The leading pandemic body in the United States has suggested a radical change that will provide relief to those vaccinated against the coronavirus

The U.S. Centers for Disease Control and Prevention (CDC) changed its recommendations on Tuesday to indicate that the nation’s population fully vaccinated against coronavirus can do without a mask outside except in large crowds.

Specifically, people who have been fully vaccinated against the disease may not wear a mask outside if they are walking, running, or cycling alone or with relatives. “There are many situations in which fully vaccinated people do not need to wear a mask, especially if they are outdoors,” CDC director Rochelle Walensky said at a press conference at the White House.

They can also take it off when dining at outdoor restaurants with friends from various family nuclei. In the case of small social gatherings held indoors, the use of the mask with friends and family can be omitted also with the complete schedule or, failing that, if there is a mixture between vaccinated and unvaccinated.

“Less than 10% of infections documented in many studies have occurred outdoors”added the head of the CDC. EFE

On the other hand, as announced by the director of the CDC, Rochelle Walensky, the American authority has recommended that people totally immune to COVID-19 avoid medium-sized meetings. But, if they choose to attend an outdoor event that lends itself to the crowds, like festival or sporting event, the CDC continues to recommend the use of the mask.

For its part, in indoor facilities such as supermarkets, cinemas or museums, the CDC recommends wearing a mask in the same way, the TV station reported. CNN.

Finally, among the recommendations, it also appears that Americans with the full model who live with other people or work surrounded by colleagues they do not have to maintain a 14-day quarantine if they have had close contact with an infected person. They must undergo a diagnostic test for COVID-19, even if they have no symptoms.

More than 140.9 million people received the first dose of the COVID-19 vaccine in the United States, while more than 95.8 million were also inoculated with the second. The United States, the worst-hit country in the world, has so far been the source of more than 32.2 million infections, including more than 572,000 deaths from the disease.

The experts’ view on how coronavirus infections would happen

Currently, the expert consensus believes that the contagion of COVID-19 it is produced mainly by air by droplets of saliva which are suspended when a person coughs or sneezes, but which can also be emitted when speaking, shouting or singing.

For this reason, being in an enclosed space is more risky if there is no adequate ventilation. On the other hand, the air circulates outside and the risk that a person breathes a concentration of virus is less, for example if passing next to an infected person.

There are several studies that support this thesis and show that the vast majority of infections occur when a person comes into contact with an infected person in an enclosed space.
