Face masks that LIGHT UP under a scanner if you have coronavirus could be used to identify infected people in hospital waiting rooms and airports

Researchers from MIT and Harvard are working on adapting a technology first developed in 2016 to quickly and cheaply detect signs of the Zika virus.

• Sensors in masks are able to detect signs of the virus in saliva after three hours
• When they detect the virus the mask then emits a very faint fluorescent glow 
• This glow can then be picked up by cheap handheld scanners called fluorimeters
• Developers of the masks hope to have them ready for distribution at the end of the summer but say they have a small team so it may take longer than that . MIRROR
