Face masks will be made mandatory in shops and on public transport from Tuesday, the UK health secretary said on Sunday, under fresh measures designed to contain the spread of the new Omicron coronavirus variant.
Sajid Javid said the government was “nowhere near” imposing stricter rules on homeworking and social distancing after the UK detected its first cases of the variant.
A third confirmed case has been identified in the UK, and dozens more are being treated as suspected cases, people familiar with the matter have told the Financial Times.
The latest case had no immediate travel history, the people said, adding it had been identified through genomic sequencing.
A number of cases are being investigated in London and a single potential case in Bedfordshire, according to people familiar with the process.
Javid said on Sunday morning that he was not aware of more cases being identified in the UK.
In a development that could suggest the strain was already in the UK before it was officially identified, public health leaders have been briefed that among the cases being investigated is a traveller who arrived back in the UK from South Africa on November 16.
If the person is confirmed to be infected with Omicron, it would suggest the mutation may have been circulating in the country for significantly longer than previously thought.
Under measures announced over the weekend, everyone entering the UK will be required to take a PCR test within two days of their arrival and must self-isolate until they receive a negative result. The government’s website says the new measures will be introduced from 4am on Tuesday.
Any contact of a suspected case of Omicron must also isolate for 10 days, regardless of their vaccination status.
While scientists continue to assess the new variant, the government has not yet deployed its Covid-19 plan B, which includes work from home guidance and Covid passports for mass events.
“We know now that those type of measures do carry a very heavy price, both economically, socially, in terms of non-Covid health outcomes such as the impact on mental health,” Javid told Sky News’s Trevor Phillips on Sunday show.
“If one was to make decisions like that, it would have to be done very, very carefully. We’re not there yet. We’re nowhere near that.”
Javid confirmed that masks would be made mandatory, but not in pubs and restaurants. All measures will be reviewed within three weeks.
The new UK measures were introduced as the variant continued to spread in Europe and scientists raced to assess the new level of risk.
Professor Chris Whitty, the UK’s chief medical adviser, has warned the variant may be able to evade vaccine protection, but insisted that it was likely vaccines would still help prevent severe illness and death.
Javid said he was expecting an update imminently on expanding the availability of booster vaccines for under-40s from the Joint Committee on Vaccination and Immunisation, a body of academics and clinicians who advise on vaccine policy.
Results of tests to gauge Omicron’s response to vaccines and immune systems were not expected for two to three weeks, scientists and officials said.
The people familiar with the third case said checks were under way to establish whether it was linked to travellers from the ten countries currently on the red list.
About 40 travellers appeared to show, in preliminary assays, the presence of Omicron, one of the people said. Tests are being carried out to confirm this finding through genomic sequencing. The travellers are being told to re-swab and isolate.
