According to Centers of Disease and Control (CDC), the most common symptom that confirmed COVID-19 patients experience is fever (83-99%), followed by cough (59-82%), and fatigue (44-70%). Among some COVID-19 common symptoms, fever is the most common (83-99%) yet is detectable with the help of technology. Thermal imaging scanner helps to prevent the spread of the disease by detecting individuals with elevated body temperature in a high-traffic places such as airport, office building, supermarket, etc. Experts agree that the technology cannot directly identify COVID-19, but it helps to identify and filter out potential “high-risk” individuals. Thermal imaging scanner serves as a front line screening tool, usually placed at a point of entry, where it detects the body temperature of a group of people at once, contrary to gun thermometer where people need to line up and get checked one by one. In addition, thermal imaging scanner is designed to accurately detect temperature from distance, without close human contact, which reduce the risk of COVID-19 transmission.
