The new variant accounts for more than 80% of new cases of infection in the United States.
The Centers for Disease Control and Prevention (CDC) did not revise their recommendations on wearing masks, despite the spread of a more contagious strain of coronavirus, which is increasing the number of cases of infection in the United States, agency director Rachel Walensky said at a press conference on Thursday.
Walensky declined to specify whether the CDC is considering changing the rules. In May, the recommendations were relaxed, and fully vaccinated people were allowed not to wear masks in most public places.
According to Walensky, the average seven-day incidence rate in the country is 53 percent higher than in the previous week. The Delta variant, which was first detected in India, currently accounts for more than 80 percent of new infections in the United States. This strain has been detected in more than 90 countries.
Walensky also said that some hospitals in the United States have reached the capacity limit, as the number of cases of COVID-19 infection continues to grow.
The increase in the incidence is concentrated in regions with a lower level of vaccination. Florida, Texas, and Missouri account for 40 percent of all new cases nationwide, with about one in five new cases occurring in Florida, White House Director Jeffrey Zients said.
According to him, the United States will continue to distribute tens of millions of vaccines against COVID-19 worldwide.
Anthony Fauci, the chief infectious disease specialist of the United States, said that people who received the Johnson & Johnson vaccine have no reason to get an additional vaccination with Pfizer or Moderna vaccines to protect themselves from new options.
The CDC and the FDA are studying the data to find out whether there is a decrease in immunity in vaccinated people and whether revaccination is necessary in this case.
