A New Jersey hospital’s director of emergency preparedness is in critical condition after testing positive for the coronavirus, officials said Monday.

Dr. James Pruden, 70, remains isolated at St. Joseph’s University Medical Center in Paterson after he began experiencing symptoms of the deadly virus March 1, according to hospital officials.

“Dr. Pruden remains critical but stable,” hospital spokeswoman Pamela Garretson told The Post.

Pruden, who lives in Teaneck, was admitted March 6 with upper respiratory problems and cold-like symptoms, NorthJersey.com reported.

St. Joseph’s Health President Kevin Slavin later confirmed Pruden’s COVID-10 diagnosis Thursday at a press conference, saying the doctor gave him permission to release his identity.

“He recognizes by sharing his name and condition it may encourage others to come forward and get tested,” Slavin said. “The point we want to make is we are all at risk of this.”

Slavin added that hospital staff and patients who had come into contact with Pruden were tested for coronavirus and none of their results have come back negative.

Anyone who believes they were in contact with Pruden between March 1 and March 6 is urged to contact health officials.

A call to Pruden’s home went unanswered Monday.

The American College of Emergency Physicians confirmed that two emergency doctors, including one in Paterson, were in critical condition after contracting the virus, CNN reported.

“I am deeply saddened by this news, but not surprised,” President William Jaquis said in a statement. “As emergency physicians, we know the risks of our calling. We stand united with our colleagues and our thoughts and prayers for a full and speedy recovery are with each of them and their families.”
