An Air France flight traveling from Paris to Detroit was diverted to Montreal Wednesday following U.S. travel restrictions tied to the Ebola outbreak across multiple African nations. The incident involved a passenger originating from the Democratic Republic of Congo (DRC).

U.S. Customs and Border Protection stated the airline mistakenly boarded the individual on a flight destined for the United States. CBP confirmed the passenger “should not have boarded” the plane due to entry restrictions designed to mitigate Ebola virus transmission risks, though it did not specify when the person last entered the DRC. Air France reported the diversion occurred “at the request of U.S. authorities” and emphasized there was “no medical emergency on board.”

The Centers for Disease Control and Prevention (CDC) implemented a 30-day entry ban Monday for travelers who have been in DRC, Uganda, or South Sudan within the past 21 days. The order, based on recent outbreak data, aims to address the risk of Ebola introduction into the United States while allowing time for public health assessments and response planning.

The Bundibugyo virus strain currently causing concern is not covered by vaccines or antibodies developed for the more common Ebola variant. CDC data indicates this strain has a fatality rate ranging from 25% to 50%, with treatment limited to supportive care.

World Health Organization Director-General Tedros Adhanom Ghebreyesus noted Wednesday that while the risk of regional spread in Congo and Uganda remains high, global transmission is currently low despite over 130 deaths reported. He stated there are nearly 600 suspected cases and 139 confirmed fatalities.
