The first staffer in the city’s Department of Correction has tested positive for coronavirus — and another employee has been ordered to self-quarantine, The Post has learned.

The infected worker “has not been at work for several days and won’t be back until cleared to return to duty by… the department’s Health Management Division,” reads a memo from Commissioner Cynthia Brann and Chief of Department Hazel Jennings, which was obtained by The Post on Sunday.

The person is a civilian employee in the agency, not a corrections officer, sources confirmed. It was unclear where the staffer worked or what the person’s condition was Sunday.

A spokeswoman for the DOC confirmed that an employee tested positive for COVID-19 and “is now under the care of a medical professional.”

Another employee who worked “in close proximity” with the person who tested positive for the virus is under a 14-day quarantine, according to the spokeswoman

“We will continue to trace close contacts,” the spokeswoman said.

DOC officials reassured employees in the memo that anyone who had been in close contact with the infected person, who’s name was not released, would be contacted and “appropriate precautions” would be taken.

“This is not a time to panic, it is a time to recognize our systems works,” the memo reads.

The positive test comes two days after the corrections officers’ union called for a temporary stop on visitors to city jails.

“I don’t know what has to be done for city hall to be convinced that the visits have to be suspended for at least 30 days until we get a grip soon things,” Elias Husamudeen, president of the Correction Officers’ Benevolent Association, told The Post Sunday.

“A civilian can stay home, correction officers can stay home, but an inmate, they are going to be in this environment and it’s going to be who knows how long before we know he or she has contracted it.”
