(CNB News) – 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 an “infected” person. A fluorescent substance only visible under black light is applied onto that person’s hands, representing germs from a cough or a sneeze. Each participant then goes about the buffet as they normally would, not considering a potential contamination.

At the end of the video, the participants are cast under black lights illuminating where the “infection” has spread.
“The substance, used to signify the germs, can be seen on food, serving utensils and platters, and even on the faces of some of the participants.

Japan has had 16,049 confirmed Covid-19 cases and 678 deaths, according to Johns Hopkins University data. More than 4.3 million cases of Covid-19 have been recorded worldwide, including at least 297,000 deaths.
