In times of increasing mobility, infections don’t stop at national borders either. Whether ebola, SARS, or coronavirus: no one wants to imagine the consequences of an epidemic or even a pandemic. That’s why it’s in the interest of public health to identify risk persons in large groups of people early. The operators of heavily frequented facilities such as airports, shopping malls, or sports stadiums carry a special responsibility for disease prevention.

An important indicator of infection is increased body temperature (compared to other people in the immediate surroundings), generally known as fever. Thermography is the ideal method for scanning not just individuals, but also large flows of people. To do this, the temperature at the inner corner of the eye is measured, and an alarm is triggered if it deviates. This allows persons with increased body temperature to be identified quickly and reliably, and to be isolated for more exact testing.
