- An MIT study showed that people who maintain 60 feet of distance from others indoors are no more protected than if they socially distanced by just 6 feet.
- According to the researchers, other calculations of the risk of indoor transmission have omitted too many factors to accurately quantify that risk.
- “We need scientific information conveyed to the public in a way that is not just fear mongering but is actually based in analysis,” the author of the study said.
The risk of being exposed to Covid-19 indoors is as great at 60 feet as it is at 6 feet — even when wearing a mask, according to a new study by Massachusetts Institute of Technology researchers who challenge social distancing guidelines adopted across the world.
MIT professors Martin Z. Bazant, who teaches chemical engineering and applied mathematics, and John W.M. Bush, who teaches applied mathematics, developed a method of calculating exposure risk to Covid-19 in an indoor setting that factors in a variety of issues that could affect transmission, including the amount of time spent inside, air filtration and circulation, immunization, variant strains, mask use, and even respiratory activity such as breathing, eating, speaking or singing.
