XBB is a recombinant variant
XBB is a recombinant variant, which means it was not derived from a mutation but from the crossover of 2 Omicron subvariants BA.2.75 and BA.2.10.1. Experts are saying they are not concerned about XBB but that is just guessing as there are changes in the SARS-CoV-2 virus that are not just limited to the spike-protein,…

Omicron subvariants continue to evolve but where is this going?
Omicron subvariants have been mapped out before they are even detected. See diagram in blog below. BQ.1 and BQ.1.1 are starting to get a mention now. Read this. https://www.salon.com/2022/10/04/bq1-xbb-variants-resistant/?s=07&fbclid=IwAR0JUeHrfN0P5pqY6NePV_9ejQl6DFGDPI_4md2O8naBTcJX7DPF4xkU4p0 I have also observed that BA.4 may have given in to BA.5, which got to be named a variant of concern in it’s own right, but…

Patient with coronavirus for 471 days has 3 variants that evolved within him.
That is like 15 months. Apparently the poor guy just could not shake the virus off and scientists say at least 3 different variants/strain evolved just inside him that they know of. Carrying different variants or strains simultaneously can lead to crossover and recombinant variants. This is sex for a virus, and potentially a quantum…

Is pox crossover possible? Could viruses be the origin of sex in species?
We know that monkeypox virus does not mutate much (being a DNA virus) but can it recombine or crossover with the monkeypox virus from Nigeria or Congo? And what about other orthopoxviruses in animals, or even the small pox vaccine if they still use cowpow or vaccinia. The problem will be exacerbated if animals get…

Omicron BA.1, BA.2,BA.4, BA.5, BA.12, then omicron recombinants deltacron, Omicron XA, XB, XC, XD, XE, … , XW, XX, XY, XZ, XAA, XAB, … , etc., BC.1, BC.2, BD.1, BD.1.1, etc.
Most people would have heard of “deltracron’, a recombinant variant made from the omicron and delta variants. I do not know if deltracron has survived. Most people would also have heard of the recombinant Omicron XE, which is a recombinant of Omicron BA.1 and BA.2. The status of Omicron XE is also unknown. Why are…

Omicron XE causing new surge in Covid in Malta
Yes, Omicron XE is still active. Omicron XE is a recombinant of the variants BA.1 and BA.2. BA.2 is very different to BA.1 and virologists are just starting to relabel BA.2 variants in a class of their own. The BA.2 variants should have been given a new Greek letter by the WHO. Recombinant variants are…

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…

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…
