A baby boy is being tested for COVID-19 after dying in the Big Apple just days after being discharged from a hospital with a coronavirus-like infection, police sources told The Post.

The 1-year-old had been in NYU for two days last week for an upper respiratory infection, sources said.

He was discharged on Saturday and found unconscious by his dad at their Brooklyn home on East 23rd Street in Sheepshead Bay at around 8 a.m. Monday, the NYPD said.

He was taken to a Manhattan hospital but pronounced dead at 9:30 a.m., police said.

Because of his symptoms, his body was tested for COVID-19, and the tests later came back negative, another source familiar with the situation told The Post.

The Medical Examiner will determine the cause of death, police said.

The boy’s family was on Tuesday sitting shiva at their home, with a group of teary-eyed mourners sitting in a circle inside.

“There’s no story here — it’s nothing to with [coronavirus],” a man who answered the door insisted to The Post.

Health officials at the World Health Organization and elsewhere have previously claimed that children are not as severely impacted by COVID-19 and typically only display mild symptoms.
