BA.2.12.1 is most infectious. BA.2.2 is most deadly. BA.2.23 looks ominous.
I know this from what is going on in the USA and Hong Kong respectively. BA.2.12.1 is overtaking all other variants atm in the USA. BA.2.2 has a higher CFR than other BA.2.* variants. Here is the genetic structure of their Spike protein some other BA.2 relatives. Once again I point out that BA.2 is…

Australia thinks herd immunity is possible. It is not.
When Australia started to mandate the vaccine, it must have thought herd immunity was possible but it was not, and that was with the delta variant in August/ September/October 2021. I have calculated that the R naught value of delta variant is about 12.5. Here is a graph I circulated lat year. Th R naught…

Some of the Omicron Subvariants BA.2.* seems to be more deadly than BA.2
The Case fatality rate (CFR)= deaths/cases has risen in both Denmark and the UK, and the only think I can put it down are the new subvariant BA.2.9 in Denmark and UK, and possibly also BA.2.3, and BA.2.23 in the UK. In January the CFR in Denmark dropped to 0,05% but is now at 0.7%…

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…

Was Denmark too hasty to declare that the coronavirus was just a flu and life was now normal again?
When Denmark’s Case Fatality Rate (CFR) dropped to 0.04% (7-day-runng average) in January 2022, the government of Denmark declared the pandemic was over. With a CFR so low, noting that the CFR for influenza is about 0.1 to 0.15%, that made reasonable sense. In early February most restrictions were subsequently lifted. It was said that…
