The SARS-CoV-2 delta variant now accounts for 83% of new cases in the United States, said Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention, on Tuesday (July 20): I am. Senate hearing..
“This is a dramatic increase from 50% of the week of July 3rd,” Walensky said. “In some parts of the country, especially in areas with low immunization rates, the rate is even higher.”
A total of 161.5 million people, or 48.6% of the total US population, are fully vaccinated. According to CDC data.. However, nearly two-thirds of US counties are vaccinated by less than 40% of their population, Warensky said. “In areas where vaccine coverage is limited, the emergence and rapid spread of highly infectious delta mutants is possible.”
However, cases are also increasing in some areas with high immunization rates, such as San Francisco. According to the state data tracker.. Still, the vast majority of people currently hospitalized in San Francisco with COVID-19 are not vaccinated. According to ABC7 News..
The delta variant (B.1.617.2) was first discovered in India, but is now widespread in more than 100 countries. According to the World Health Organization.. Delta is believed to be approximately 60% more contagious than its predominantly predominant strain, the alpha mutant. Live science previously reported..
In June, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, called the Delta variant the “greatest threat” to US efforts to eliminate COVID-19. Live science previously reported..
“Reason [delta is] Very formidable is the fact that it has the ability to efficiently transmit from person to person in a far better way than any other variant we have ever experienced. ”Now when it comes to the dominant variant He added.
“In areas with low vaccination rates, cases and hospitalizations are starting to increase again,” Warensky said in a hearing. Deaths from COVID-19 in the United States have increased by nearly 48% in the past week, reaching about 239 people per day, she said. “When we know that most of these deaths can be prevented with simple, safe and available vaccines, each death is tragic and even more tragic,” Warensky said.
Current data show that the vaccine acts on circulating mutants in the United States, including delta mutants, and protects people from serious illness, hospitalization, and death. “The message from the CDC remains clear. The best way to prevent the spread of the COVID-19 mutant is to prevent the spread of the disease,” she said. “Vaccination is the most powerful tool we have.”
In the briefing, Fauci reiterated that the vaccines used in the United States are very effective in protecting people from the Delta, especially in preventing hospitalization and death.
Research is currently underway to determine if booster shots are needed to increase the durability of the defense against SARS-CoV-2. “I don’t want people to believe,” Forch said, because the vaccine isn’t effective because there’s such a story about boosters. The durability of its protection.
According to experts, most people who are fully vaccinated with COVID-19 in the United States are strongly protected from the delta variant of the highly infectious coronavirus and may not yet need booster shots. there is. Live science previously reported.. However, immunosuppressed people may need booster immunity as part of their initial vaccination program, Forch said.
At this point, it is “very important” to vaccinate as many people as possible, Forch added.
