Mayor Bill de Blasio insisted Tuesday that there would be no Italy-style lockdown in the Big Apple to contain the coronavirus, even as he announced five new cases to bring the total to 25.

“We cannot shut down because of undue fear,” de Blasio said on MSNBC’s “Morning Joe.”

“I would advise against these mass closures when we’re keeping this situation relatively contained,” the mayor added.

He’s still not considering closing schools.

“I want to protect our kids more than anything, but this is a disease from everything we’re seeing that really doesn’t present a problem for our kids,” de Blasio said.

He called on the federal government to help the city get automated tests as well as more surgical masks and hand sanitizer.

“The federal government is still way too absent, there’s no firm hand on the wheel,” he said.

De Blasio also used the TV appearance to stump for Vermont Sen. Bernie Sanders and Medicare-for-all ahead of Tuesday’s crucial primaries in Michigan and other states.

“By the way, in the middle of the coronavirus crisis, this is the biggest advertisement — I wish it wasn’t, Joe — the biggest advertisement for why we need universal health care that we’ve seen in our lifetime,” he told host Joe Scarborough.

“If we had universal health care, a hell of a lot more people would have been tested, a hell of a lot more people could have been saved,” de Blasio said.
