The BA.2 subvariants > BA.1 subvariants in the UK. Deaths Rising.

Just a quick update on what the variants are doing in the UK. It seems the BA.2 subvariants and all growing while the BA.1 subvariants are being replaced.

Variants in the UK as at 16 April 2022

BA.2, BA.2.3, BA2.9, BA.2.10, and BA.2.12 are all growing in prevalence with BA.2.9 probably growing the fastest and BA.2 the slowest. All the BA.1 subvariants are reducing in prevalence.

Yeah, I know. Why is BA.2 called Omicron, so different.

You can clearly see that the Case Fatality Rate (CFR) = deaths/ cases is slowly rising again after a low of 0.1% on 29 December 2022. Some of this rise may be due to less people being tested, but there has been a sharpish rise in April. Deaths are currently at 200 per day and rising. Some of the increase in deaths may also be due to the waning of vaccines, even though the vaccines are not very effective against Omicron. At this stage of the game, only the very old and their carers should be vaccinated.

There is no point in vaccinating children as herd immunity is not possible, and at the moment there are more vaccine related deaths in Australia than due to covid19.

One response to “The BA.2 subvariants > BA.1 subvariants in the UK. Deaths Rising.”

  1. Important Note:

    Omicron BA.2 lacks the genetic deletion on the spike protein which produces S-gene target failure (SGTF) in some polymerase chain reaction (PCR) tests, which has been used as a proxy for Omicron cases previously.
