NYC urges masks indoors "at all times" regardless of vaccination status

• The advisory recommends city residents wear a mask "at all times when indoors and in a public setting," but stops short of reinstituting a mask requirement.
• Mayor Bill de Blasio also said that while there are currently no reported cases of the variant in New York City, "it is very likely there will be."

What they're saying: We "still have a lot to learn about the Omicron variant, but its emergence lends urgency to the importance of the precautions we've all become familiar with," Chokshi said in a press conference.

• "Cases have been rising, including among our youngest New Yorkers in recent weeks," he added.
• "Our understanding of Omicron will advance and we'll be able to adjust our public health strategies accordingly."
