Omicron Sub-Variants BA.4 and BA.5 Account for up to 13% of COVID Variants in U.S. – CDC – Open Source Truth



US News reported:

The BA.4 and BA.5 sub-variants of Omicron are estimated to make up nearly 5% and 8% of the coronavirus variants in the United States as of June 4, the U.S. Centers for Disease Control and Prevention (CDC) said on Tuesday.

The two sublineages, which were added to the World Health Organization’s monitoring list in March and designated as variants of concern by the European Centre for Disease Prevention and Control (ECDC), were present in all U.S. regions.

Last month, South African scientists found that the sublineages of the Omicron coronavirus variant can dodge antibodies from earlier infection well enough to trigger a new wave.
