The World Health Organization has issued a stark warning as new COVID-19 variants, collectively known as 'FLiRT', begin to spread rapidly across the United Kingdom. Health experts are closely monitoring the situation as these new mutations demonstrate concerning characteristics.
What Are the FLiRT Variants?
The term 'FLiRT' refers to a family of Omicron subvariants, primarily KP.2 and KP.1.1, which have developed specific mutations that make them more adept at evading existing immunity. These variants have shown increased transmissibility compared to previous strains, raising concerns among public health officials.
Current UK Situation
According to the latest data from the UK Health Security Agency, the FLiRT variants are gaining significant traction across Britain. While hospitalisations haven't seen a dramatic spike yet, the rate of community transmission is causing alarm among epidemiologists.
Recognising the Symptoms
The symptoms associated with FLiRT variants remain similar to recent COVID strains but with some notable patterns:
- Runny nose - More prevalent than in previous variants
- Sore throat - Often the first noticeable symptom
- Fatigue - Ranging from mild to severe exhaustion
- Headache - Particularly in the early stages
- Muscle aches - Similar to flu-like symptoms
- Changes to smell and taste - Less common than with earlier variants
Expert Recommendations
Health authorities emphasise that existing vaccines still provide substantial protection against severe illness, though they may be less effective at preventing infection from these new variants. Vulnerable populations, including the elderly and immunocompromised, are advised to remain vigilant and consider additional precautions in crowded settings.
Professor Susan Hopkins, Chief Medical Advisor at UKHSA, stated: 'While we're not returning to lockdown measures, we strongly recommend that individuals experiencing symptoms take sensible precautions to protect others, particularly in healthcare settings and when visiting vulnerable relatives.'
Looking Ahead
Vaccine manufacturers are already developing updated boosters targeting the FLiRT variants, with rollout expected in the coming months. In the meantime, health officials stress the importance of basic hygiene measures and staying home when unwell to limit the spread.
