An even more infectious version of Omicron is now dominant in England, health chiefs revealed today. BA.2 was behind 52 per cent of all Covid infections in the seven days to February 20, up from 19 per cent a fortnight ago, the UK Health Security Agency found, reports Daily Mail.
Is the BA. 2 Variant life threatening?
The sub-variant has completed its rapid rise to dominance just a month after it was first spotted in the UK.
But the scientific community has said there is no reason to panic, with the variant already in almost every case in Denmark but leading to no effect on hospitalisations or deaths.
The Government there deemed the strain such a non-threat that it has ended virtually all Covid restrictions — like England did this week.
There is so far no evidence BA.2 is more severe or better at evading vaccine-induced immunity than the original Omicron.
And Professor Paul Hunter, an infectious diseases expert at the University of East Anglia, told MailOnline it was unlikely to even cause cases — which have been falling for weeks — to pick back up.
About deltacron
Writing in today’s report, the UKHSA also revealed 32 cases of ‘Deltacron’ had now been spotted in England.
The hybrid of Omicron and Delta emerged January 7, in a person who had both variants at the same time.
It has triggered just two infections in the past week.
Dominant strain
Delta also has an S-gene, but the variant has been completely eradicated in the UK by the two much more virulent strains.
London had the highest share of BA.2 (63 per cent of Covid cases), followed by the South East (57 per cent), East of England (53 per cent), North West (51 per cent) and West Midlands (50 per cent).
The regions where it was not dominant were the East Midlands (49 per cent), Yorkshire and the Humber (43 per cent), North East (33 per cent) and South West (33 per cent).
Professor Hunter said: ‘Ultimately, we could have done without BA.2, but it will not make too much of an impact.’
He added: ‘I don’t think BA.2 is going to undermine the current drop in cases.
‘The consensus opinion of epidemiologists that I’ve listened to is that it is probably not going to be something that will undermine our position.’
Deltacron cases
A fortnight ago the UKHSA revealed it had spotted the UK’s first case of the so-called Deltacron in England.
The agency said they were keeping tabs on the hybrid, but that it was not concerning because there was no noticeable uptick in cases.
Scientists also called for calm, saying it ‘shouldn’t pose too much of a threat’ because the UK has such high levels of immunity against both Omicron and Delta strains.
Not the time to relax
Despite the rise in BA.2, Government dashboard data shows that Britain’s cases, hospitalisations and deaths are all trending downwards even as the more infectious version of Omicron became dominant.
It has given Boris Johnson the confidence to lift the final Covid restrictions, with self-isolation coming to an end yesterday for the first time in almost two years.
Free Covid tests are also set to end from the start of April, ministers have announced, in a drive to save £2billion a month.
Mr Johnson said he could lift the final Covid restrictions because of widespread immunity and the mildness of Omicron.
But he warned this was not victory over the virus, adding that it was not yet ‘going away’.
SAGE scientists have warned the mildness of Omicron may be a ‘chance event’, and say it is a ‘common misconception’ that viruses become weaker overtime.
But other scientists argue that high levels of immunity in the country mean it will not experience a Covid wave like in March 2020 again.

Highly descriptive post, I enjoyed that a lot. Will there be a part 2?
