Omicron subvariant BA.2 has become dominant COVID strain in US — but cases not spiking

COVID-19 case numbers have remained stable in the US, even as the highly contagious BA.2 subvariant has spread to become the dominant form of the virus.

Centers for Disease Control and Prevention Director Dr. Rochelle Walensky said the new subvariant now accounts for around 72% of cases nationally, though figures show it has not driven a new surge like it has in European countries.

“Looking across the country, we see that 95% of counties are reporting low COVID-19 community levels, which represent over 97% of the US population,” Walensky said at a White House press briefing Tuesday.
