Two airport workers have died and four others were infected, likely due to a mosquito imported on a flight.

The short version

  • Six people working at Frankfurt airport contracted malaria tropica since last month, resulting in two deaths.
  • The Robert Koch Institute suspects the infections were transmitted by an imported Anopheles stephensi mosquito.
  • Health officials have placed mosquito traps around the airport and urged local doctors to monitor workers for unexplained fevers.
  • The risk to the general public remains low, as human-to-human transmission of malaria is not possible.
