Abstract

Infrared thermographs (IRTs) have been used for fever screening during infectious disease epidemics. However, their performance is inconsistent in literature, due to wide quality/implementation variations. We overview standards and FDA guidance for IRT performance evaluation, implementation, and regulation policies. Additionally, we present results from a large-scale clinical study of fever-screening IRTs and discuss impact of consensus guidelines and facial measurement location on performance. We found that: high-quality IRTs implemented according to international standards can help to accurately measure temperature; current standards can be improved to further enhance IRT performance. Overall, fever screening is only one element in infectious disease detection.
