The Centers for Disease Control and Prevention says a passenger on a Northwest Airlines flight from Frankfurt to Detroit has been diagnosed with tuberculosis.

Northwest says the passenger was on Tuesday's Flight 51 to Detroit Metropolitan Airport in Romulus.

CDC spokeswoman Shelly Diaz tells The Associated Press the risk is low that other passengers might contract tuberculosis. She said Sunday that health officials were seeking to contact 17 passengers seated near the sick passenger so they can be tested for tuberculosis as a "cautionary move."

Diaz says details about the sick passenger weren't being released. WDIV-TV reported the tuberculosis case Sunday morning.

Northwest Airlines was acquired last year by Atlanta-based Delta Air Lines Inc.
