At least one person in the UK has died with the Omicron coronavirus variant, the prime minister has said, writes BBC.

Boris Johnson said the new variant was also resulting in hospital admissions and the “best thing” people could do was get their booster jab.

Visiting a vaccination clinic in London, he said people should set aside the idea Omicron was a milder variant.

On Sunday, the PM set a new target for all adults in England to be offered a booster by the end of the month.

Speaking during a visit near Paddington, west London, Mr Johnson said: “Sadly yes, Omicron is producing hospitalisations and sadly at least one patient has been confirmed to have died with Omicron.

So I think the idea that this is somehow a milder version of the virus, I think that"s something we need to set on one side and just recognise the sheer pace at which it accelerates through the population”.
