An Air France flight en route to Detroit Metropolitan Airport was diverted to Montreal, Canada, on Friday after officials discovered a passenger on board who had traveled from a region affected by Ebola.

U.S. Customs and Border Protection (CBP) officials alerted Canadian authorities that the passenger had boarded the aircraft "in error," according to a CBP spokesperson. The flight, Air France Flight 571, had departed from Paris Charles de Gaulle Airport.

Upon landing in Montreal, the passenger was met by health officials. Details regarding the passenger's specific travel history or current health status were not immediately released. The diversion occurred out of an abundance of caution, given the ongoing concerns surrounding the Ebola virus.

Authorities have stated that the passenger's presence on the flight was due to a procedural oversight. The incident highlights the sensitive nature of international travel protocols when dealing with potential public health risks, especially concerning infectious diseases like Ebola.

This situation underscores the heightened vigilance at international borders and airports in managing the risks associated with travelers arriving from areas known to be experiencing outbreaks of serious diseases. Health screening and passenger manifest checks are critical components of these protocols.

Air France has not yet released a statement regarding the incident. The flight was expected to continue its journey to Detroit after the situation was resolved, though the exact timeline for its arrival was not provided.

Officials are investigating how the passenger was allowed to board the flight despite the travel restrictions or screening measures that should have been in place. The incident is likely to prompt a review of screening procedures for flights arriving in the United States from affected regions.

Further information is expected to be released as the investigation progresses and health assessments are completed.
