Masks cut COVID-19 incidence by 53%, new analysis finds
Mask-wearing cuts COVID-19 incidence by 53%, according to a new analysis that pooled results from multiple studies.
The analysis, published Thursday in the medical journal The BMJ, found that mask-wearing, social distancing and hand-washing were all effective in reducing the spread of COVID-19.
The bulk of the studies included in the analysis were conducted before mass vaccinations. The researchers, who were from several universities in Australia, Scotland and China, said that more studies are needed to understand the effectiveness of these public health measures in the context of widespread vaccination coverage.

Florida governor signs legislation prohibiting private employer vaccine mandates
Florida Gov. Ron DeSantis on Thursday signed legislation that prohibits private employer vaccine mandates and says employers that violate the ruling will be fined.
The legislation also states educational institutions can't require students to be vaccinated; school districts can't have face mask policies or quarantine healthy students; and families can "sue violating school districts."
"Nobody should lose their job due to heavy-handed COVID mandates," DeSantis, a Republican, said in a statement.
New York governor calls on workers to go back to the office
New York Gov. Kathy Hochul is calling on workers to head back to the office in the new year.
"How about this New Year's resolution: that in the days after New Year’s, that we say everybody back in the office. You can have a flex time, but we need you back, at least the majority of the week," Hochul told industry leaders at the Association for a Better New York breakfast.
Hochul also said she would be in Times Square on New Year's Eve.
Times Square is reopening this New Year's Eve after being closed last year due to the pandemic. Revelers must bring proof of full vaccination and a photo ID.
"I can't wait to put 2020 - 2021 behind us," the governor said.

Consider rapid testing before Thanksgiving, experts say
Former Baltimore health commissioner Dr. Leana Wen said in an interview Monday hosted by the Bipartisan Policy Center that her family is rapid-testing on Thanksgiving because they're gathering indoors with multiple families and have young, unvaccinated children.
She said it was reasonable for families with immunocompromised members to continue to take precautions, like rapid test and gather outdoors.
"A family in which everybody is generally healthy and fully vaccinated might take very different types of risks than a family with unvaccinated young kids or elderly, immunocompromised family members," she said.
Dr. Jerome Adams, former Surgeon General under President Donald Trump, said to make sure all relatives are vaccinated and that no one has cold symptoms.
"Even if you're vaccinated, if you're coughing, if you're sneezing, if you've got symptoms, you still could be spreading the virus," he said.
Looking to the future, Dr. Anthony Fauci said, "If we can get most of the people who are eligible to be boosted, boostered, we can go a long way to make in 2022 much more of a normal year than what we've seen in 2021."
