Two newly identified Covid variants, XFG (nicknamed Stratus) and NB.1.8.1 (Nimbus), have become the most common strains circulating in the UK, health officials have confirmed.
Experts say the variants do not appear to cause more severe illness than earlier types, but recent genetic changes could make infections easier to contract.
Symptoms and Precautions
Some reports suggest distinctive signs of the new variants may include a hoarse voice or a sharp “razor blade” sore throat. However, Covid continues to present with a wide range of symptoms such as headache, cough, a blocked or runny nose, and fatigue — often resembling cold or flu.
People who suspect they have Covid are advised to avoid close contact with vulnerable individuals and, where possible, stay at home. If going out is unavoidable, officials recommend wearing a face covering, washing hands frequently, and disposing of tissues properly. For sore throats, the NHS advises fluids and simple remedies such as honey.
Rising Cases and Hospital Admissions
The Royal College of GPs reports that Covid cases are rising across the UK, especially among young children and the elderly. Hospital admissions linked to the virus are also increasing.
Those aged 75 and above remain eligible for free NHS Covid vaccinations, which the UK Health Security Agency (UKHSA) says provide good protection against the new strains. The agency is also urging people to get vaccinated against flu and respiratory syncytial virus (RSV) ahead of winter.
Health Officials Urge Vaccination
“It’s normal for viruses to mutate and change,” the UKHSA said in a statement. “The most important thing is for those eligible to get their vaccination when it is due.”
Dr Alex Allen, consultant epidemiologist at UKHSA, added: “Based on the available information so far, there is no evidence to suggest that the variants cause more severe disease or that the vaccines in current use will be less effective against them.”
Reinfections and Access to Vaccines
Reinfections remain possible, even shortly after recovery or vaccination. These are generally mild but can still cause discomfort and risk of transmission. Free Covid tests are no longer widely available, though they can be purchased at pharmacies. Vaccines are also available at some high street chemists and private clinics, with prices around £99 per dose.
