Nigeria Warns Travellers After 16 Deaths in Addis Ababa

Nigeria’s government has issued a new travel advisory for journeys passing through Addis Ababa after its diplomatic mission in Ethiopia recorded 16 deaths involving Nigerian travellers this year, with publicly available information linking the fatalities to health complications associated with the city’s high altitude.

High-Altitude Conditions Put Transit Hub Under Scrutiny

The advisory, released in mid November 2026 by Nigeria’s Ministry of Foreign Affairs, focuses on the specific risks posed by Addis Ababa’s elevation. The Ethiopian capital sits at about 2,355 metres, or 7,726 feet, above sea level, where lower atmospheric pressure reduces the amount of oxygen available with each breath compared with airports at lower altitudes.

According to published coverage of the advisory, Nigerian officials reported that 16 citizens died this year while transiting through Addis Ababa, with the incidents linked to suspected altitude-related complications. The fatalities were recorded by Nigeria’s diplomatic mission in the city and involved passengers who were not staying in Ethiopia long term but using Addis Ababa as a regional air hub.

Reports indicate that the travel notice is framed as a health advisory rather than a blanket security warning. Addis Ababa remains one of Africa’s busiest aviation gateways, with large volumes of connecting traffic from West Africa to the Middle East, Asia and other parts of the continent. The Nigerian government’s intervention is therefore aimed at a specific category of at-risk travellers rather than all passengers.

Publicly available information on the advisory stresses that high-altitude environments can trigger or worsen symptoms for people with underlying conditions. While many passengers may experience only mild shortness of breath or fatigue, others can face far more serious complications if they are not medically prepared.

Warning Targets Travellers With Existing Health Conditions

The new guidance is directed in particular at Nigerians with pre-existing cardiovascular or respiratory illnesses, such as heart disease, hypertension, asthma and chronic obstructive pulmonary disease. Published coverage of the advisory notes that people undergoing active medical treatment or recovering from major surgery are also considered potentially vulnerable.

The Ministry of Foreign Affairs, through its public statement, urges such travellers to seek professional medical advice before booking routes that involve stopovers in Addis Ababa. Health practitioners can provide fitness-to-fly assessments, adjust medication schedules and recommend oxygen support or other precautions if necessary.

Information in the advisory explains that, although healthy individuals generally adjust to the thinner air without major problems, reduced oxygen levels can place extra strain on the heart and lungs. For passengers whose organs are already compromised, the combination of cabin pressurisation, altitude at destination, long-haul flight fatigue and possible dehydration can sharply increase health risks.

Reports further highlight that the government’s message is one of caution rather than panic. Travellers are being encouraged to make informed decisions, disclose relevant medical histories during pre-travel consultations and ensure that any required medication is carried in hand luggage for ready access during flights and layovers.

Transit Through Bole International Airport Under the Spotlight

Addis Ababa Bole International Airport serves as a major connecting point between West Africa and destinations in Europe, the Gulf, India, East Asia and southern Africa. Nigeria’s advisory has drawn attention to how quickly travellers can be exposed to high-altitude conditions during even short transit windows.

Publicly available information from earlier consular guidance shows that Nigerians transiting through Addis Ababa who wish to leave the airport for hotel accommodation generally require a valid Ethiopian entry visa. Passengers without such documentation are normally obliged to remain airside within the terminal for the duration of their layover, which can last many hours on some itineraries.

In practice, this means that vulnerable travellers may spend extended periods in a pressurised aircraft cabin followed by time at a high-altitude airport without the chance for proper rest or medical evaluation. The combination can be particularly challenging for older passengers or those travelling alone, which is one reason Nigeria’s diplomatic mission has been tracking medical incidents among its nationals.

While no changes have been announced to airline schedules or ticketing rules, the advisory is expected to prompt some Nigerian travellers and travel agents to consider alternative routings via lower-altitude hubs if a passenger’s health status raises concerns. Others may continue to use Addis Ababa, but with clearer instructions from their doctors on how to manage the risks.

What Nigerian Travellers Are Being Urged To Do

Reports on the advisory outline a series of practical steps that Nigerians with health concerns are being encouraged to take before travelling through Addis Ababa. The first is to book a consultation with a qualified medical professional well ahead of departure, particularly for those with known heart or lung disease, blood disorders, severe obesity or poorly controlled chronic illnesses.

During such consultations, travellers can discuss whether high-altitude exposure is advisable, whether medications need to be adjusted and whether additional support, such as portable oxygen, might be necessary. Doctors may also provide written fitness-to-fly notes that can be shared with airlines if special assistance is required at the airport or on board.

The advisory further underscores the importance of carrying sufficient prescription medicine in original labelled containers and keeping it in cabin baggage. Passengers are also being encouraged, according to media reports, to stay well hydrated, avoid excessive alcohol, stand up and stretch during flights and pay close attention to any early warning signs such as unusual chest pain, difficulty breathing, dizziness or confusion.

Publicly available travel health guidance suggests that anyone who begins to feel seriously unwell during a layover should notify airline or airport medical services without delay. Even though the Nigerian advisory does not outline detailed clinical protocols, the overall message is that early intervention can significantly improve outcomes in altitude-related medical situations.

Advisory Not a Ban on Travel to Ethiopia

Despite the stark figure of 16 recorded deaths, Nigeria’s new warning stops short of advising citizens to avoid Addis Ababa altogether. Coverage of the statement makes clear that the federal government is not imposing a prohibition on travel to or through Ethiopia but instead focusing on awareness and risk mitigation.

The advisory notes that many Nigerian passengers transit safely through Addis Ababa each year, and that high-altitude health complications typically affect a relatively small subset of travellers. The concern arises from the severity of the outcomes when problems do occur, as shown by the fatalities logged by Nigeria’s diplomatic mission in 2026.

Regional travel analysts quoted in media reports describe the move as part of a broader trend in which governments are paying closer attention to medical risks associated with aviation, not just security and political stability. With African air traffic recovering and long-haul connections expanding, hubs located at higher elevations are likely to face more frequent scrutiny from public health and foreign affairs officials.

For now, Nigerians planning to fly through Addis Ababa are being advised to weigh their options carefully, especially if they or their relatives have significant health conditions. By seeking medical advice in advance, understanding the implications of the city’s altitude and planning itineraries with their health profile in mind, at-risk travellers can reduce the likelihood of serious complications while still making use of one of the continent’s key air gateways.
