Delta subvariant has made UK health officials worried

The sub-variation of the Delta, which is spreading in the UK, has worried health officials in that country. The new form of the virus seems to be highly contagious, but not very dangerous.

The “AY4.2” variant accounted for 6% of total cases in the UK last week, according to the UK Health Security Agency in its weekly bulletin, which classified it as a “variant under investigation”.

So this does not represent a “worrying variation” and is not a moment adorned with a Greek script.

“Preliminary evidence shows that it has a higher transfer rate compared to the Delta,” the British Public Health Agency said.

“Further evidence is needed to determine if this is related to a change in the behavior of the virus or to an infectious condition,” he added.

On the other hand, this variant does not result in high hospitalization and “does not appear to cause a more severe version of the disease or the currently distributed vaccines are less effective”.

So this new variant is unlikely to change the course of the epidemic. But the AY.4.2 variant demonstrates that SARS-CoV-2 still has the potential to develop into newer, more contagious mutations.
