Dr. James Pruden, who is in charge of emergency preparedness at the hospital, was one of the first medical workers who tested positive for the virus in the state.
The 70-year-old physician has been off ventilators for "a few days," and is breathing on his own, said Murphy at his daily news briefing.
Pruden, who lives in Teaneck -- the epicenter of Bergen County's coronavirus outbreak -- has worked as a physician at the medical center for nearly four decades.
He was tested positive a short time after he completed the COVID-19 emergency preparation protocols for St. Joseph’s, reports say.
Pruden was admitted to the ICU in isolation on March 6 after experiencing upper respiratory problems and “cold-like symptoms,” reports say.
New Jersey had 8,825 cases of coronavirus including 108 fatalities as of Friday.
