Part of the Port Authority bus terminal was briefly closed Thursday evening as authorities investigated a man's claims that he "may have Ebola," officials say.

The lower level of the North Wing, comprising gates 60 to 85, was closed during the evening rush. Police were seen stationed outside the cordoned-off gates.

They were reopened by 6 p.m.

Law enforcement sources said the investigation was sparked by a sick man who arrived on a bus from Detroit and announced he may have Ebola.

The man was taken to Bellevue Hospital for an examination, the FDNY confirmed.

Doctors there say there's no indication the man has any communicable diseases, according to Port Authority spokesman Neal Buccino.

The gates were closed "out of an abudance of caution for cleaning," Buccino said.

The North Wing houses the Greyhound and Trailways bus ports and ticketing.

Despite widespread concern over the deadly virus in 2014 -- and several scares -- only one man was ever diagnosed with Ebola in New York City; Dr. Craig Spencer, who treated Ebola patients in Guinea with Doctors Without Borders, recovered successfully.
