An airport worker has died in Germany after contracting malaria from a mosquito believed to have been carried onto a plane, with five other staff members hospitalized. Frankfurt Airport has implemented mosquito traps throughout its facilities as part of an effort to identify the species and origin of the insects responsible for this rare outbreak.
The Robert Koch Institute, Germany's federal agency for disease control and public health, stated that an imported Anopheles mosquito, transported via aircraft, is the likely cause of the infections. The five affected employees are currently receiving medical treatment for what is termed 'airport malaria'. Initial reports in July indicated four infected workers at Germany's busiest airport.
According to the Robert Koch Institute, the employees contracted the disease between July 4 and July 6. Airport malaria, also referred to as suitcase or Odyssean malaria, occurs when an infected mosquito is transported to a malaria-free region on an aircraft or within luggage and subsequently bites an individual.
The rarity of this condition can lead to delayed diagnoses, potentially increasing the severity of symptoms. Fraport, the airport operator, confirmed that a total of six employees contracted airport malaria in connection with their work. The company has provided extensive information to all staff and urged them to seek medical consultation if they experience any symptoms, such as high fever, sweats, chills, headaches, abdominal pain, loss of appetite, or muscle aches. Employees are advised to inform their doctors about their airport employment and the reported cases of airport malaria to ensure appropriate medical assessment and treatment.
Mosquitoes captured in the newly installed traps will undergo genetic analysis by the Institute of Tropical Medicine in Antwerp, Belgium, to determine their species and origin. Fraport expressed deep sadness over the loss of their colleague and extended thoughts to the employee's family and friends.
The Robert Koch Institute noted that airport malaria cases in Germany are infrequent, with the last known instance at Frankfurt Airport occurring in 2023. The absence of a recent travel history for affected individuals can contribute to diagnostic delays, which in turn can lead to a more severe course of the disease, as stated in its epidemiological bulletin.
Malaria was eradicated in Western Europe in the 1970s, and nearly all subsequent cases have involved travelers returning from regions where the disease remains prevalent. However, in endemic areas, malaria is a significant cause of mortality, particularly in sub-Saharan Africa. Effective treatments are available, and early diagnosis typically results in a full recovery.
The Frankfurt Health Department is continuing to monitor the situation, and Fraport maintains regular contact with the responsible authorities.
