Thermal cameras are used to detect people with fever and to conduct further examinations of whether they carry disease by separating them from other people. Of course, it is not possible to detect patients without fever or those who are still in the incubation phase and who are not yet sick. However, since there is not yet another fast and more effective method that can be used for scanning purposes, all countries use thermal cameras. In addition to the thermal cameras, passengers from the risky area are informed in different languages on the aircraft, and information brochures prepared in foreign languages are distributed at the passport points.
