How does coronavirus mutate? Why does the UK have so many variants? | Science | News


Professor Martin Michaelis and Dr Mark Wass from the University of Kent have provided an explanation as to why viruses have mutated so much in the UK.

They explained to Express.co.uk: “Although viruses like SARS-CoV-2 have high mutation rates, they may not change their features until there is a substantial selection pressure that favours new variants.

“One such selection pressure is caused by an increasing level of immunity in a population.

“Hence, it is no surprise that novel variants are found in places with high levels of Covid-19 spread or Covid-19 vaccination programmes, such as the UK, Brazil and South Africa.
