Halloween Covid guidance - University mental health - Global methane pledge

White House chief medical adviser Dr. Anthony Fauci told CNN Sunday that kids can "go out there and enjoy Halloween," an approach he attributed to the fact that more and more people are now vaccinated against Covid-19 and that most Halloween activities, including trick-or-treating, are held outdoors.

“It’s a very important part of the year for children," [Fauci said]. Fauci's go-ahead on Halloween comes as Covid-19 hospitalizations, cases and deaths are declining nationwide. But experts caution the virus could rebound if enough people remain unvaccinated.

In most cases, [children should not have to mask while trick-or-treating] according to Dr. John Brownstein, an epidemiologist and chief innovation officer at Boston Children's Hospital. "Every parent has to make their own sort of risk calculation, but given where we are in this pandemic, I think, generally, mask-wearing outside is probably unnecessary," said Brownstein.
