to help curb the spread of the virus"
"The White House is pivoting to emphasize that poorly ventilated indoor air poses the biggest risk for coronavirus infections, urging schools, businesses and homeowners to take steps to boost air quality — a move scientists say is long overdue and will help stave off future outbreaks.
“Let’s Clear the Air on COVID,” a virtual event hosted Tuesday by the White House science office, came after President Biden’s coronavirus response team and other leaders have elevated warnings that airborne transmission is the primary conduit of coronavirus infections, a reversal of earlier federal guidance.
“The most common way COVID-19 is transmitted from one person to another is through tiny airborne particles of the virus hanging in indoor air for minutes or hours after an infected person has been there,” Alondra Nelson, head of the White House Office of Science and Technology Policy, wrote in a blog post last week. “While there are various strategies for avoiding breathing that air — from remote work to masking — we can and should talk more about how to make indoor environments safer by filtering or cleaning air.”"
