More bad news out of the UK.
The Biological Warfare unit at Porton Down, have just confirmed there is a far more infectious strain of Covid-19 on the loose in the UK.
The variant - called ‘VUI – 202012/01’ - carries a set of mutations including an N501Y mutation to part of the genetic sequence which forms the spike protein - little grippy rods which attach to human cells. Any change in shape of the spike protein could make it more difficult for the immune system to spot. The virus uses the spike protein to bind to the human ACE2 receptor.
The UK government formally informed the WHO of this development last night, after the cabinet met in emergency session. They will meet in emergency session again today.
This new strain emerged recently in my home county of Kent and has been devastating. It is now starting to rip through London and the home counties. Those are the ones that surround London, but has now spread as far as East Anglia which formerly has had a low incidence.
It ability to spread the R factor is not yet entirely known. However there are fears it might be has high as three or four and have an ability to spread 3 or more times faster than other strains.
It is thought and hoped that the vaccines will be as effective against this strain, but it is still not known. The new strain appears to have the same pathogenicity, but is is significantly more contagious.
Under consideration is a total shut down of public transport and even closing roads especially restricting all transport in and out of London.
This is a breaking story, so stay tuned.
