That’s up from 13.7% of new cases for the week ending March 5, 7.1% for the week ending Feb. 26, and 4.1% for the week ending Feb. 19.
BA.2 is dominating the number of infections in many nations, especially in European nations that are reporting COVID surges even as governments lift many COVID safety restrictions. The United Kingdom recently said BA.2 makes up the majority of cases there. China, which had successfully tamped down COVID surges, is also grappling with a spike in BA.2 cases.
