How worried should we be about new coronavirus mutations? | TheHill - The Hill

But by the beginning of spring and summer the delta variant became the dominant version of the coronavirus in the U.S.

Currently, the delta variant remains the dominant version but there may be other mutations and subsets of the delta variant on the rise.

In recent months, a mutated version of the delta variant has been spreading slowly in the U.K.

called the delta plus variant, also known as AY.4.2.

The substrain does not seem to be spreading as quickly as the original delta variant.

Experts tend to think that the next big variant will be derived from the delta variant.

“It is very likely that the next variant will be a daughter of delta, and it may emerge anywhere,” says Vaughn S.

Recently, the UK Health Security Agency (UKHSA) has put the delta plus in the "variant under investigation" category, according to the BBC.

Public health officials there are concerned that it may spread more easily than the original delta variant, but currently do not think it causes more severe illness.
