Omicron sub-variant BA.2 accounts for about 55% of Covid variants in US, says CDC



The US national public health agency said on Tuesday that BA.2 sub-variant of Omicron was estimated to account for more than half the coronavirus variants in the country.


A resurgence of Covid-19 cases in parts of Asia and Europe has raised concerns that another wave could follow in the United States; but the country’s health experts believe it is unlikely.


Evercore ISI analyst Michael Newshel said the 7-day rolling average for Covid cases bottomed a week ago; at just under 29,000 and has stayed at about the same level.


“There could be a modest increase in cases in the short term as more states bottom; but there are still no signs of a sharp reversal to the degree seen in many countries in Europe,” Newshel said in a note.

Last week, top U.S. infectious disease official Dr Anthony Fauci said that although he does not expect a major surge; he would not be surprised to see a rise in cases owing to the increasing dominance of the BA.2 sub-variant.


The highly transmissible BA.2 sub-variant is estimated by the US Centers for Disease Control and Prevention (CDC); to make up 54.9% of the Covid-19 variants in the United States, as of March 26.


BA.2 made up 39%, revised up from 34.9%; of the variants in the country for the week ended March 19, according to CDC estimates.


Most people in the United States are now considered to be in low Covid transmission; according to new CDC guidelines introduced last month that emphasized hospital capacity over case counts.
