While confirmed infections across the US have fallen sharply following a surge fuelled by the emergence of the Omicron variant, rising cases across parts of Europe and China have prompted public health officials to stress caution, as public health measures in most cities and states are relaxed.
The BA.2 subvariant, also known as “stealth Omicron”, accounts for nearly 35 per cent of confirmed infections in the US as of 21 March, according to the US Centers for Disease Control and Prevention.
Roughly 65 per cent of Americans, or more than 217 million people, are considered fully vaccinated. Nearly 97 million people from that group have received at least one “booster” dose. Roughly 23 per cent of the US has not received any vaccine doses.
