Scientists struggle to explain how coronavirus moves through the air
The novel coronavirus, COVID-19, can persist in the air for several hours and be carried 23 to 27 feet by gas clouds produced by coughs and sneezes, several studies suggest.
The novel coronavirus, COVID-19, may remain in the air for several hours and be transported by gas clouds produced by coughs and sneezes from 23 to 27 feet, according to several studies.
But the focus on whether a coronavirus transmission occurs primarily through large or small droplets is misguided, according to Lydia Bourouiba, who studies viral transmission at the Massachusetts Institute of Technology.

Large droplets, expelled by sneezes and coughs, are thought to fall to the ground relatively quickly, which means they can contaminate or infect surfaces and people only within a range of a few feet. Smaller droplets, on the other hand, can become aerosolized and travel farther, or so the thinking goes.

But Bourouiba suggests such delineations aren't helpful. In her paper, published in the Journal of the American Medical Association, she points to research that shows swirling clouds of gas produced by coughs and sneezes can carry a wide range of droplet sizes some two dozen feet 3 away.

"The rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the inefectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote.

Some recent lab experiments - detailed in the New England Journal of Medicine suggest that viral particles can remain in the air for several hours. But what relevance the experiments have to transmission investigations remains unclear. Studies of the real-world spread of the virus suggest COVID-19 can spread rapidly on cruise ships, even with passengers quarantined in their rooms. Researchers suggest lab experiments can help scientists better under stand how the virus might behave in different environments.
