This juror is sequestered — but not for deliberations.

A prospective juror who was dismissed from a Manhattan federal trial earlier this week has been told to self-isolate after attending temple the same day as someone who has been diagnosed with coronavirus, it was revealed in court.

The unidentified prospective juror — who has not been in the courtroom for days — received a letter from a health department and was told to self-isolate because of possible exposure to the person infected with the virus. It was unclear whether it was the state health department or a local body.

The court received notice of the prospective juror and moved the trial for Al Sadr Hashemi Nejad, an Iranian banker accused of violating US sanctions against the country, to another courtroom as a precaution.

Judge Alison Nathan said in court the prospective juror did not have symptoms of the virus.

“I think it went fine with the jurors, they seemed accepting of the information,” she said.

The person diagnosed with coronavirus was not identified.

Attendees of a Westchester County synagogue frequented by the state’s second confirmed case, Lawrence Garbuz, have been asked to self-isolate.

Those “who attended services on February 22, and a funeral and a bat mitzvah at the temple on February 23 must self-quarantine until at the very earliest March 8. Those who do not self-quarantine will be mandated to by the County Department of Health to do so,” Westchester County Executive George Latimer said in a press release about Temple Young Israel of New Rochelle.
