Malaria is a serious disease caused by a parasite and is most commonly spread to people through the bite of an infected mosquito, according to the Centers for Disease Control and Prevention (CDC).

Early symptoms can include fever, chills, headache, muscle aches and fatigue, the CDC said.

The disease can become severe or deadly if it is not diagnosed and treated quickly.

Mosquito traps have also been installed at the airport , according to the company.

Mosquitoes caught in the traps will undergo genetic analysis by the Institute of Tropical Medicine in Antwerp, Belgium, to determine their species and origin, Fraport said.
