An alarming video from Japan that used a black light demonstrates how quickly the coronavirus can spread aboard a cruise ship or in a restaurant when just one person is infected.
In an experiment conducted by public broadcaster NHK in collaboration with infectious disease experts,10 people were asked to serve themselves as usual at a buffet, according to Forbes.
Invisible fluorescent paint — visible only under a black light — was applied to the palm of one of the subjects, who was tapped as the “infected” person and coughed into his hand.
