The British newspaper, “The Independent”, reported that the BA.2 strain of “Omicron”, spread in 30 US states, and constituted about 3.9 percent of the total new infections.
Scientists note that this strain spreads very quickly, data from the Centers for Disease Control and Prevention shows.
Samuel Scarpino, director of the Center for Pathogen Control at the Rockefeller Foundation, said, “If the strain doubles again and becomes 8 percent, this means that we may face a new wave of “Covid-19″ in the United States.”
“This is what we are concerned about,” he added.
It is believed that the BA.2 strain is more contagious, more rapidly spreading compared to the original strain of “Omicron”, and caused a significant increase in Corona injuries in Denmark.
As for the two things that may mitigate the spread of the new strain, they are vaccination rates and immunity from previous infections.
Nathan, assistant professor of epidemiology at the Yale School of Public Health, said that the new strain will lead to an increase in infections, expressing his belief that it will not reach the wave limit.
“Many of us assumed it would take off as quickly in the US as it did in Europe and become the new dominant entrant,” he added.
Other scientists warn that removing the muzzle will allow the new strain to spread.
