Contagious disease, thermopile array, Fever screening system, and temperature measurement.Abstract
Contagious diseases pose a serious threat to lives of people in our contemporary society and one of the predominant symptoms of contagious diseases is fever. Detection of fever is an essential step in identifying subjects who may be suffering from contagious diseases such as Ebola Virus, Avian Influenza, and Severe Acute Respiratory syndrome. This study developed a cost-effective device used to detect fever. TPA81 thermopile array, Arduino Uno, Adjustable stand and LabVIEW software was used to develop the fever screening system. We tested the device on 55 febrile and afebrile subjects using the inner canthi of the eyes as our region of interest and the temperature threshold of 38°C. we achieved the sensitivity of 100%, specificity of 96% and correlation coefficient of 0.97 when we compared our results with the clinical thermometer used for human body temperature measurement. It was also observed that the error difference between the actual temperature of the subjects and the measured temperature by the proposed device was only 0.45°C. In this study, we were able to demonstrate how a simple, cost effective TPA81 thermopile array was used to achieve an efficient non-invasive fever screening system which can be used to screen large number of people.
