The Manhattan lawyer hospitalized with coronavirus commuted regularly from his home in New Rochelle on the Metro-North Railroad, according to a report Tuesday.

But it’s unlikely that he used the city’s subway system because his office is within walking distance of Grand Central Terminal, ABC News said, citing a source familiar with the case.

During a news conference Tuesday, MTA Chairman Pat Foye said transit officials “don’t know whether that patient traveled to New York City using public transportation or not.”

Gov. Andrew Cuomo’s office said the man’s movements were “still being looked at.”

But Mayor Bill de Blasio wouldn’t discuss the matter during a City Hall news conference.

“The subway is not the issue, the train is not the issue. The issue is prolonged, consistent contact,” he said.

Coronavirus is believed to spread mainly through “respiratory droplets produced when an infected person coughs or sneezes within about six feet of another person,” according to the federal Centers for Disease Control and Prevention.

“These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs,” according to the CDC website.

“It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.”
