"What they revealed is masks can also help reduce the inhalation of droplets by the wearer, and in fact they went on to say that cloth masks, particularly multiple layers of cloth masks, are as effective as surgical and medical grade masks for doing just that," said Karen Ayala, DuPage County Health Department.
Among the seven studies cited by the agency was that of a hair salon in Springfield, Mo., were in May two COVID-19 symptomatic stylists interacted for an average of 15 minutes with 139 clients over an eight day period.

"Part of what I think we're hoping here is that if people shift the way they're looking, as opposed to thinking I'm wearing a mask 'cause if I'm sick, I'm protecting someone else, but I'm not sick so I don't have to worry about it, they'll start thinking wow, this is actually going to help me as well," said Dr. Nimmi Rajagopal, Cook County Health.
With coronavirus cases soaring across the country and Americans being driven indoors by cooler temperatures and the upcoming holiday season, it is the hope of local health officials that this updated guidance motivates those who have so far resisted wearing masks on a regular basis to do so.

"We compared counties. One has a masking requirement, the neighboring one does not. We see that the transmission of this virus goes down. We also see that the acuity of illness goes down, and both of those are vitally important," said Ayala.
