Is temperature check a reliable way to detect coronavirus disease?

There is little scientific evidence to support temperature screening as a reliable method for detection of COVID-19 or other febrile illness, especially if used as the main method of testing.

Temperature readings from temperature screening systems will measure skin temperature rather than core body temperature. In either case, natural fluctuations in temperature can occur among healthy individuals. These readings are therefore an unreliable measure for detection of COVID-19 or other diseases which may cause fever. Furthermore, infected people who do not develop a fever or who do not show any symptoms would not be detected by a temperature reading and could be more likely to unknowingly spread the virus.
