It is so easy to forget just how quickly viruses can spread when they’re invisible.
For this reason, NHK, Japan’s national broadcasting corporation, has shared a video showing how germs can be transmitted to a room full of people when there’s only one person who’s infected.
The experiment aims to simulate a space at a buffet restaurant or on a cruise ship, which, at the beginning of the pandemic, was considered one of the easiest ways to spread COVID-19 between people. The public broadcaster NHK teamed up with health experts and demonstrated the fast ways that germs and viruses are transmitted from person to person.
The video shared on May 8, was designed to show how far a virus can be transmitted from an infected person at a restaurant. The experiment was created with the help of experts from Kawasaki’s St. Marianna University School of Medicine. It involved 10 people eating in a buffet-style restaurant. Before people could serve themselves, the researchers applied a fluorescent lotion to the hands of one of the people participating in the experiment.
The fluorescent lotion, which would show up later under a UV light, simulated viral droplets from a cough. Then, the subjects of the experiment were allowed to dish up food from the buffet trays.
The subjects of the experiment were totally shocked – the lotion had gotten everywhere. It was on the hands of every participant, plates, tongs, drink pitchers, and even on some people’s mouths.
