If you’ve recently experienced symptoms like a sharp sore throat and high fever, you might have contracted one of the new Covid-19 variants circulating this autumn.
Since the original coronavirus outbreak five years ago, the virus has evolved into several variants. The most prevalent strains in the UK now are XFG, also called Stratus, and NB.1.8.1, known as Nimbus.
Health experts emphasize that these variants do not appear to cause more severe illness than earlier strains. However, genetic mutations may have made them more contagious and introduced subtle changes in symptoms.

Dr. Kaywaan Khan, a Harley Street GP and founder of the Hannah London Clinic, told the Mirror, “You might still have common cold-like symptoms such as coughing and a runny nose. But we’re seeing more hoarseness of voice, likely due to mild laryngitis caused by these variants.”
This hoarseness differs from previous strains. Dr. Khan added, “A sharp sore throat and loss of taste can also indicate Covid infection. While loss of taste is less common now, it remains a key symptom.”
Viruses naturally mutate over time, and when changes become significant, new variants emerge. Covid-19 symptoms now range from headache, coughing, and nasal congestion to fatigue, closely mimicking colds or flu.
If you suspect you have Covid, it’s important to stay home and minimize contact with vulnerable individuals. If you must go out, wearing a face covering and practicing good hygiene—like regular handwashing and disposing of tissues properly—can reduce transmission.
Dr. Khan advises early testing for those who are vulnerable or immunocompromised. “Antiviral treatments can be effective but only if started early. Testing enables your GP to make timely decisions about medication.”
People aged 75 and over can access free Covid vaccinations through the NHS, which remain effective against new variants, according to the UK Health Security Agency (UKHSA). The UKHSA also recommends booking flu and RSV vaccines as winter approaches, since cases for these illnesses are rising.
“It’s normal for viruses to mutate, and as we gather more data on variants, we’ll better understand their impact on immunity and how to protect ourselves and the vulnerable,” says the UKHSA. “Getting vaccinated when eligible is key to staying safe and maintaining normal life.”
