Nearly 6,100 people a day are now testing positive for COVID-19 in New York — up 22% from roughly 5,000 for the seven days through Nov. 11.
That's the highest seven-day average since mid-April.
Meanwhile, the latest federal data show more then two-thirds of New Yorkers are fully vaccinated.
"There is one simple solution to ensure New Yorkers can enjoy a safe holiday season - get vaccinated if you haven’t already and get a booster shot if you have," Gov. Kathy Hochul said in a Saturday statement.
The vast majority of the state's 62 counties are seeing sharp upticks in new COVID-19 positives: from a 32% increase in cases over the seven days through Thursday on Long Island, to a 37% increase in Niagara County in western New York.
And hospitals in New York reported 2,249 confirmed COVID-19 patients as of Friday, up 20% from the previous Friday.
Hospitalization rates are flat in some communities including Manhattan and Albany.
But much of the state, from Saratoga to Erie County, is also seeing sharp increases in hospitalizations. Saratoga, for example, is up to 35 patients with confirmed COVID-19, nearly triple from 12 patients as of Friday Nov. 12.
In Central New York, Onondaga County is up to 128 patients — a 33% increase.
Monroe County, in the Finger Lakes, is up to 244 patients, up 30%.
And hospitals in Erie County reports 227 patients, a 23% increase.
Hochul earlier this week warned that a continued uptick in COVID-19 rates could mean New Yorkers will again face more virus protocols in high-risk communities.
But the governor hasn't laid out any specific protocols that she could reinstitute, and she hasn't offered a threshold for how high rates could rise before she'll act.
Attorney General Letitia James, a Democrat who's running for governor, released a statement Saturday calling on Hochul to address the spike.
She pointed out that large swaths of the state — including much of central, western and Northern New York — are seeing higher hospitalization levels than at this point in 2020.
"It is time to act now to save lives," James stated. "Anything short of bold action is unacceptable."
