A private Jewish high school in Bergen County will be closed for several days after dozens of its students were potentially exposed to the coronavirus at a bat mitzvah in New York last month.

The Frisch School on West Century Road in Paramus will be closed until at least Wednesday “out of an abundance of caution,” Principal Eli Ciner told NJ Advance Media on Friday.

The students traveled in late February to a bat mitzvah at Young Israel of New Rochelle, where some students began a self-quarantine period earlier this week.

At least one student in New Rochelle has developed symptoms and is being tested for the virus, Ciner wrote in a letter to parents on Thursday, according to the Jewish Telegraphic Agency.

Officials advised state residents who were present at the Westchester County to self-quarantine out of concern they might have been exposed to the coronavirus late last month, state Health Commissioner Judith Persichilli said Wednesday.

The state advised anyone who visited Temple Young Israel in New Rochelle, New York, for services, a funeral or a bat mitzvah from Feb. 22-23 to remain at home until at least Sunday.

“While the risk to any given individual is likely to be low, we felt it was important to share this guidance for any New Jersey residents who may have attended these services and events,” Persichilli said.

“The (Frisch) school is closed and will remain closed next week,” Ciner said Friday. He declined to say whether any of the Frisch students had displayed symptoms of COVID-19.

In Bergen County, two people have tested positive for coronavirus in initial tests by the state – a 32-year-old man from Fort Lee and a woman in her 30s from Englewood, state officials have said. Those tests are pending confirmation by the Centers for Disease Control.

The Fort Lee man was hospitalized at Hackensack University Medical Center while the woman was sent home from Englewood Hospital and Medical Center to self-isolate, officials said.

Persichilli said any positive case of novel coronavirus is "concerning,” but added “most New Jersey residents are at very low risk of contracting” the virus.

At least nine people tested negative for the coronavirus in New Jersey in recent weeks. But officials warned that the virus was likely to spread.

There are more than 93,000 cases worldwide and more than 3,100 deaths from COVID-19, mostly in China. The virus has infected more than 99 people in the U.S. and killed 10, according to the CDC.

In a memo to school superintendents, the state advised all public schools to plan for building closures in what could be a potential coronavirus outbreak. State officials said home instruction would count toward the required 180-day school year if districts are ordered to close.
