A third person has died from malaria in a rare cluster of locally acquired infections linked to Frankfurt Airport, German authorities said on September 17, 2026, raising the total number of fatalities in the outbreak to three.
On September 15, Frankfurt health authorities reported two additional malaria cases among residents of Schwanheim, a district close to the airport. One of the two patients later died at a Frankfurt hospital.
Authorities have stressed that the outbreak does not indicate widespread transmission among the public. Malaria is transmitted through the bite of an infected mosquito and is not spread directly from person to person.

Airport Malaria in Europe, 1969–2024
How the Cluster Developed
- Early July 2026The first five cases emerged among Frankfurt Airport employees, who were diagnosed with malaria tropica, the severe form of the disease caused by the parasite Plasmodium falciparum. The Robert Koch Institute said the cluster was most likely associated with an infected mosquito imported by air.
- Mid-August 2026A sixth airport worker was diagnosed. Of the six workers, two later died, while the others were treated in hospital.
- September 15, 2026Two new cases were announced among residents of Schwanheim, living within about 5 km of the airport. Neither had travelled to a malaria-endemic country or worked at the airport. According to the ECDC, their symptoms began in early September.
- September 17, 2026One of the two Schwanheim patients died at a Frankfurt hospital, according to the city’s health department and University Hospital Frankfurt, bringing the total number of deaths to three.
What Is “Airport Malaria”?
German health authorities believe the infections were caused by an infected Anopheles mosquito transported into Germany on an aircraft or in luggage from a malaria-endemic region. Such incidents are known as “airport malaria” and are extremely uncommon in Germany.
The RKI noted that airport-associated malaria can be particularly difficult to identify, because patients who have not travelled abroad may not initially be suspected of having the disease.
Investigation at the Airport
Fraport, the airport operator, has installed mosquito traps around the site, with captured insects sent for laboratory analysis. Samples have been examined by specialists in tropical medicine in Antwerp, Belgium.
Authorities are seeking to determine whether the outbreak was caused by a single imported mosquito or more than one insect, and to establish its origin.
Reminder for Doctors
Health officials have reminded doctors in Frankfurt and surrounding areas to consider malaria when treating patients with unexplained fever, even when there is no recent travel history. Early diagnosis is particularly important in cases of P. falciparum, which can progress rapidly and become fatal if treatment is delayed.
Advice for People Near the Airport
The Frankfurt Health Department has urged people living or working near the airport to seek medical attention if they develop symptoms such as:
They should also inform doctors of their proximity to the airport, so that malaria can be considered even without a recent travel history.
A Rare but Recognised Risk
The RKI has described airport malaria as a particularly rare phenomenon in Germany. A previous airport-associated malaria incident was recorded at Frankfurt in 2023, while a European review covering cases between 1969 and 2024 identified only 145 cases of airport- or luggage-borne malaria across Europe, including nine in Germany.
The outbreak highlights a rare but recognised risk of international air travel: infectious mosquitoes can occasionally survive long enough to be transported thousands of kilometres from endemic regions, creating isolated cases of diseases that are otherwise not normally acquired in Germany. German authorities continue to monitor the airport and nearby communities while laboratory investigations continue.
