A US Airways Express flight from Texas to Arizona ended up being more dramatic than passengers had expected when they boarded.

First responders boarded the plane upon landing in Phoenix and removed a man who was told to put on a medical mask. A spokesman for US Airways said the airline was notified after the plane left Austin the passenger’s status had been changed to “no-fly” because of medical conditions.

Passengers told Fox News they were told to get tuberculosis tests and vaccinations by a first responder who boarded the plane while it was on the tarmac. Federal and Maricopa County health officials said they had no immediate confirmation the passenger had an infectious disease.

However, a spokeswoman for the Maricopa County Department of Public Health told ABC15 passengers “faced little risk of contagion.”

Tuberculosis can be spread through the air.
