UK Health Security Agency boss Jenny Harries has warned the UK is facing "staggering" numbers of infections in the next few days from the Omicron variant.
She told MPs the NHS was in "serious peril" from the new strain.
As the Omicron variant of coronavirus continues to spread, new restrictions have already been brought in across different parts of the UK.
The Government yesterday voted to back the introduction of Plan B regulations, which include the use of covid passports, mask wearing in most indoor places, and working from home where possible.
Nicola Sturgeon has urged Scots to limit their socialising to a maximum of three households in a bid to save Christmas.
The First Minister made the plea for the period before and immediately after Christmas - but the curb will not be put into law.
She did not propose limits on the size of household gatherings for Christmas Eve, December 25 or Boxing Day.
She told MSPs: “I am not asking anyone to ‘cancel’ Christmas - but in the run up to and in the immediate aftermath of Christmas, I am asking everyone to reduce as far as possible, and to a minimum, the contacts we have with people in other households.
“We are not banning or restricting household mixing in law as before. We understand the negative impact this has on mental health and well-being.
“But we are asking everyone - and we will issue strong guidance to this effect - to cut down as far as possible the number of people outside our own households that we are interacting with just now."
In Wales, ministers have said new rules are likely within the coming weeks.
First Minister Mark Drakeford has warned of new restrictions and said there may be a "need to take more steps to keep Wales safe".
Mark Drakeford is expected to confirm if changes are needed to the coronavirus regulations this Friday (December 17).
This could mean household bubbles and/or a return to the rule of six meeting indoors in pubs or restaurants, though nothing has been announced yet.
In Northern Ireland, the enforcement of domestic Covid-19 vaccination certificates began on Monday
