Good news, Tim. With a little research, you can pick up a suitable mask just in time for the holidays. You can thank me later.
To block a variant this transmissible, scientists say you need an N95 or other high-filtration mask. Here's how to find a good one and when to wear it.

With another coronavirus variant racing across the U.S., once again health authorities are urging people to mask up indoors. Yes, you've heard it all before. But given how contagious omicron is, experts say, it's seriously time to upgrade to an N95 or similar high-filtration respirator when you're in public indoor spaces.
"Cloth masks are not going to cut it with omicron," says
Linsey Marr, a researcher at Virginia Tech who studies how viruses transmit in the air.
Omicron is so much more transmissible than coronavirus variants that have come before it. It spreads at least three times faster than delta. One person is infecting at least three others at a time on average, based on data from other countries.
"It's very contagious," says Dr.
Robert Wachter, chair of the Department of Medicine at the University of California, San Francisco. "And the kind of encounter that you could have had with prior versions of the virus that would have left you uninfected, there's now a good chance you will get infected from it."
