An Air France Boeing 777-200 flying from Paris Charles de Gaulle to Detroit Metropolitan Airport was diverted to Montreal Trudeau International Airport after U.S. authorities blocked entry due to a deadly Ebola outbreak in Central and East Africa, sparking a global aviation disruption. The diversion reflects the immediate impact of new U.S. travel restrictions, implemented to contain the Bundibugyo Ebola strain, which has already caused fatalities in the Democratic Republic of the Congo, Uganda, and South Sudan. Airlines and passengers are facing sudden operational interruptions, as enhanced screening and entry bans target travelers recently present in affected regions, underscoring the urgent public health response to a rapidly escalating outbreak.

Flight AF-378, operating under a Delta Air Lines codeshare, was carrying up to 312 passengers when it was rerouted, landing safely in Montreal at approximately 5:30 pm local time. The mid-flight announcement of the diversion highlights the operational challenges airlines face amid evolving international health directives, as authorities continue to enforce strict measures to prevent the spread of Ebola across North America and Europe.

New U.S. Travel Restrictions

On May 18, 2026, the Centers for Disease Control and Prevention (CDC), in coordination with the Department of Homeland Security (DHS) and other federal agencies, issued a public health order introducing enhanced travel screening and entry restrictions. The measures are designed to prevent the Bundibugyo strain of Ebola virus, currently circulating in parts of East and Central Africa, from entering the United States. The order is set to remain in effect for 30 days.

Under the restrictions, non-U.S. citizens who have visited Uganda, the Democratic Republic of the Congo (DRC), or South Sudan within the last 21 days are prohibited from entering the United States. U.S. citizens, lawful permanent residents, and service members are exempt from these restrictions. All travelers are subject to enhanced screening upon arrival at U.S. ports of entry.

Ebola Outbreak in East and Central Africa

The restrictions come in response to a rapidly escalating outbreak of the Bundibugyo Ebola virus strain, which has already resulted in more than 80 deaths in the DRC and additional fatalities in Uganda. The outbreak is concentrated in Ituri Province in eastern DRC, where conflict, fragile healthcare infrastructure, and porous borders have hindered containment efforts.

According to the World Health Organization (WHO), the Bundibugyo strain is highly virulent, with fatality rates historically ranging between 30% and 50%. Currently, there are no licensed vaccines or targeted therapeutics available to treat this variant, increasing the urgency of preventive measures such as travel restrictions and enhanced screening protocols.

Implications for International Travel

While Air France does not operate direct flights to the affected countries, it maintains connections to regional hubs such as Kinshasa in the Republic of Congo, which shares a border with the DRC. The diversion of AF-378 illustrates the broader operational challenges airlines face when navigating rapidly changing international public health directives.

The U.S. State Department has issued Level 4 travel advisories for the DRC, Uganda, and South Sudan, strongly discouraging travel for American citizens and permanent residents. These advisories emphasize the risks associated with exposure to Ebola and the potential for rapidly evolving local conditions.

International health authorities, including Africa CDC, recognize the United States’ responsibility to protect public health but have urged governments worldwide to avoid unnecessary travel or trade restrictions that may exacerbate economic and logistical disruptions in affected regions.

Airline and Airport Operations

The sudden diversion required coordination between multiple parties, including Air France, Delta Air Lines, Montreal Trudeau International Airport, U.S. Customs and Border Protection, and the CDC. The incident underscores the complexity of international airline operations under emergent public health crises, where even flights not directly originating from affected regions may be subject to restrictions based on passengers’ travel histories.

Airlines continue to adjust operational protocols, including enhanced passenger health screening, updated flight routing, and staff training on infectious disease response. These measures aim to protect travelers, airport personnel, and broader communities while ensuring continuity of air transport services.

Public Health and Preparedness

Experts note that early and decisive travel interventions are critical for limiting the spread of Ebola, particularly in countries with limited healthcare infrastructure and ongoing humanitarian challenges. The outbreak has highlighted the importance of cross-border collaboration, rapid information sharing, and robust screening protocols to safeguard global health.

The CDC’s public health order, alongside international travel advisories, reflects the United States’ commitment to preventing Ebola introduction while balancing the economic and logistical challenges posed to airlines, travelers, and airports.

Looking Ahead

As the Ebola outbreak continues to evolve, airlines and travelers must remain aware of updated travel guidance and restrictions. Authorities recommend monitoring official CDC updates and following international advisories to reduce the risk of exposure. Health agencies worldwide continue to coordinate containment strategies, including enhanced surveillance, public awareness campaigns, and support for local healthcare facilities.

This incident serves as a reminder of the global implications of regional health crises and the need for vigilant monitoring, coordinated response, and clear communication between health authorities, governments, and the aviation industry.

Air France Boeing 777 flying from Paris to Detroit was diverted to Montreal after U.S. authorities enforced travel bans amid the deadly Ebola outbreak, triggering a global aviation emergency. Enhanced screening and entry restrictions for travelers from Central and East Africa disrupted international flight operations and airline schedules.

The diversion of Air France flight AF-378 to Montreal underscores the far-reaching impact of the Ebola outbreak on global aviation and international travel. As U.S. travel restrictions and enhanced screening measures continue, airlines and passengers must navigate sudden operational disruptions while prioritizing public health safety. The situation highlights the critical importance of coordinated international response, vigilant monitoring, and preventive measures to contain the spread of Ebola, ensuring that global air travel remains safe, secure, and responsive to emerging health threats. Travelers are advised to stay updated on official travel advisories and airline announcements as authorities continue to enforce precautionary measures.
