Omicron sub-variant BA.2 makes up 11.6% of COVID variants in U.S. - CDC

According to the Centers for Disease Control and Prevention (CDC), the BA.2 sub-variant of Omicron was projected to account for 11.6 percent of the coronavirus variants circulating in the United States as of March 5, 2018.

In South Africa, scientists are seeing an increase in cases caused by BA.2, the prevalent strain, which is spreading quickly in regions of Asia and Europe.

According to preliminary statistics, the BA.2 variation seems to be more transmissible than the original BA.1 sub-variant, according to the World Health Organization (WHO) published last month. According to a report published this month by Africa’s main public health organization, BA.2 does not cause more severe illness than BA.1.

The number of daily cases in the United States has begun to fall in recent weeks after reaching record highs in January, thanks in part to the CDC’s relaxation of its COVID-19 rules for masks, which now include use in schools.

Other Omicron sub-variations, known as BA.1.1 and B.1.1.529, that have been circulating since December have now accounted for about 73.7 percent and 14.7 percent of all circulating variants, respectively. BA.1.1 is a sub-variant of Omicron that has been circulating since December.

BA.2 was estimated to account for 6.6 percent, down from the previous week’s estimate of 8 percent, of circulating variations in the United States, according to a CDC model that assesses the proportions of circulating variants in a given population.

In the past, the Centers for Disease Control and Prevention (CDC) has changed its estimates when new information became available.
