New Omicron variants of concern are exploding in number. Next wave will be BA.2.75.
Some time ago I questioned why BA.2 and all subvariants like BA.2.* (* being wild card) where even listed under Omicron as they were vastly different to the BA.1.* subvariants. BA.3 was a lot like BA.1 but has since vanished because it was less contagious. Anyhow people have now separated all the BA.2 subvariants in…

Welcome to BE.1
A new variant is in NSW BE.1 that is even more infectious than BA.4 and BA.5. You can see in the graph below it is growing with respect to BA.4 and BA.5. As noted earlier (see below) the number of Omicron variants has exploded, with so many new names. I estimated some time ago that…

Number of enumerated Omicron subvariants now 119
That is where people have got to in updating the number of Omicron variants anyhow. There are more likely 300 to 400 of them, but the number of variants are going too fast to keep track of of all of them. Variants like B.2.23 and BA.2.33 had been seen in Australia and the USA but…

BA.4 and BA.5 dominate Covid cases in South Africa
BA.4 and BA.5 have almost completely dominated all the Omicron variants now (see below). Compared the rest of the world which is still going through a BA.2 variant wave (see below). Here is the United Kingdom: Here is the USA: The grey area in the bottom right corner is the rapidly growing BA.2.12.1 Here is…

Omicron now has 73 subvariants
Omicron B.1.1.529, now has 73 subvariants. These variants are being generated in the huge “virus pools” of vaccinated people as I have repeatedly noted since July 2021. The Delta variant generated 245 sublineages. The problem is that vaccines do not stop infection and transmission of the coronavirus. Currently vaccines have an efficacy of about 30-40%…

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. 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…

BA.2 is not Omicron. And what are BA.4 and BA.5?
BA.2 is very different to BA.1 and BA.3. Why is it called Omicron? Because it came from South Africa around the same time. I thought the whole purpose of using Greek letters was so we could not tell where the variant came from. Delta always reminds me of the Ganges delta plains and hence of…

The subvariants of Omicron have exploded. Australia is getting buried in new subvariants from within and from the outside. Welcome to the “New World Disorder”.
Last I looked (a couple of day ago) we had 54 subvariants of Omicron listed by GISAID. BA.1 was the one that swept the world first. BA.2 looked more ominous as its spike protein was quite different to BA.1 and BA.3, and it subvariants are the ones I have been most concerned about. Look at…
