We are at yet another crossroads in the pandemic. It’s a race to see how many people can get vaccinated before new variants start to spread widely. Richard Corsi is an indoor air quality expert and dean of the College of Engineering and Computer Science at Portland State University. He says public health messaging has focused too heavily on sanitizing surfaces and not enough on preventing the way the coronavirus spreads through the air. He says it’s ventilation that’s going to be key in preventing another spike in cases.
