A year ago, if you saw someone wearing a mask, you might assume they were sick or maybe even a little weird or paranoid. Today, thanks to the pandemic, wearing a mask to prevent the spread of COVID-19 is the new normal for many Americans.Thirty-four states and the District of Columbia require people to FILE – Surgeon General Dr. Jerome Adams, left, bumps elbows at Sergio’s Restaurant in Doral, Florida, July 23, 2020.Not all Americans have adopted mask-wearing, especially not those who view masks through a political lens. But pandemics have changed public habits in the past. Wearing a face covering is much more common in East Asia since the outbreak of FILE – Barbers Johnny ‘Geo’ Sanchez, left, and Alberto Sagentin, rear, cut hair in the Little Havana neighborhood of Miami, May 21, 2020.“I can see how, in the future, especially during the cold and flu seasons, people are going to step away from it saying, ‘Hey, listen, let’s just wave, let’s bow to each other, let’s do a namaste. Let’s do something different,” he says. “So yeah, I think there’s going to be a cultural shift with the handshake.”Overall, Americans might be less touchy-feely, according to Dr. Aaron Glatt, spokesperson for the FILE – A shopper wears a mask and gloves to protect against coronavirus as he shops at a grocery store in Mount Prospect, Illinois, May 13, 2020.“When you go through something like a pandemic, regardless of how you feel politically, it is a fairly scary and unpredictable event. And I do feel like certain habits that we’ve picked up, like hygiene habits, are likely to stick on some level of moving forward,” says Mathema of Columbia University.“Some of these habits that we’ve learned, like washing our hands, including mask-wearing, for that matter, disinfecting surfaces, some of these habits will likely sort of continue on,” he says.And that could be one of the pandemic’s silver linings.“I think there’s a heightened sense of awareness of how certain illnesses can be spread,” says Glatt of IDSA. “People won’t accept … uncleanliness or poor hygiene, and they may wipe things down where in the past they would have not thought to do so. They may be a little bit more careful washing their hands.”Industries might also change. More businesses have gone paperless and contactless during the pandemic; there are fewer receipts to sign, restaurants have dropped paper menus, and airlines have new cleaning and air filtration standards.“I see that being the more important component, where the service side of the world is basically going to say, ‘We learned that cleanliness is important, that disinfection is important, and we’ll continue doing that in the workplace,’” says Lushniak of the University of Maryland. “It’s those types of practices that I think people will be looking for and, in fact, specific industries may be advertising, saying, ‘Hey, we do it this way, why don’t you come into our place versus some other place?’”FILE – Hand sanitizer sits on a cart as Des Moines Public Schools custodian Tracy Harris cleans a chair at Brubaker Elementary School, July 8, 2020, in Des Moines, Iowa.Another long-term impact of the pandemic could be more people staying at home when they are sick.“What we’ve learned about here is the beauty of, not in everybody’s circumstance, but the world of telework has really opened up new opportunities for us to say, ‘Listen, you know, right now I’m not feeling well.’ It used to be that that was always a sign of weakness,” Lushniak says.In a post-pandemic world, staying home might be more likely to be viewed as a courtesy to fellow commuters and coworkers, and an effort to stop the spread of disease.
