Coronavirus cases in New York state rose to 105 on Sunday, 16 more than the day before, Gov. Andrew Cuomo said.

NEW YORK (AP) - The number of coronavirus cases in New York state rose to 105 on Sunday, 16 more than the day before, Gov. Andrew Cuomo said.

The largest concentration of cases, 82, is in suburban Westchester County north of New York City. There are 12 cases in New York City, 2 upstate in Saratoga County, and a handful of others on Long Island and in Rockland and Ulster counties.

Cuomo called on the federal Centers for Disease Control and Prevention to allow private laboratories to do testing to greatly expand the number of tests that can be done.

“The more positives you identify, the more you can isolate people and stop the spread,” Cuomo said.

The Westchester outbreak has been traced to a synagogue in New Rochelle where the congregation was asked to self-quarantine after a 50-year-old man in the community was hospitalized with the illness. A growing number of friends and relatives of the patient have tested positive.

Cuomo said nursing homes near the Young Israel of New Rochelle synagogue will suspend outside visitors as a precaution. Several schools in Westchester and neighboring Rockland County were closed over the weekend for deep cleaning.

Cuomo declared a state of emergency on Saturday to clear the way for more testing, purchases of more supplies and hiring of workers to help monitor self-quarantined patients. Cuomo said expanded testing by qualified professionals could detect additional cases faster so they can be put in isolation to limit the disease’s spread.

PREVIOUS REPORT

ALBANY - Gov. Andrew Cuomo declared a state of emergency in New York on Saturday as the number of coronavirus cases in New York swelled, doubling from a day early.

On Saturday night, Cuomo said the total number of confirmed cases jumped to 89, up from 44 on Friday and fueled by a surge in cases tied to a community in New Rochelle in Westchester County.

After putting the state total at 76 cases midday, Cuomo said another 13 people tested positive later Saturday - all from Westchester.

That put the Westchester total at 70, or nearly 79% of the total statewide.

"We are working to do more testing as quickly as possible to find the people who are infected and help contain the spread of the virus," Cuomo said in a statement.

"There are going to be more cases because we are testing more people - that's a good thing because then we can deal with the situation based on more facts."

He said the state is looking to expand the closing of schools in New Rochelle.

"Westchester is an obvious problem for us," Cuomo said in an earlier briefing Saturday.

He said 10 of the 76 people are hospitalized, pointing out that 80% of people will get better on their own.

Cuomo announced New York now has its first cases outside the New York metropolitan area: Two cases were confirmed in Saratoga County.

The governor said the precautionary quarantines in Westchester, which have jumped to 1,000 people, would likely continue as the virus spreads and more people have become infected.

He announced he issued an emergency declaration that would help in the response to coronavirus by state and local governments, allowing him to expedite purchasing goods and hiring people.

"This is labor intensive," Cuomo said.

Cuomo said the cases in Westchester all appear to link back to the first man who tested positive Tuesday — a member of the Young Israel synagogue in New Rochelle.

The temple announced Saturday that it would remain closed through March 14, and those who were there Feb. 29 will remain on a voluntary self-quarantine through that date.

One of the cases is the rabbi at the temple, and it said his wife, too, has since tested positive.

Outside visitors to nursing homes and senior living facilities in the New Rochelle area will also be banned, Cuomo said, saying the elderly remain the most vulnerable population.

"The nursing home are the most problematic settings for us with this disease,” he said.

In Monroe County, a local patient was placed in isolation at Rochester General Wednesday, after displaying symptoms consistent with COVID-19. Results, however, came back negative after samples were sent to the state public health laboratory in Albany for analysis.
