A Frankfurt Airport worker died from malaria after an outbreak killed five others.
The outbreak was triggered by mosquitoes allegedly arriving on an inbound flight from a malaria-endemic region.
German public health officials have set up traps at the airport and are analysing captured insects to identify species and origin.
The Robert Koch Institute warned that delayed diagnosis is common in Germany because malaria is atypical there, and the disease can be severe when missed.
This is the third known case of airport malaria at Frankfurt Airport, underscoring the need for vigilance among workers and travelers.
If you work at an international airport or travel overseas, be aware of mosquito exposure and seek medical advice if you develop fever, chills, or flu-like symptoms.
The airport operator Fraport has urged all employees to monitor their health and to contact a doctor immediately if symptoms appear.
During the investigation, blood samples from the affected workers are being examined to determine if a single mosquito or multiple bites caused the infections.
