Covid Wave number 7 is upon us in Australia
Sigma (BA.2.75.*) is in Australia and has been for over a month but is now starting to grow in prevalence compared to Pi (BA.5.*). Don’t forget to get that fifth jab in. Klaus Schwab recommends it. The nomenclature is a bit confusing. Greek letters should have been assigned to BA.2.* (Rho), BA.5.* (Pi) and now…

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…

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…
