30,000 Cases Detected of AY.4.2. COVID Variant That Could Spread Faster Than Original Delta
More than 30,000 cases of the AY.4.2 COVID variant have been detected worldwide, according to tracking data.
AY.4.2 is an offshoot of the Delta variant AY.4, meaning it is a variant of a variant of Delta.
It is marked by two mutations called Y145H and A222V that affect AY.4.2's spike protein, which is what the virus uses to enter human cells.
