What is the AY.4.2 variant?
- Per CNBC, the AY.4.2 variant started popping up in the summer in the United Kingdom. The variant has two specific mutations that allow it to infiltrate people’s cells.
Experts last week said the variant is likely 10% more transmissible than the original delta variant. But it is not a major cause for concern.
Should you be worried?
- “New variants are generated all the time,” he said. “That’s the normal thing that this virus is going to do. It’s going to continue to mutate. While variants may garner headlines and people may write doomsday scenarios about them, most are not going to really change the trajectory of the pandemic.”
The delta variant became so dominant throughout the world. So it’s not surprising that there would be variants of the delta variant, Adalja told Insider.
- “Delta compared to alpha was around 60% more transmissible, it was doubling every week. This is going up by a percent or two a week — it’s much, much slower. So in that sense, it’s not a big disaster like delta was. It will probably gradually replace delta over the next few months. But there’s no sign it’s more vaccine resistant, (so) at the moment I wouldn’t be panicking about it.”
