According to a University of Minnesota study published in February in the journal Physics of Fluid, adding preventative measures to a restaurant’s setup could limit the transmission of COVID indoors. Specifically, using a predictive model, the researchers found that increasing the filtration capacity of the restaurant’s air conditioning could help reduce the amount of circulating virus in the air. Additionally, adding shields underneath the tables at which diners are eating could reduce air currents potentially carrying COVID-infected respiratory droplets throughout the space. “Our work highlights the need for more preventive measures” to ensure diner safety, study author Jiarong Hong, an associate professor in the University of Minnesota’s College of Science and Engineering, said in a statement. That’s not the only means by which eating at a restaurant can be made safer, however.

While the cold weather may make outdoor dining seem like a less appealing prospect than eating indoors, it’s worth it to avoid COVID—so head to that heated patio or covered deck. According to the CDC, you should ideally eat outdoors whenever possible, including in tents with open doors or sides that have been retracted. “You are less likely to get or spread COVID-19 during outdoor activities,” the public health agency explains.

While no one would expect you to keep your mask on during your meal, it should cover your mouth and nose any time you’re not eating or drinking, the CDC says. The same goes for servers, who should be wearing masks throughout their shift and changing them if they touch them or otherwise get them dirty.

The CDC recommends staying six feet away from anyone who’s not a member of your household when you’re dining out, whether indoors or outdoors. In fact, White House chief medical adviser Anthony Fauci, MD, says that social distancing is the only way to keep indoor dining safe. “If you do indoor dining, you do it in a spaced way where you don’t have people sitting right next to each other,” Fauci told Don Lemon during a Feb. 2 CNN interview. Hand hygiene is one of the easiest—and most important—ways to limit COVID transmission, especially in shared spaces, like restaurants. The CDC suggests washing your hands with soap and water for at least 20 seconds before you eat and before you leave the restaurant, or using hand sanitizer made from at least 60 percent alcohol.

Longer exposure to other people—especially when unmasked and indoors—can increase your risk of catching COVID from someone else. That’s why the CDC suggests keeping any visit to a restaurant as brief as possible, so don’t stick around to chat when your meal is over—and maybe take that dessert to go.
