The early guidance from health experts emphasized washing hands and keeping six feet from others with no recommendation to wear masks or avoid gathering indoors.

Linsey Marr, an aerosols expert and professor of civil and environmental engineering at Virginia Tech, became convinced that advice was based on a flawed idea of how respiratory viruses spread.

That work helped lead to a course correction in the public health guidelines and likely saved lives....
