The Delta variant causes a strong rise in the number of COVID-19 cases in the United States, leading to a change in recommendations, while there are major outbreaks in areas where vaccination campaigns are lagging behind.

According to CNN, the country’s top health officials met Sunday evening, with CDC Director Rochelle Valensky expected to announce the change at a conference on Tuesday afternoon, the channel and the Washington Daily reported.

The CDC defended its May recommendation last week, saying vaccinated people do not need to wear masks in most situations, with some exceptions, including public transportation and hospitals.

But the Delta variant was a game changer with about 90% of new cases in the United States.

If the vaccines currently on the market are so effective against hospitalization and death, more cases are found among those who have been vaccinated.

Some experts have suggested setting up statistical markers to link mask-wearing duties to hospital admission rates, which is considered more reliable than the number of individual cases.

According to a recent study by the scientific journal Virological, the virus load in the first trials of patients with delta variability is 1,000 times higher than in patients with the first waves of the virus by 2020.

The delta variant not only reproduces faster within its host than previous strains, but also significantly increases the chance that infected people will spread the virus over the air.
