How fast is the new crown virus spreading in restaurants? Recently, the Japan Broadcasting Association (NHK) and health experts conducted a simulated "hard core" experiment.
According to the released video of simulated virus transmission, ten volunteers participated in the experiment. One of them was an "infected person". His hands were coated with fluorescent materials in an attempt to simulate how the new coronavirus spread indoors.
The volunteers at the scene dine together. After half an hour, the results of the experiment were unexpected: the "virus" on the hand not only touched the volunteer's mouth, but also spread to the table and table cups. In addition, other diners at the same table were also attached to different degrees of "viruses".
NHK TV stated that the experiment proved that if there is no protective measures, the virus can spread quickly. Washing hands, wearing masks and sharing meals can greatly reduce the spread of the virus.
Although such experiments are not new, John Nichols, a clinical professor of pathology at the University of Hong Kong, said they prove how fast the virus spreads, especially without washing hands. However, Nichols also said that the experimental scenario was "artificially" simulated, and the contact itself was emphasized more. Kotaro, an infectious disease expert at Kobe University, agrees.
