A black light video from Japan is going viral for showing just how quickly the coronavirus — or any germ, really — can spread through touch alone.
Japanese state broadcaster NHK simulated what can happen when people dine in close quarters, such as at a buffet or being served family-style in a restaurant.
The 35-second clip shows 10 people sitting down to eat — including one “infected” person whose palms were coated with a paint that is invisible to the naked eye, but can show up under UV light. It’s supposed to mimic what would happen if the infected person covered a cough with his hands, but then proceeded to serve himself at a buffet and dine in a group without washing or disinfecting his hands.
The video shows all 10 people sharing a water pitcher and serving utensils as they fill their glasses, pile their plates with food, and begin to eat. Everyone is left to dine, go back for seconds and converse freely for 30 minutes.
But once that half hour is up, the black light is turned on — and glowing traces of the “virus” are seen on all 10 people — including three people’s faces — as well as on the table, the plates, the drinking glasses, the serving utensils and the drinking pitcher.
Professor Hiroyuki Kunishima of the St. Marianna University School of Medicine told NHK that a “high-touch surface,” such as the serving tongs or the handle of the pitcher, could be “harboring danger.”
The video was released on May 8, and had been viewed more than 13.4 million times on /zigman2/quotes/203180645/composite TWTR -0.47% by Thursday morning.

Of course, health experts told CNN that this is an “artificial” situation that should also be replicated to show what would happen if the man washed his hands or used hand sanitizer, although it makes a good case for following hand washing guidelines. This simulation also doesn’t include how COVID-19 spreads from droplets shared by coughing, sneezing or even speaking loudly.
