Wearing a mask on New York City mass transit is now optional.

New York Gov. Kathy Hochul announced Wednesday that the decision was based on the latest COVID-19 numbers, which she highlighted were on a "phenomenal trend," as well as Centers for Disease Control and Prevention guidance. The seven-day average of cases totaled 3,400 and there were 17.8 cases were 100,000 people, with hospitalizations also "stabilized."

Hochul presented a yellow sign that would be posted, reading: "Masks are encouraged but optional. Let's respect each other's choices." 

"What that means is, you choose not to have a mask. That is your personal decision. You'll do your own personal risk assessment of who you're exposed to, your own vulnerabilities, where you work … You make your own determination, but do not judge your fellow passengers on what their choices are. Let's be respectful," she said.

While variants are still at-large, masking requirements will remain in effect in state-regulated health care facilities and clinical settings.

Hochul got a COVID booster shot live during the press briefing.

"And also, people are getting back to work and they're getting back to school," she replied, noting that if people aren't wearing a mask in those places "it makes sense to not worry about it on the way."
