  • A new RECOMBINANT variant XBC.* has formed in the Philippines

    A new RECOMBINANT variant XBC.* has formed in the Philippines

    Recombinant variants are are not formed by mutations but when two strains/variants combine/crossover inside the same cell, which transferases part of the mRNA of one variant and that of another and combines them. This can only happen of a person is simultaneously infected with 2 variants at the same time. So far not too much…

  • XBB is a recombinant variant

    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,…

  • How monkeypox could have mutated so much. Did a human defence mechanism against viruses help generate it?

    How monkeypox could have mutated so much. Did a human defence mechanism against viruses help generate it?

    Lots of scientist have recently been suggesting that monkeypox may have been circulating in the community since 2017, but this fails to address the question as to why so many mutations have taken place, when it generally mutates on average only once a year. Monkeypox mutates less than SARS2-CoV2 because it is a DNA virus…

  • Move over for BA.12. Ten-times more infectious than BA.2

    Move over for BA.12. Ten-times more infectious than BA.2

    A new variant of the novel coronavirus, BA.12, was found in Bihar’s Patna on Thursday. According to the state’s health department, the new variant of Omicron was found in the Indira Gandhi Institute of Medical Sciences (IGIMS). There is a new kid in town and we have not dealt with waves from BA.2.9, BA.2.2, BA.2.12, BA.2.12.1,…
