Airport Fever Scanning

Airport fever scanning


Recent epidemics of influenza such as H5N1 have highlighted the role of modern air travel in the global spread of infectious disease. Many airport authorities and governments have installed thermal infrared scanning cameras at several airports to look at passengers for signs of fever. Typically, the skin around the inner corner of the eyes becomes noticeably warmer than the rest of the face in fever. The screen shows a thermal view of the three passengers at left. On the screen shown here colours represent temperatures, with blue and green being coolest and red and white being hottest.
