| Research: Keeping a safe distance of 2 meters without wearing a mask or not effective epidemic prevention measures |
China News Service, November 29.
According to the Greek “China Greek Times” report, a recent study by the University of Cambridge in the UK showed that during the new crown epidemic, people are not wearing masks and only requiring people to maintain a distance of 2 meters, which may not be effective.
Local measures, because the new coronavirus can easily spread in the air
.
According to reports, a research team led by Epaminondas Mastorakos, a professor of applied thermodynamics in the Department of Engineering, conducted a study, and the results showed that patients carrying the new coronavirus without wearing a mask, even in an open space , Keeping a distance of more than 2 meters from others can still transmit the virus to others
.
A related article has been published in the journal Fluid Physics, which uses computational models and simulations to study the propagation of cough droplets
.
According to the report, scientists emphasized that keeping a safe distance is not an effective protective measure
.
As winter approaches, we need to accelerate the progress of the new crown vaccination work.
The report pointed out that in the early stage of the new crown epidemic, people focused on hand washing and surface disinfection of objects, but people soon realized that the new crown virus is mainly spread through the air
.
The new crown virus not only spreads through coughing or sneezing, but even brief conversations and exhalations can spread the virus
Mastolacos is an expert in fluid mechanics.
During the epidemic, he and his colleagues established various models of the spread of the new coronavirus
.
This new study shows that when patients carrying the new coronavirus cough without a mask, most of the larger droplets will quickly fall on the surface of nearby objects, but the smaller and lighter droplets will be in the air.
He said that due to differences in speed, temperature and humidity, the spread of droplets from coughing is also different
.
Finally, he emphasized: "We are all looking forward to the end of the epidemic, but the virus is still with us.
Therefore, we strongly urge people to wear masks indoors.
We should not expose ourselves to danger
.
"
According to reports, on the evening of November 28, local time, the National Public Health Organization of Greece announced that there were 3823 new confirmed cases of new crowns in Greece in the past 24 hours and 96 new deaths from new crowns that day
