Interesting Twitter discussion of the announced new strain, that reminds us that there are always new variants appearing and becoming dominant if successful.The screenshot shows the new variant (red) increasing, but remember that there are other colours (variants) not being picked up by the PCR test (but that can be picked up by genome sequencing).The infectiousness of the different strains has always been high and as new variations evolve, usually become more virulent if they are dominant, so it is not out of the normal where virii are concerned.Our approaches should stay the same -- distancing masks space and air, and fast safe vaccine roll-out where possible

A scientific expert said it is likely that the new mutated coronavirus in the UK will become the dominant global strain of Covid-19.
Calum Semple, professor of outbreak medicine at the University of Liverpool and a member of the Scientific Advisory Group for Emergencies (Sage), told Sky News:
"I suspect it will, or strains like it will (become dominant).Because the virus has the evolutionary advantage in transmitting more quickly, it will out-compete all the other strains, and so it will naturally do that.As immunity comes into the community more widely, then youíll start to see more pressure on the virus and youíre more likely to see other escapes of other variations.This is not a surprise, we deal with this with influenza year-on-year.The flu vaccine typically contains three or four flavours of the influenza virus and we simply pick on a best-guess basis each season and then people that make the vaccines scale up in a timely manner."
the second attachment below shows where the new, potentially more infectious variant of Covid-19 has been detected so far in the UK -- most prevalent in the SE but has started to spread all over the country -- from a tweet from Niko Kommenda who does the graphics for the Guardianremember like most dominant strains it spreads like wildfire given the chance -- so distance , wash hands , air, space, masks, and vaccine roll-out is still our way out of this, where services won't be over-run, and those fit young or immune can get about the new normal..
