Two workers at Frankfurt Airport have died after contracting malaria from mosquitoes believed to have arrived on incoming flights, city health authorities and airport operator Fraport confirmed on Wednesday.
The first death occurred in early July, with the cause identified only after the patient’s death, according to the Frankfurt health authority. A second worker died in August. In total, six employees were infected with *Plasmodium falciparum*, the most dangerous form of malaria, while working at the airport. The remaining four have been treated and are recovering, the authority said.
Germany’s Robert Koch Institute (RKI) stated that the infections were likely transmitted by an *Anopheles* mosquito imported by aircraft. The institute noted in its Epidemiological Bulletin that the affected individuals fell ill between July 4 and 6, 2026. The RKI added that such "airport malaria" cases are rare but can lead to delayed diagnoses because doctors may not immediately suspect the disease in non-endemic regions.
Fraport has installed mosquito traps at the airport, and captured specimens are being sent to the Institute of Tropical Medicine in Antwerp, Belgium, for genetic testing to determine their origin, a Fraport spokesperson said. Frankfurt health department head Peter Tinnemann stated that the mosquito responsible was likely already dead and that the risk to the general population was "negligible," as malaria cannot spread directly between humans.
The RKI reported that Germany’s last airport-linked malaria outbreak occurred in 2023, also at Frankfurt Airport. Malaria, a mosquito-borne disease caused by parasites, typically causes symptoms such as fever, chills, nausea, and headaches. While treatable if detected early, it remains a major global health threat, causing hundreds of thousands of deaths annually, primarily in sub-Saharan Africa.
Frankfurt health officials have provided comprehensive information to all airport staff and urged them to seek medical attention if symptoms appear. The investigation into the source of the mosquitoes and the exact transmission path remains ongoing, with laboratory results expected in the coming weeks.
