Virus as they mutate tend to have more transmissible but less dangerous selection of subtype. It’s not only normal it is axiomatic. This is actually a good thing and in the absence of vaccines how pandemics end. Accelerated number of cases less deadly. Herd immunity more rapidly
Thank you gas_dr!
You are one of my big faves here you know. You are absolutely correct, ..again...as usual. I consider you the authority.
I understand that there is a split in the spike protein, that makes SARS-CoV-2 more transmissible than other RNA viruses. I understand it makes its own furin pathway which makes it more transmissible than SARS 1. What mechanism could account for greater transmissibility in this mutated strain?
SARS-Cov-2 has an error correction gene. However the Brazilians ran a Sanger sequence on their virus floating around over there and found a mutation which disabled the repair gene. I have been expecting this same mutation to happen in many places, and many new variants all of which will inevitably, due to natural selection, be less deadly.
Please correct me. I do not state to declare. I state whatever I do so that I may be corrected.
