The New ‘American Covid’ Wave in England Is Raising an Old Question
For a virus that once ruled daily life, COVID-19 has become easy to forget. Now England is seeing another rise, and people are looking again.

The latest concern centres on XFG, a SARS-CoV-2 variant also known as Stratus. Some headlines call it “American Covid”, giving the strain an attention-grabbing identity.
But XFG is not an American disease. It has been detected across different regions, and its rise in England forms part of wider global circulation.
The World Health Organisation currently lists XFG as a variant under monitoring. It was first documented in January 2025 and remains under close surveillance.
WHO data show XFG accounted for 49.2 per cent of submitted sequences globally during the week ending August 23, rising from 29 per cent.
Those figures do not mean that almost half of all infections are XFG. Only some infections are tested and genetically sequenced, leaving gaps in surveillance.
Still, the increase is difficult to ignore. XFG has gained ground while several other SARS-CoV-2 variants have either declined or remained relatively stable.
England is seeing its own increase. UKHSA recorded 1,364 COVID-19 cases during the seven days ending September 23, 303 more than the previous week.
That represented a 28.6 per cent increase. Hospital admissions also rose, with 261 recorded in the latest available seven-day period ending August 31.
The hospital figure was 34 higher than the previous week, representing a 15 per cent increase. But there is an important warning attached.
UKHSA says reporting delays have their greatest effect on the latest four weeks. Recent hospital figures can therefore increase as additional records arrive.
That means the current numbers deserve attention, but they should not be treated as the final picture of England’s COVID-19 situation.
For anyone who remembers the pandemic’s darkest period, rising admissions may sound alarming. Yet today’s situation is very different from what England faced then.
Vaccination has changed the level of protection. Previous infections have also contributed to population immunity, while doctors have gained more experience treating severe COVID-19.
XFG itself has not been shown to cause more severe disease than other variants currently circulating. WHO says available evidence does not indicate an additional public-health risk.
That is an important detail because a rising variant can easily be mistaken for a more dangerous variant when hospital numbers begin increasing.
More infections can mean more hospital patients even when the individual risk of severe disease has not increased. Numbers can rise without the virus becoming deadlier.
The people most affected are also not necessarily the people filling social media feeds with discussions about new variants and strange COVID-19 symptoms.
Older adults remain more vulnerable to severe illness. People with weakened immune systems and certain underlying conditions can also face greater risks from infection.
For them, another increase in COVID-19 transmission is more than an interesting statistic. It can mean another period of medical appointments, hospital treatment or family concern.
For younger and healthier people, XFG may instead feel like another respiratory illness. Symptoms can include sore throat, cough, tiredness, fever, headache and congestion.
That similarity creates another problem. Without testing, someone may struggle to know whether their symptoms are caused by COVID-19, influenza or another circulating respiratory infection.
The changing symptoms have also helped XFG attract attention. Reports have associated the variant with sore throats and hoarseness, although symptoms cannot identify variants reliably.
That is why surveillance remains important. Ordinary people may only notice a few sick relatives, while testing systems can reveal a much wider movement.
COVID-19 has entered a different stage of its existence. It is no longer dominating every decision, yet it continues evolving beneath everyday life.
XFG is part of that evolution. The virus has not disappeared; it has simply become less visible to people who are no longer watching every case.
England’s current rise therefore raises a familiar question in a new setting: how seriously should people take a virus they have learned to live with?
The answer may depend on who is asking. For many people, COVID-19 now means inconvenience. For vulnerable patients, it can still mean something much more serious.
There is no evidence that England is returning to the emergency of 2020. The present figures do not point to that kind of crisis.
But dismissing the rise would also miss the lesson. A virus can become familiar without becoming irrelevant, especially when new variants continue appearing.
The “American Covid” label may attract attention, but XFG is not a foreign threat arriving at England’s door. It is another stage in COVID-19’s evolution.

For now, England is watching rather than panicking. The hospital numbers deserve attention, the variant deserves monitoring, and the public deserves facts without unnecessary fear.
