Over 2,000 people were admitted to English hospitals with COVID in 24 hours, data shows, and Sky News has reported.
The numbers are up 90% from last week and is the highest number since the beginning of February.
There were 2,082 COVID-19 hospital admissions in England on 28 December, NHS England said.
As of today, a total of 11,452 people were in hospital in England with COVID-19.
This is up 61% from last week. In London, 3,477 people were in hospital with COVID- 19 on Thursday, and the highest number since 16 February.
There is also a shortage of lateral flow tests, and with New Years Eve tomorrow, concerns are growing that mixing with others without testing could add to the spike in Omicron cases across the nation.
In a letter sent to MPs, Health Secretary Sajid Javid said people should continue to take lateral flow tests when coming into contact with vulnerable people or doing risky activities.
He added: “In light of the huge demand for LFDs seen over the last three weeks, we expect to need to constrain the system at certain points over the next two weeks to manage supply over the course of each day, with new tranches of supply released regularly throughout each day.”
