**2.11 Use of thermal scanners and hand dryers**

High fever is one of the common symptoms of COVID-19. Thermal scanners can detect people who have high body temperature or fever but not COVID-19 [10]. It takes about 1–14 days for the virus to incubate and to show observable symptoms, hence, thermal scanners may not detect high fever in asymptomatic patients. There are diverse types and causes of fever. It is important to seek proper medical care or go for testing when a very high fever is observed. Hand dryers cannot kill COVID-19 but are only recommended for use to dry hands after thorough and frequent hand washing.
