According to a new study by researchers from the University of California, San Francisco, face masks can reduce the amount of virus that enters the human body, which means that the disease will not be severe. In England, face coverage is mandatory on public transport, and will become so in stores and supermarkets as of July 24.
The modern American research is to be published in the Journal of Internal Medicine, but it has been previously circulated by researchers. "A person gets a lower dose of the virus if he wears a mask and is exposed to" Covid 19 ", and it is very likely that he will have mild symptoms or none at all," said Monika Gandhi, an infectious disease expert at San Francisco General Hospital. ".
She said that the results of the study urges the authorities to move forward in their recommendations to wear masks, "the study indicates the need to wear a face mask to control infection and reduce the severity of the disease." She indicated that this would include wearing masks in the workplace, where not every employee has a private office.
Experts say that receiving a lower initial amount of "corona" gives the immune system a better chance to fight the disease. The new study extracts evidence that masks reduce the amount of viral droplets that reach the wearer's airways.
One study, conducted in experimental rats, showed that animals exposed to the virus had milder cases of "Covid 19" when they were wearing a surgical mask. Medical reports say that when the epidemic broke out on cruise ships, where passengers wore masks, the infection rates were usually without symptoms or a mild infection, at high rates.
