Liu, C.C., Chang, R.E., and Chang, W.C. (2004). Limitations of Forehead Infrared Body Temperature Detection for Fever Screening for Severe Acute Respiratory Syndrome. (Abstract only.) Infection Control Hospital Epidemiology. 25(12):1109-11.
The authors investigated alternative measurement methodology for infrared body thermometry to increase accuracy for outdoor fever screening during the 2003 SARS epidemic. They found that temperature by ear was a more accurate measurement than forehead body surface temperature. This has implications for fever screening interventions for emerging infectious diseases.
