Revealed newspaper “Daily Mail” the British, he can pass the corona virus Covid-19 Among the people in face masks at a distance of three feet, where the study shows how the cough causes the penetration of drops of saliva to face, swallowed researchers have a computer model to simulate the flow of saliva from a cough.
Transmission of the virus from the gag.
They found, that even with the presence of drops of saliva still able to escape from the mouth, when they cough, people in the channel becomes less effective and allows the corona virus out there more, making the friction law of cooling Social 6 more feet protection.
Warned a new study, that the MERS-CoV coronavirus, able to move between two people standing 3 feet, even though one of them was wearing a face mask class surgical, as University researchers found “Nicosia” in Cyprus, that the masks become less effective when they cough, where people frequently.
MERS-CoV is transmitted through the gag.
Scientists say the findings “alarming”, and stress the importance of keeping the base of the long distances of 6 feet in its place even when you wear the masks.
It comes at a time when the British Prime Minister, Boris Johnson, under increasing pressure from industry, especially tourism, to ease the guidelines, this time they used a computer model accurate to draw interference patterns generated when a coughing person wearing a mask.
They took into account possible weather conditions, disturbance of the air, and even the temperature of the skin and mouth when you cough, the researchers conducted a numerical simulation to interpret the interactions of the droplet with the filter porosity in the surgical mask.
The newspaper said, the results are alarming, wrote the authors, even when wearing a mask, some drops to go a great distance during periods of mild cough.
Based on tests to a surgical mask record showed the efficiency of an initial amount of about 91% when you prevent the drops from escaping, for the purposes of visualization, the zoom droplet larger 600 size compared to their actual size, making it easier to follow.
Said dress: “change the sizes of the droplet, and require constantly during the sessions of coughing as a result of the interactions of the many with the mask and the face,
