Traditional trick-or-treating involves close, face-to-face contact with people outside your household. Avoid it, says Dr. Desai.
“You’re going up to a new household. They open their door. You’re within 6 feet of each other,” says Dr. Desai. “Even though the interaction is brief, it’s still an exposure.” (For the same reasons, Dr. Desai discourages apartment building trick-or-treating, which has the added factors of being indoors and potentially crowded hallways and elevators.)
If you want to trick-or-treat, look for ways to participate in one-way trick-or-treating. People have come up with creative solutions, such as a homemade candy chute or leaving individually wrapped goody bags at the end of their driveway. (The CDC considers this a moderate-risk activity.)
The key is to minimize contact wherever possible. “If you pass by a house where there’s a big bowl of candy for everyone to pick out of, skip that house and move on to houses where they’ve left out individually wrapped candy bags,” advises Dr. Desai. “That way you don’t have to worry as much about who else has touched it before.”
