Large-scale use of face masks in any area can significantly reduce the number of new cases of corona virus in a few days.
This was revealed in a medical study in Germany.
A study published in the medical journal Proceedings of the National Academy of Sciences examined the effects of a face mask ban in a German city.
The results showed that making the use of face masks mandatory reduced the rate of new cases in the German city by 45% within 20 days.
The research further strengthens the evidence that face masks are a cheap and effective way to prevent the spread of Code 19.

The data available on the number of publicly available cases in the German city of Gina, where the use of face masks was made mandatory in the first week of April.
The researchers found that the number of new cases dropped to almost zero in the weeks following the ban, and that the use of face masks was made mandatory in all German states by the end of April.
Klaus Waldy, a professor at Jonas Gutenberg University who was involved in the study, said it was the first study to examine the effects of face masks on a population level.
The study found that the use of face masks could reduce the number of new Code 19 cases by 15 to 75 percent in just 20 days, depending on the region.
The decline in new cases was most noticeable in people over 60 years of age.
The researchers explained that the results may be different in other regions due to climatic conditions and local laws.
He added that testing rules were the same everywhere in Germany, so he did not examine the differences in testing or the types of face masks.
According to researchers, working on such research reports in other countries will show the extent to which face masks can reduce cases in different situations.
Last week, the World Health Organization (WHO) updated its recommendations on face masks in the wake of a new wave of corona viruses.
Earlier in June, the World Health Organization issued recommendations on face masks, urging governments to use face masks on everyone inside and outside public places, especially in areas where the risk of the virus is high. ۔
In a more detailed recommendation last week, the WHO said that in areas where the virus is spreading, all people 12 years of age or older should wear face masks for poor ventilation in shops, offices and educational institutions. Must use in case of.
According to the recommendations, in places where the ventilation system is not good, face masks should be used inside the houses when guests come.

The recommendations state that face masks must be used outside and inside well-ventilated areas when it is not possible to maintain a physical distance of at least one meter.
The WHO said face masks protect against the spread of the virus rather than disease, and that other precautions, such as hand washing, should be followed.
The World Health Organization said that in areas where code 19 is spreading, everyone should use medical masks in medical centers.
This restriction should also apply to people visiting these centers, the slightly ill, the cafeteria and staff rooms.
The World Health Organization (WHO) said medical personnel should use N95 masks if possible during the care of Code 19 patients.
The recommendations further say that those who do strenuous physical exercise should avoid wearing face masks, especially those with asthma, as they may face some risks.
According to the World Health Organization, proper ventilation in the gym, physical distance and cleanliness of most touching objects should be taken care of or temporarily closed.
The WHO’s recommendations came after the US Centers for Disease Control and Prevention (CDC) last month updated its recommendations on face masks, saying that cloth face masks actually provide bilateral protection. That is, both the wearer and the people around him.
The US agency said in its guidelines that those wearing masks protect themselves from the viral particles in the air emitted from other people’s mouths.
The CDC said that multi-layered and multi-threaded fabric masks. Single-layer and low-threaded masks provide more than 19 codes of protection.
According to the agency, in some cases, these masks even filter out about 50% of the small particles in the air.
In the new guidelines, the CDC cites a number of research reports on the bilateral protection of face masks.
The CDC said the benefits of face masks increase when most people in a community use them.
In fact, mandating the use of a face mask could help prevent future lockdowns, along with other precautions to ensure social distance, hand hygiene and proper drainage, the agency said.
Earlier, several research reports found that mandating the use of face masks significantly reduces the number of new cases.
