CNN health | Black light experiment shows how quickly a virus like Covid-19 can spread at a restaurant

(CNN)  A viral video from Japan aims to show how easily germs and viruses can spread in restaurants when just one person is infected.

The experiment simulates the atmosphere at a buffet restaurant or on a cruise ship. It was conducted by the public broadcasting organization NHK in conjunction with health experts.

The video shows 10 people coming into the restaurant, with one singled out as the “infected” person. Each participant goes about the buffet as they normally would, not considering a potential contamination. —more
