To avoid Covid, here are four questions to ask family and friends ahead of Thanksgiving gatherings

Thursday marks the second Thanksgiving during the coronavirus pandemic. Many grandparents are excitedly planning to see their grandchildren. Friends are dressing their dining tables for turkey and loved ones. Some people have flights booked or road trips scheduled.

But in the background, Covid-19 case numbers are inching upward across the United States and millions of Americans remain unvaccinated -- leaving some people worried about the possible Covid-19 risks that could come with their Thanksgiving plans.

If you have concerns, experts say there are some important questions to ask to help weigh your risk: Will those around you be vaccinated? Have they been tested? Should you open windows when indoors?

Results from a new Axios/Ipsos survey, released Tuesday, found that among 682 US adults who are planning to see people for Thanksgiving this year, 31% said that they view there to be a "large or moderate risk" in seeing friends or family for the holiday -- down from 64% a year ago.
