Many infectious diseases are most transmittable when the carrier is presenting with fever. We propose a disposable face mask that changes color as an indicator of fever to provide hospitals with a quick and inexpensive method for triaging infected patients while limiting exposure to others. Two blue thermochromatic dyes which transition to white at 89°F and 92°F were mixed with white paint and applied to 5 types of disposable face masks. During trials, a wearer either sat at rest or ran on a treadmill for 20 minutes and images were obtained every 5 minutes with a thermal camera to record surface body temperature. At rest there was no change in body temperature or in mask color. After 20 minutes of running, a 5°F increase in surface body temperature was measured. Only the mask created with the 89°F dye showed a color transition with large white areas apparent post-run. This indicates the ability of thermochromatic masks to measure body temperature and potentially identify febrile patients.
