The Delta variant of Covid-19, or B1.617.2, was first detected in India in October and has spread to 62 countries, the World Health Organization recently said.
“Folks, the Delta variant, a highly infectious Covid-19 strain, is spreading rapidly among young people between the ages of 12 and 20 in the UK. If you are young and have not yet received the vaccine, it really is time. It’s the best way to protect yourself and your loved ones, “Biden tweeted Tuesday.
Dr. Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), said that the Delta variant accounts for more than 6 percent of cases that are sequenced in the U.S. The true number is likely to be higher, as the US is running the genetic sequence in a fraction of the cases.
The variant has become the dominant strain in the UK, accounting for about 60 percent of new cases. It is now more prevalent than the Alpha strain, previously called the B.1.1.7 strain, which was first identified in the UK, and transmission is peaking in people between the ages of 12 and 20, said Dr. Fauci at a press conference on Tuesday. .
“In the UK, the Delta variant is quickly emerging as the dominant variant. It is replacing the B.1.1.7,” Fauci said. “We cannot allow that to happen in the United States,” he told CNBC.
President Biden has set a goal of giving at least one vaccine injection to 70 percent of Americans by July 4.
Last week, health officials in Britain warned that the Delta variant of Covid-19 has now become the dominant variant of concern in the UK and may also carry an increased risk of hospitalization.
