Because this virus is mutating all the time, more especially in areas where it is out of control and travellers are coming from the UK which has the highest rate of infection and deaths in the world. Not all are isolating, not all wear masks, not all socially distance.

Our system is not foolproof.

 

 

It's not inevitable. However it remains a risk. It is a real possibility.

The probability of another infection is proportional to the level of infection in the UK and the number of people who cross the border. 

The measures we have in place significantly reduce the probability but unless there is full quarantine, there remains a small risk.

so the south african variant has sprung up for no apparent reason without foreign travel,   will it occur to anyone that viruses can mutate on any continent and what is putting the willies up the powers that be in the Uk probably mutated in the UK to be similar or identical to was first identified in SA ?

Anywhere it's rampant will give a perfect place for it to start picking up new mutations. It has to compete with other strains of the virus and people who've already had it. The SA variant is scary because it has come to fruition where many people have already had it, there's a pressure on it to be resistant to antibodies.

I really don't like this personification of a virus we see all the time.  "It has to compete", "Pressure on it to be resistant" etc.

It's just a strand of RNA carried in a protein envelope.  It mutates all the time because RNA replication is imperfect. It's simply natural selection (as Darwin explained) in action such that if a random mutation means the virus is more transmissable, or less attractive to a person's antibodies it's more likely to spread to the next person such that over time that mutation becomes predominant.  Until there's another one that's even more transmissable/resistant.

It's a touch anthropomorphic, granted, but not strictly inaccurate. The same accusation could be levied at "survival of the fittest", but if it was good enough for Darwin it's probably good enough for the average lay person too.

California now has its own strain too apparently, just recently identified. Let's hope it favours orange.
