The UK Health Security Agency reported that American COVID hospital admissions in the UK rose 50 percent in one week as XFG spread. In London, admissions climbed by nearly 80 percent, adding pressure as people in the UK head toward winter.
That rise came alongside a jump in positive hospital Covid tests from 5.9 percent to seven percent. XFG was first detected early last year and has since spread in both the US and UK, making this a fast-moving seasonal increase rather than a flat background level.

Dr Matthew Siggins, a lecturer in immunity and infection biology at the University of Surrey, said the increase in cases was “not unexpected at this time of year” and that the rise in admissions is still classified as a baseline level. He said the weekly jump should be read against the run-up to winter, when Covid in the UK often moves more quickly through communities.
That does not mean the shift is being felt evenly. The London figure moved faster than the national one, and the NHS advice remains straightforward for anyone with symptoms: stay at home and limit contact with others if you have Covid symptoms and either a high temperature or do not feel well enough to go to work or carry out usual activities.

Dr Renée Hoenderkamp, a General Practitioner, said she is commonly seeing sore throats, headaches, runny noses and fatigue in recent Covid infections. She said the American Covid strain is “very flu-like,” which makes it easier for some people to mistake it for an ordinary winter illness and carry on until symptoms worsen.
Professor Emma Wall of Queen Mary University of London said, “Some people will be floored by an infection while others remain asymptomatic, and we don’t yet completely understand the biology behind that.” She added, “Some people have very effective T-cells that clear an infection before you know you’ve got it, while in others they can stimulate an inflammatory response to the infection that affects the whole body, which is probably part of what makes some people feel so ill.”
NHS guidance for People in the UK
The NHS says people who test positive should try to stay at home for five days after taking the test and should avoid meeting people who are more likely to get seriously ill from infections for 10 days. The NHS also says people can go back to normal activities when they feel better or do not have a high temperature, and that rest, water, paracetamol or ibuprofen, and turning the heating down can all help.
For people in the UK, the immediate next step is practical rather than political: watch for the symptoms doctors are already seeing, follow the NHS advice if a test is positive, and treat a rapid rise in admissions as a sign that the current wave is moving through hospitals as well as homes. The next weekly figures will show whether XFG keeps pushing admissions higher or levels off at the current baseline.
