A Manhattan man in his 50s is the latest person to test positive for coronavirus in New York City, bumping the total number of cases in the Big Apple up to five, Mayor Bill de Blasio said Friday.

The latest case is associated with Lawrence Garbuz, 50, the Midtown lawyer hospitalized in stable condition at New York-Presbyterian/Columbia Medical Center.

“He has mild symptoms,” de Blasio said on WNYC Friday.

“We’re testing his family and the disease detectives are following up on his contacts,” de Blasio said.

He added that he’s “worried” about the condition of the Brooklyn woman in her 80s who tested positive for the disease late Wednesday.

Garbuz is continuing to improve, the mayor said.

Unlike one county in Washington state where officials recommended all residents work from home, de Blasio said New York City is not in that position because cases here are still largely isolated.

“I don’t think it’s the moment to take that kind of action. It could be changed tomorrow. It could be changed next week,” the mayor said.

The mayor responded to reports that public schools don’t have necessarily have cleaning supplies to protect against the COVID-19.

“Call 311 and report any school facility that doesn’t have soap and towels and we will rain holy hell on that school,” Hizzoner said.

De Blasio is expected to provide more updates on the outbreak later in the day.
