Highlights |
• | Non-contact infrared thermometers underestimate body temperature. |
• | Outside temperature, humidity, and wind correlate with infrared temperature. |
• | Environmental effects are reduced with longer inside distances to screening. |
• | Non-contact infrared thermometers may not screen appropriately for fever. |
Abstract |
Infrared temperature measurement is a common form of mass screening for febrile illnesses such as COVID-19 infection. Efficacy of infrared monitoring is debated, and external factors can affect accuracy. We determine that outside temperature, wind, and humidity can affect infrared temperature measurements and partially account for inaccurate results.
