The study indicated, according to the “Business Insider” website, that people were infected with the virus after eating food and were sitting at adjacent tables in a restaurant without windows in the Chinese city of Guangzhou.
The researchers, who co-wrote the study, believe that the restaurant’s air conditioner carried the virus-carrying spray from a 63-year-old woman who was present at the restaurant.
It is believed that the symptoms of the disease did not appear on her and she was not originally aware of her infection.
The researchers were surprised by the results of the study, considering that the corona virus particles are heavy and difficult to travel long distances through the air, and may not exceed one meter.
The researchers recommend that it is necessary to increase the distances between tables and improve ventilation inside restaurants in order to prevent the spread of the virus in the future.
According to the Business Insider website, the researchers’ results are evidence that the situation in restaurants will not return to what it was before the emergence of the new Corona virus.
And he adds that restaurants departments may in the future set instructions to limit the spread of the virus, including setting a specific time for customers to finish eating, working with less capacity and asking employees to wear masks, as well as placing air-conditioning vents in places far from customers.
William Schaffner, professor of infectious diseases at Vanderbilt University, says the research results are a good source to help understand the future reopening of restaurants.
Most of the countries that suffer from the Corona epidemic decided to close cultural centers, bars, restaurants and gyms, as well as prevent concerts and sporting events that usually witness large gatherings, to limit the spread of the virus.
The measure caused millions of dollars in material losses and high unemployment, which prompted some countries, including the United States, to reconsider these decisions by lifting some restrictions on restaurants and some shops.
