Malaria Outbreak at Frankfurt Airport Kills Two Workers, Possibly Spread by Plane Mosquito

German health officials and the operator of Frankfurt Airport have confirmed that six airport employees contracted malaria this summer. Four of them have since recovered, but two died from the illness.

According to officials, the likely source of the infection is a mosquito capable of transmitting malaria that may have traveled to Germany aboard an aircraft arriving from a region where the disease is common. Malaria is not typically considered a local threat in Europe, since its spread depends on specific mosquito species and climate conditions, but isolated imported cases — including ones linked to air travel — are occasionally recorded.

What Is Known

All six cases were identified this summer among people working at Frankfurt Airport, one of the busiest air travel hubs in Europe. The exact circumstances of how the infections occurred are still being investigated, though suspicion has focused on the possibility that an infected mosquito entered the country on an inbound flight.

Malaria is a parasitic disease caused by Plasmodium parasites, transmitted to humans through the bite of an infected Anopheles mosquito. Without timely treatment, it can lead to severe complications and death, particularly when diagnosis is delayed because doctors in regions where malaria is uncommon may not immediately suspect it.

German health authorities say they are continuing to investigate the circumstances of the outbreak in order to determine the precise source of infection and prevent similar incidents from occurring in the future.
