Temperature controls our quality of life and the measurement of different types of temperatures are inter-related, especially when utilizing infrared thermal imaging for human temperature screening. The average normal body temperature is generally accepted as 98.6°F (37°C). The flow of energy to and from the skin determines our sense of hot and cold. Severe acute respiratory syndrome (SARS) poses a serious threat to the general population. This means a greatly reduced risk of contagion, without the need for probe covers. If it is outside that temperature, the standard accuracy of a thermometer is plus or minus 2° Fahrenheit.
