The variant, first detected in India in August, has gained additional mutations which make it better at evading immunity and therefore "more infectious", Prof Francois Balloux of the UCL Genetics Institute has said.
He added: "It is widely anticipated to go up in frequency globally, and may cause a sizeable fraction of cases globally in the near future.However, Prof Jonathan Ball a virologist at the University of Nottingham said there was "no evidence it's more dangerous" than current strains."Our immune system is used to adapting to viruses," he explained.
"It’s significant because it’s spreading so rapidly, we are seeing a whole slew at the moment of different Omicron variants, indeed that’s what’s causing the spread of Covid in this country. "This particular variant is unusual in that it’s spreading so rapidly - and in fact towards the end of December the number of cases with this particular variant in the US more than doubled in a week and that’s why we’re very concerned," he said.No official data has come out regarding infection signs of the new variant, but as an off-shoot of Omicron, many of its early symptoms should be similar to previous versions of the strain.
