Is 6 feet enough for social distancing? MIT researcher says droplets carrying virus can travel up to 27 feet
The novel coronavirus has prompted social distancing measures around the world. One researcher believes what's being done isn't enough.
“There’s an urgency in revising the guidelines currently being given by the WHO and the CDC on the needs for protective equipment, particularly for the frontline health care workers,” Bourouiba told USA TODAY. Bourouiba’s research calls for better measures to protect health care workers and, potentially, more distance from infected people who are coughing or sneezing.
Bourouiba argued that a “gaseous cloud” that can carry droplets of all sizes is emitted when a person coughs, sneezes or otherwise exhales. The cloud is only partially mitigated by sneezing or coughing into your elbow, she added. “For me, the question is not how far the germs can travel, but how far can they travel before they’re no longer a threat. The smaller the germ particles, the lower the risk that they might infect somebody who would breathe them in or get them stuck in their nose or their mouth,” Pottinger told USA TODAY.
