Most people aren’t going to wear a mask forever, even if viruses remain a persistent threat. What we now know is that respiratory viruses are transmitted mostly through the air, mostly indoors, and mostly in badly ventilated buildings. I talk with Harvard Professor Joseph Allen about a new normal that makes sense. It’s okay, he says, that vaccinated people are putting their masks back in the drawer. It’s not okay that so many of us live and work in “sick” buildings. There’s no downside to healthy buildings – they not only help keep people from getting covid, colds and flu, they can also help us feel more energetic and think more clearly.
