The White House has adjusted its COVID-19 prevention announcement to emphasize the role that indoor air quality plays, a step that many experts say was long overdue, Washington Post reported March 29th.
The White House Office of Science and Technology Policy hosted one virtual discussion March on the need to improve indoor air quality in schools, businesses and homes to reduce COVID-19 infection. The discussion came six days after the head of the office, Alondra Nelson, PhD, wrote one blog postswhich recognizes that the virus is most often transmitted via small airborne particles that can travel long distances and remain in the air for hours.
The CDC, the World Health Organization and other health groups had initially maintained that coronavirus spread primarily via large droplets that fell to the ground within a few feet of the person expelling them, according to Post.
Researchers praised the White House’s focus on air quality, but expressed frustration over its timing.
“We should have done it sooner,” Linsey Marr, PhD, an airborne virus expert at Virginia Tech in Blacksburg, told the publication. “But as for this effort led by the White House, it’s better late than never.”
