  • CDC admits that you have to wear a double mask to avoid the spread of the coronavirus
  • Researchers developed a laboratory experiment
  • But, health authorities did not recommend its widespread use

The CDC does not extend the wait any longer and admits that you have to use a double mask to avoid the contagion of the coronavirus, according to a publication by the AP news agency and the New York Times.

Were researchers who determined that wearing two masks is better than just one to stop the spread of COVID-19, but health authorities did not recommend their widespread use.

The U.S. Centers for Disease Control and Prevention (CDC) reported Wednesday the results of a experiment that separated two artificial heads nearly 2 meters (6 feet) apart to check how many coronavirus-sized particles, spewed out by one, were inhaled by the other.

The researchers found that wearing a cloth or surgical mask blocked 40% of the particles that made their way towards the head that was inhaling. When a cloth mask was worn over a surgical one, up to 80% of the particles were blocked.

If both heads were double-masked, more than 95% of the particles were blocked, said Dr. John Brooks of the CDC.

“The first challenge is to get as many people as possible to wear masks and for those who wear them, it’s to help them get the best benefit,” Brooks said.

The study had many limitations: The researchers used one brand of surgical mask and one type of cloth mask, and it is not clear if the results would be the same with all products, but the study echoes previous research indicating that two masks they are better than one or none.

Some Americans have already started wearing double masks. Experts believe that is due, at least in part, to concerns about new strains that have been discovered and are spreading more easily.

The recommendations of health authorities have evolved throughout the pandemic.

When the COVID-19 crisis began and the masks disappeared from stores, the authorities advised against their use. “Seriously folks, STOP BUYING MASKS!” Tweeted nearly a year ago then-United States Public Health Director Jerome Adams.

Two months later, after it became clear that infected people with no symptoms could spread the virus, the CDC began recommending that people wear face masks in public.

The use of face masks has increased and in some places they are mandatory, but many Americans continue not to use them.

One in 3 Americans rejects COVID-19 vaccine

About one in three Americans say they will or may not be vaccinated against COVID-19, according to a new survey.

Experts say this is disappointing news if the country hopes to achieve herd immunity and defeat the epidemic.

The Associated Press-NORC Center for Public Affairs Research poll found that while 67% plan to get vaccinated or have already done so, 15% flatly said they will not and 17% say it is the most likely. Many expressed doubts about the safety and efficacy of the vaccine.

The survey indicates that skepticism persists in significant proportion after a month and a half of a vaccination campaign in which few or no side effects have been recorded among those vaccinated.

It found that resistance is greatest among young people, people without college degrees, black Americans, and Republicans.
