United Kingdom – Health officials are advising the public on how to manage symptoms and prevent spread as two new COVID-19 variants are fueling a rise in cases across the UK this autumn.

The variants, officially designated NB.1.8.1 and XFG but nicknamed 'Nimbus' and 'Stratus' respectively, now account for almost 90 per cent of all recorded COVID cases in the United Kingdom.
According to data released last month by the UK Health Security Agency (UKHSA), the 'Stratus' variant (XFG) and its sub-lineages were responsible for 77 per cent of cases. The 'Nimbus' variant (NB.1.8.1) made up another 11 per cent, cementing their dominance as the country heads into the colder months.
While the number of infections is increasing, the UKHSA has moved to reassure the public. In a recent blog post, the agency stated, "Current data does not indicate that these variants lead to more severe illness than other variants in circulation".
The agency emphasised that viral mutations are normal and that vaccination remains the key defence. "The most important thing is for those eligible to get their vaccination when it is due", the statement concluded.
Symptoms to Watch For
As the virus has evolved, so have its most common symptoms. While the classic signs of a fever, continuous cough, and loss of taste or smell can still occur, recent strains are more commonly associated with cold-like symptoms.
However, experts have noted distinct symptoms linked to the new dominant variants. The 'Stratus' variant is often associated with a hoarse or raspy voice. Meanwhile, the 'Nimbus' variant has been linked to a severe sore throat, described by some as a, "razor blade sensation".
The full list of possible symptoms provided by the UKHSA now includes:
Official Advice and Rising Numbers
The latest figures confirm a clear upward trend in infections. The UKHSA reported a rise in COVID positivity from 7.6 per cent to 8.4 per cent in a week. Hospitalisations have also increased from 2.00 to 2.73 per 100,000 people. In the week ending September 17, England recorded 1,995 positive cases, a 14.3 per cent increase from the previous week.
In response, the UKHSA has urged anyone with symptoms of a respiratory infection and a high temperature to, "avoid contact with vulnerable people and stay at home if possible".
For those who have symptoms but cannot stay at home, the agency recommends the following measures:
Dr Jamie Lopez Bernal, Consultant Epidemiologist at UKHSA, stressed the importance of proactive measures. "Flu and COVID-19 levels are starting to slowly increase", he said. "While this is to be expected at this time of year, now is the time for people to come forward for their winter vaccines if they’re eligible... Vaccination offers the best protection".
