Sixteen Nigerians with underlying medical conditions have died this year while transiting through Ethiopia, prompting Nigerian authorities to issue an urgent travel warning. Officials cautioned that passengers using Addis Ababa airport face hidden hazards linked directly to its elevation above sea level.
For millions of international travellers moving across continents, the warning puts a spotlight on a stopover many consider routine. The Nigerian foreign ministry warned that citizens dealing with cardiovascular conditions or severe respiratory issues face heightened dangers when stepping off a plane into the city’s thin mountain air.

Bole International Airport operates as one of the busiest transfer hubs on the continent, handling heavy traffic between Africa, the Middle East and Asia. If you have an existing heart or lung condition and plan to fly through the facility, Nigerian officials suggest you may need to rethink your travel arrangements or seek immediate medical clearance before boarding.
The altitude threat at Addis Ababa airport
Addis Ababa sits at an altitude of 2,334 metres (7,657 feet), ranking it among the highest capital cities on earth. At that elevation, the atmospheric pressure drops and oxygen molecules spread out, meaning each breath delivers significantly less oxygen to the bloodstream than at sea level.
The Nigerian foreign ministry confirmed the 16 fatalities occurred among transiting passengers who had pre-existing illnesses. Officials did not publicly release the names of the victims or the formal medical causes of death, but they pointed directly to the physical strain caused by the change in elevation.
While Bole International Airport serves as a vital crossroad for global routes, the geographic setting of the Ethiopian capital creates an unforgiving environment for compromised bodies. Travellers often arrive after long flights already fatigued, which compounds the physiological stress of the mountain air.
Why thin air harms vulnerable passengers
High altitude travel risks stem from the rapid drop in available oxygen, which forces the cardiovascular system to adapt instantly. When less oxygen reaches the blood, the heart must beat faster and pump harder to supply vital organs.
According to the American Heart Association, that extra workload can trigger sudden complications, including heart failure, in patients whose cardiovascular systems are already damaged. Even otherwise healthy travellers can experience altitude-related symptoms such as dizziness, headache, fatigue and shortness of breath.
For people already managing chronic lung disease or narrowed arteries, those symptoms can escalate quickly into life-threatening emergencies. The sudden shift from a pressurised cabin to the thin air of the Ethiopian plateau can overwhelm a weakened respiratory tract before a passenger even clears their gate.
What the advisory asks travellers to do
Nigerian authorities stated clearly that they are not imposing a travel ban or asking airlines to halt flights through the region. Instead, officials urged passengers to book a thorough check-up before departure.
The ministry advised anyone managing health conditions aggravated by high elevations to exercise caution and obtain clinical guidance prior to travelling through Addis Ababa. Booking alternative flight paths that bypass high-elevation stopovers remains an option for travellers with unstable medical histories.
Airlines and travel agents across West Africa are now expected to field questions from worried ticket holders looking into their routing options. Travellers booked on upcoming itineraries through Ethiopia should monitor airline rebooking policies and speak with their doctors ahead of departure this week.
