LONDON — U.K. leader Boris Johnson will speak with his top medical advisors on Monday before deciding whether to impose any new Covid-19 restrictions for England this week.

Scotland, Wales, Northern Ireland and Northern Ireland have all implemented new restrictions to prevent the spread of the Omicron variant. These curbs largely focus on indoor mixing. England is avoiding increasing mask wear and staying at home orders.

Johnson will likely digest data Monday that includes hospitalizations, ICU and case rate figures as well as deaths. Official figures were halted for the Christmas holidays, which meant that they have not been updated. However, the U.K. posted a record number of 122186 infections in 24 hours on Friday.

Johnson stated that he will not hesitate to take action and introduce new restrictions after Christmas, however research suggests that Johnson may hold firm to his promise. It will be crucial to know the duration of hospital stays as well as how many hospitalizations are caused by infections. 

The prime minister’s new restrictions would likely not be popular in the Conservative Party. Many legislators have protested against it. Many are dissatisfied with the current Covid restrictions, as well as the recent gaffes. Johnson’s rating has also been affected by national voter surveys.

The House of Commons would have to vote on new measures, and legislators will need to be returned from Christmas vacations. Johnson might instead urge caution for English citizens in advance of New Year’s Eve festivities than imposing formal restrictions.

A U.K. government study published ThursdayAccording to the study, people with the omicron Covid strain are less likely to need hospital admissions than those who have the delta variant.

U.K. Health Security Agency stated that individuals with Omicron were between 31%-45% less likely than people with Delta to visit emergency departments and 50-70% less likely need to be admitted to hospital.

Due to the low number of Omicron cases in hospitals, this analysis is “preliminary” and “highly uncertain.” but it does tally with similar findings from scientists in South AfricaResearch teams from Imperial College London, University of Edinburgh.

Although the daily death rate is low, initial research indicates that there may not be as many infections as the other Covid strains. However, experts warn that increasing numbers of infections can lead to more deaths and an overloaded health system.

According to Johns Hopkins University data, the U.K. reported almost 12 million cases of infection and 148 324 deaths since early 2020.
