UPDATE — Members of two families in New Rochelle have tested positive for the new coronavirus and have gone into quarantine, Gov. Andrew Cuomo said at a late afternoon press conference. The number of confirmed cases of COVID-19 increased to 11 in New York. The Westchester Torah Academy joined the list of closed schools.

WHITE PLAINS, NY — About 500 people are expected to go into either mandatory or self-quarantine in Westchester County and New York City after a family and neighbor in New Rochelle tested positive for the new coronavirus, Gov. Andrew Cuomo said in a news conference Wednesday after noon in White Plains. "They will be contacted; between county, state and private organizations, they'll be given information on what that means," he said.

The affected people include congregants and attendees at recent events at Young Israel of New Rochelle synagogue; eight staffers at New York Presbyterian-Lawrence Hospital in Bronxville; students and staff at the SAR Academy in Riverdale; some people at Yeshiva University; and members of the hospitalized man's midtown Manhattan law firm. They're all on the list of people who may have come in contact with a New Rochelle family with coronavirus: the 50-year-old father, who is hospitalized, his wife, a 14-year-old daughter and a 20-year-old son; and the neighbor who drove the father to Lawrence Hospital.

The neighbor's children are also being tested, Cuomo said.

The 50-year-old New Rochelle man who was confirmed to have the virus is stable and improving at a New York City hospital, Cuomo said. County and state health department officials are investigating more possible points of contact now, Cuomo said.

There are two types of quarantine, Cuomo said: mandatory isolation for those who have tested positive, and self-quarantine for those who are at risk because of potential contact with contagious people. Anyone who has tested positive must isolate themselves from others even in their home.



"If you can't, then we will find you a place you can be quarantined," Cuomo said. "That is a mandatory quarantine. We check on those people to make sure they are doing it. That's being policed by the local health departments with regulation from the state."

The county has set up a hotline specifically for people who are being quarantined because of the New Rochelle case, Westchester County Executive George Latimer said. Other Westchester residents should call 211 if they have questions about the virus and exposure. Latimer said the immediate focus is on tracking the movements of the people who tested positive — "detective work we have to do at the county level."
