On Monday, the Centers for Disease Control and Prevention updated its holiday guidance, noting the virus crisis is worsening and that small household gatherings are “an important contributor.” The CDC said older adults and others at heightened risk of severe illness should avoid gathering with people outside their households.

Experts point to Canada, where Thanksgiving was celebrated Oct. 12. Clusters of cases tied to family gatherings followed. “This sucks. It really, really does,” Canada Prime Minister Justin Trudeau said two weeks later.

There’s no need to cancel the holiday. Spending time with loved ones is important for health too, said Lacy Fehrenbach, Washington state deputy secretary of health.

The coronavirus spreads more easily when people are crowded together inside, so Fehrenbach encourages new outdoor traditions such as hiking as a family.
