About 70 passengers on a US Airways Express flight from Texas to Arizona were briefly kept on the plane after it landed, and some say they were told to get tuberculosis tests and vaccinations.
Responders on Saturday boarded the plane in Phoenix and removed a man who was asked to put on a medical mask.
US Airways spokesman Bill McGlahsen says the airline was notified after the plane departed Austin that the passenger’s status had been changed to “no-fly” because of an unspecified medical condition.
Federal and Maricopa County health officials said there was no immediate confirmation that the passenger has an infectious disease.
Tuberculosis is a respiratory disease that can be fatal. The Centers for Disease Control says it is spread through the air.
