- A popular video in Japan released on May 8 shows quickly a virus can spread between restaurant diners.
- Japanese state broadcaster NHK gathered 10 volunteers to eat as normal in a simulated buffet environment.
- One person was chosen to be carrying the virus, and fluorescent paint was put on to their hand to represent it.
- The 10 people were then left for 30 minutes to get food from the buffet, sit down together, and eat.
- A UV light was then used to lay bare how the paint had spread. Scroll down to watch the video.
- All nine other people, table surfaces, glassware, and serving utensils, bore traces of the paint within minutes, NHK said.
- Three people had traces of the paint on their faces.
- Hiroyuki Kunishima, of the St. Marianna University School of Medicine, told NHK that a "high-touch surface" like tongs or container lids are "harboring danger."
- Two health experts told CNN the lesson to learn was that regular handwashing is key to stopping a virus from spreading.
