A new subvariant of SARS-CoV-2, this one dubbed BA.2, has taken over from all the other strains in the U.S., according to the U.S. Centers for Disease Control and Prevention (CDC).
According to a recent article in the Scientific American, BA.2, currently “accounts for nearly 55 percent of all new SARS-CoV-2 infections in the U.S., according to latest data from the Centers for Disease Control and Prevention.”
The good news, according to the outlet, is that the “disease symptoms caused by BA.2 are not more severe than those caused by BA.1 in vaccinated people or people who were previously infected with SARS-CoV-2.” This data came from Ram Sasisekharan, a MIT biological engineer who spoke with the outlet.
The more contagious subvariant is raging across the U.S., but Dr. Anthony Fauci, an immunologist and director of the National Institute of Allergy and Infectious Diseases who served on former President Trump’s White House Coronavirus Task Force and is now President Biden’s chief medical adviser on COVID-19, doesn’t expect a huge surge in cases.
“The bottom line is we’ll likely see an uptick in cases, as we’ve seen in the European countries, particularly the U.K.,” Fauci said last week on ABC. “Hopefully we won’t see a surge — I don’t think we will.”
Several studies have found that BA.2 is even more transmissible than an earlier variant, BA.1, but still most scientists are not concerned.
“In early 2022, BA.2 was growing more common in a number of countries,” The New York Times recently reported. “By February, it had become dominant worldwide, driving down the once-dominant BA.1. In the United States, the Centers for Disease Control and Prevention estimated that BA.2 jumped to 11% in early March from 1% in early February. It could soon become dominant in this country as well.”
“But that does not mean that Americans are riding a new BA.2 wave that is infecting a lot of new people. As BA.2 became more common in the United States, the total number of new cases fell by about 95%. Worldwide, the number of daily new cases had fallen to half of what they were at their peak in late January,” The Times reported.
Others have echoed that sentiment.
“Cases of this particular omicron subvariant, one of a few, keep popping up and have roughly doubled the past few weeks in the U.S., according to Centers for Disease Control and Prevention data estimates,” the Miami Herald reported last Wednesday. “It now makes up 11.6% of overall virus cases as of March 5 since it began doubling as of Feb. 5.”
“All in all, I think we’re really gonna be OK and I don’t think BA.2 is gonna be problematic like omicron,” said Dr. Thomas Russo, an infectious disease doctor and professor and chief of the Division of Infectious Diseases at the University of Buffalo, according to the Herald.
