Tier 4 imposed - mutant strain identified (in October!) - Christmas Lockdown! - Ports sealed, continent cut off! - Boris and Matt save the UK again!
"some experts think the episode has been overegged"
"no evidence” the new variant impacts the severity of the disease, for better or worse"
"Whatever the increase in transmission, the R rate for the new variant is still far below what it was at the start of the epidemic"
This Telegraph article has more - much more - well worth reading.
And finally - thousands of different mutations have been identified so far - the only difference identified for this one is that it might spread a bit faster (although just how much faster seems to be shrouded in considerable doubt at present). If countries are going to impose knee-jerk lock-down and travel restrictions based on the prevalence of individual strains then the stage seems set for incomprehensible rules of unimaginable complexity and ensuing gridlock in short order!
