COVID variant BA.2.86 triples in new CDC estimates, now 8.8% of cases

Nearly 1 in 10 new COVID-19 cases in the U.S. are from the BA.2.86 variant, the Centers for Disease Control and Prevention estimated Monday, nearly triple what the agency estimated the highly mutated variant's prevalence was two weeks ago. 

Among the handful of regions with enough specimens reported from testing laboratories, BA.2.86's prevalence is largest in the Northeast: 13.1% of cases in the New York and New Jersey region are blamed on the strain.

Monday's figures mark the first time BA.2.86's prevalence has surged enough to be listed as a standalone variant on the CDC's estimates. Scientists first warned of the highly mutated strain's discovery over the summer.
