Do their part in the battle against covid-19 -- in statements on wednesday -- various professors warned that trick-or treating is not safe this year and kids should be kept home.
Others say do your best to make it as safe as possible.
Erin bromage, university of massachusetts- dartmouth, biology professor/"when the children knock on the door, it becomes a really tight, confined space with number of people there yelling 'trick or treat.'
And that just creates that close environment that we really are trying to avoid right now."
While the c-d-c has already classified high contact trick or treating as high risk -- the agency says the tradition can be made safer by -- wearing a mask -- washing hands before touching treats -- avoiding direct contact with trick or treaters -- g treats outdoors -- or even setting up a station with individually bagged treats for kids to take.
Erin bromage, university of massachusetts- dartmouth, biology professor/"i'm really proud of what they're doing in my neighborhood everyone is setting up tables down the end of their driveway.
Some people have put out big spiderwebs and they're hanging the candy from the spiderwebs so the kids are still having the trick or treating experience this there's a social aspect to it, but it's done in a way that's safe."
