This change in guideline comes at a time when delta variant cases are causing a sharp increase, especially in less vaccinated areas.

“In broadcast areas [de la COVID-19] Importantly, the CDC recommends that fully vaccinated individuals wear masks in public places indoors, ”said Rochelle Walenski, director of the Centers for Disease Prevention and Control (CDC).

Although vaccination against the Delta variant is effective, new data indicate that “in rare cases people are vaccinated” […] The virus is contagious and spreads to others, ”he added.

“These new results are alarming and unfortunately guarantee an update of our recommendation.”

According to CDC statistics, the number of infections is increasing for the most part in the southern United States, but in the Northeast, low, vaccination is advisable.

To prevent the spread of the Delta variant, the CDC recommends that schools wear the mask whether teachers, students or visitors are vaccinated or not.

The CDC last week upheld the May recommendation, saying that vaccinated people should in most cases not wear masks indoors, with some exceptions, including public transportation and hospitals.

The Delta variant, now responsible for 90% of new cases in the United States, has changed the game.

Nearly half (49%) of the U.S. population is vaccinated, but the differences between regions are large.

The latest seven-day weighted average averaged over 56,000 cases, which is close to April levels.

“This does not mean that the quality or protection level of the vaccine has deteriorated,” Eric Cio-Pena, a public health expert at Northwell Health, told AFP.

“This is the solution to the problem, because we have a high level of people who have not been vaccinated.”

Some experts have suggested setting up statistical markers to link mask-wearing responsibilities to the hospital rate, a metric that is considered more reliable than the number of cases per capita.

According to a recent study published in the Scientific Journal Virological, The viral load in the first tests of patients affected by the delta variant was 1,000 times higher than in patients with the first wave of the virus in 2020.

Not only does the Delta variant reproduce faster in its species than previous species, but infected individuals spread the virus more in the air, which significantly increases the likelihood of transmission.

In light of the spread of the Delta variant, last month, Israel gave back 10 days after lifting some masked requirements. Some local communities in the United States, such as Los Angeles County, have done the same.
