If you’re the host of the party, keep the guest list as small as you can, ideally just one or two people from outside your household. Alternatively, if you’ve been invited to a party, try to find out how many people will be attending and what size party you would be most comfortable with. Don’t feel pressured to stay for the entire game; Dr. Marr suggested dropping by for the length of a quarter to diminish your exposure to others.
Finally, make sure the windows and doors are cracked open. “Even just a few inches can make a big difference to improve ventilation,” Dr. Marr said.
More Ways to Protect Yourself and Others
If you gather with others, the C.D.C. says there are general precautions you can take to stay as safe as possible. Try to avoid shouting, cheering loudly or singing, which can increase the amount of respiratory droplets in the air. Instead, clap, stomp your feet or use noisemakers.
The C.D.C. also recommends bringing your own food, drinks, plates, cups and utensils.
If people drink too much alcohol, they might let their guard down or relax the rules. So be mindful of how the people around you are behaving and control how much you’re consuming so that you can keep a clear head.
Finally, don’t get lulled into a false sense of security. Even if everyone has been fully vaccinated, it can take a week or two after the second shot to build peak protection. And while vaccinated people are less likely to get severe Covid-19, experts don’t yet know if they can still spread the virus to others, said Dr. Asaf Bitton, a primary care physician at Brigham and Women’s Hospital who specializes in public health.
Finally, remember that negative Covid tests are no guarantee of safety. The virus may not have been detectable on the day of the test or the result could be a false negative.
“One test at one point in time is just not going to give you the clarity that you need to know that it’s safe for your groups to get together,” Dr. Bitton said.
