Invisible viruses spread very fast and we do not even realize it. For this reason, NHK, Japan’s national broadcasting corporation, has released a video showing how germs can be transferred to a room packed with people when there’s only one person who’s infected. The experiment tries to show space at a buffet restaurant or on a cruise ship, which, at the start of the pandemic, was considered one of the simplest ways to spread COVID-19 between people. The public broadcaster NHK teamed up with health experts and explained the fast ways that germs and viruses can spread from person to person.
