Thermal screening to spot people infected with coronavirus is more reliable when scanning the eyeball and fingertip than taking body or forehead measurements. Experts in human physiology published a scientific article on the usefulness of thermometers which scan a person's skin to detect a fever. They say the current process is fundamentally flawed and produces a large number of false negatives, as well as some false positives, and also because not all people infected with the coronavirus develop a fever. A fever is defined as a temperature of greater than or equal to 100.4F (38 C) if spotted outside of a healthcare environment. In healthcare settings, such as a hospital, a fever is technically defined as anything greater than or equal to 100.0F (37.8 C).
