A Japanese video footage presents an experiment that proves how easily viruses and bacteria can spread in restaurants if only one person is infected. The experiment simulates the atmosphere of a buffet restaurant aboard a cruise ship. NHK, a Japanese public service broadcaster, organized the experiment with the involvement of health experts. The video simulates 10 people arriving at the restaurant, one of whom is “infected.” Fluorescent material visible under black light is applied to the person’s hands, showing germs of coughing or sneezing. After that, each participant walks the buffet in the usual way and does not take into account possible contamination. At the end of the video, participants are exposed to black lights that illuminate the spread of the “infection.” The germ marker material can be seen on the dishes, dishes and bowls, and even on the faces of some of the participants:
“Although these types of experiments are not new,” said John Nicholls, a clinical professor of pathology at the University of Hong Kong, “to show how quickly the virus can spread, especially if people don’t do hand washing.” “What the video showed is that it spreads very effectively to surfaces and people,” Nicholls told CNN, “and I think it really shows the need for proper hygiene to stop the spread of disease.”
The ViroFighter intelligent autonomous UV disinfection robot can properly disinfect not only the air but all objects and surfaces in its path in seconds and kill all bacteria and viruses. Using the ViroFighter robot, we can effectively combat all types of infections and provide a sterile environment not only in restaurants, but in any interior where people appear frequently. At the same time the ViroFighter robot automates the otherwise very resource-intensive and laborious daily disinfection processes, therefore can be a cost-effective solution to fight the Covid-19 and other pandemics.
