According to this article, thermal scanners cannot reliably tell the difference in a temperature and other common causes.
"While the systems can sense elevated skin temperatures, they aren’t precise enough to tell whether someone has a fever or something else: The warmth of a person’s skin is often quite different from their core body heat. People with heavier builds, health conditions or hot flashes can trigger the system’s alarms; so, too, can anyone just walking in from a hot car or parking lot. "
