I got an email from my doctor with an update on how they are dealing with the huge uptick in Covid-19 infections. The email had a link to an article about what to do for inviting others over for Thanksgiving. From my email:

With COVID-19 increasing, it's more important than ever to tread carefully this holiday season.

Dr. Thomas Russo, division chief of infectious diseases at UBMD Internal Medicine, spoke with MSN about how to stay safe this year and protect you and your loved ones from COVID-19.

Should I wear a mask at home?

By now it’s second nature to slip our masks on when walking out the door, but when to wear a mask in the safety of our own homes is a little less clear cut. So TODAY tapped the experts to find out whether we should be wearing masks at home this fall and winter. And it turns out that there are two circumstances where infectious disease experts definitely recommend doing it.

When anyone who doesn’t live with you comes over

“Whenever you have someone who is coming into your home that's not a member of your immediate household, they should wear a mask, you should wear a mask, you and whoever else is in the house should wear the mask,” says Soniya Gandhi, MD, associate chief medical officer, Cedars-Sinai/Marina Del Rey Hospital. “You don't know if that person is infectious — people can be asymptomatic and can still transmit the virus. Wearing masks and maintaining as much physical distance as possible when somebody is coming into your home are the cornerstones of trying to mitigate the risk of transmission.”

The right kind of mask helps as well, says Thomas A. Russo, chief of the division of infectious diseases at the University at Buffalo Jacobs School of Medicine and Biomedical Sciences. “Either a N95, surgical mask or well-fitting multilayered cloth mask — no bandanas, no scarves, no gators and definitely no masks with valves, because those valves are just one-way valves, so they protect the wearer but the stuff that they breathe out is not filtered, so if they were infectious they’d just be spewing stuff on you,” Russo explains.

Theoretically, if you’re both wearing well-fitting masks (snugly over the nose and mouth, extending over your chin, and fitting snugly on the face) the entire time and neither of you drop the mask, your risk of contracting COVID from a home visitor is relatively low, says Russo.

This recommendation extends to friends and family who don’t live with you, says Gandhi. “There's an assumption that because people are family outside of your immediate household, that maybe you somehow have less risk. That's unfortunately just not true,” she says.

The good news is, if masks are worn properly, Russo says you can probably take your mask off soon after they leave. “If you're very vulnerable, want to be very conservative, are nervous about imperfect mask usage, and you're living in a place that isn’t optimally ventilated, you could consider wearing your mask for 30 minutes after they leave,” he suggests.
