O BSH is reviewing how Coved-19 is broadcast through air

The World Health Organization has confirmed the existence of increasing evidence that the coronary virus can also be transmitted through tiny particles swimming in the air.

Until recently, O BSH viewed contact with areas infected with coronary as the only way to transmit the infection supported by scientific evidence. Thus, Coddy-19 is transmitted through sprays caused by coughing or sneezing.

That's why O The BSH pointed to washing hands as a key measure of prevention against Ovidius-19.

But they now confirm that “air transmission” cannot be excluded into certain environments. This means that the coronary virus can also be transmitted through tiny particles that form during conversation or breathing. If this evidence is confirmed, it can affect new directions about conduct at home.

How's air transmission?

Air transmission occurs when we absorb a virus or bacteria from particles that can swim in the air for hours. These much smaller sprays can spread into a much larger area. Tuberculosis, flu, and pneumonia are examples of air disease.

O The BSH has acknowledged that there is evidence suggesting this is also possible for coronarys inside and overloaded spaces.

How long does the virus survive the air?

Studies have shown that the coronary can stay in the air for at least three hours. But scientists show that the experiment is conducted in a laboratory that changes in terms of real - life conditions where the results can change.

There are circumstances under which the coronary “spreads super”, which raises the suspicion that pollution through air is a real possibility. In the American town of Mount Vernon in Washington, one person allegedly infected at least 45 others who sang in the same choir.

Some of the infected did not break any of the social distance rules.

A similar incident occurred at the end of January in Guangxi, China, where an infected person is believed to have passed the virus to nine others who ate at the same restaurant.

Scientists say one of the infected customers had been lowered six meters from the infection carrier.

The way a disease is transmitted determines measures taken to prevent its spread. The World Health Organization's current guidelines for Coddy-19 recommend washing hands with hot water and soap for 20 seconds, as well as respecting social distance rules.

But some scientists now argue that while these measures are of great importance, they will not be sufficient against air infections. So far, O The BSH has added nothing new to the current guidelines, but new evidence is currently being assessed.

If confirmed, official advice can be expanded to include the most widespread use of masks and more rigorous distance, especially in cafes, restaurants and public transportation.

The strictest adjustment of air - conditioned facilities could also be brought into question.

What did O Should I reconsider its instructions?

Recently, 239 scientists from 32 countries published an open letter to WHO.

They called on the UN agency to renew its guidelines for the choreographer, in light of air transmission information.

“We wanted to confirm this test”, said Jose Jimenez, a chemist at Colorado University who signed the letter.

This is definitely not an attack on WHO. It's a scientific debate, but we felt we had to go public with it because they refused to listen to the evidence after the many conversations we had with them.

In response to the letter, Benedeta Alegrinz, the technical leader of O The BSH for the prevention and control of the infection said that the evidence of the air-progonvirus transmission in “the descriptions that are packed, closed, poorly ventilated cannot be excluded”.

Anyway, O The BSH said it wanted to see more evidence of this form of infection before making any new decisions.

Another WHO adviser, David Hayman, said the agency expected concrete results from much broader research before adopting a new antivirus strategy.
