An MIT researcher says that current CDC guidelines for proper social distancing might not be enough to stop coronavirus transmission.
Lydia Bourouiba, an associate professor at MIT who has done extensive research on the dynamics of exhalations, has found that some coughs or sneezes can create a cloud of gas that can travel up to 27 feet.
In an article published last week in the Journal of the American Medical Association, Bourouiba wrote that recent studies have shown that exhalations, sneezes and coughs are not solely made of mucosalivary droplets, “but primarily made of a multiphase turbulent gas (a puff) cloud that entrains ambient air and traps and carries within it clusters of droplets.”
Her research can potentially have implications for measures enacted to control COVID-19 transmission around the world.
The Centers for Disease Control and Prevention calls for six feet of space between individuals as an accepted space to enact social distancing, while the World Health Organization advises on three feet of space between people.
