An experiment using black light has shown how quickly germs and viruses can spread in restaurants when only one person is infected.

Hundreds of tourists have been infected with COVID-19[female[feminine on a cruise ship in Japan, with a buffet on the ship it’s believed to be where most people got it.

The new experiment simulates how far a virus can spread in a buffet place by using paint invisible to the naked eye to represent the virus.

Produced by the Japanese public broadcaster NHK in association with infection experts, the video shows 10 people entering the restaurant, one of whom was “infected” with the paint.

The group sits at a table before going to the buffet table to prepare dishes on their plates before sitting down to eat.

The black lights are then on, illuminating where the “virus” has spread from one person.

The paint, which glows white under the light, is visible on the hands of all participants and on the faces of most of them, especially around their mouths.

It is also found on food, tongs, the lid of food containers, the handle of a jar, all dishes, the tablecloth and the bill.

John Nichols, professor of pathology at the University of Hong Kong, told CNN the video “really highlights the need for what people said about hand hygiene to stop the spread of disease.”

The video was released after research from Stanford University found that talking transmits the virus.

The louder people speak, the more dispersed the droplets, the study found.

The researchers said that with only one minute of speech, at least 1,000 infected droplets remain in the air for more than eight minutes.

These can then be inhaled by other people, triggering a new COVID-19 infection.
