Rise of new Covid FLiRT strain sparks stay at home warning

A new Covid FLiRT variant is causing concern worldwide, with the potential for a summer spike in cases. This latest strain, which evolved from the once-dominant JN.1 variant linked to Omicron, has seen the KP. 2 strain become the most prevalent in the US.

That represents 28.2% of all cases up to 11 May. Additionally, another FLiRT variant, KP. 1.1, has been identified, currently making up 7.1% of infections, according to reports.

Epidemiology expert Jennifer Horney from the University of Delaware cautioned: "While our idea of what a wave of COVID-19 infections looks like has changed over the course of the pandemic, it is likely that these new strains will cause increases in the number of cases in the US over the next few months."

Speaking to CNBC, Ms Horney added, "Many will be mild, based on our existing immunity and not the changes to the circulating strain," reports Birmingham Live. Despite this, the World Health Organisation noted earlier this month that while case numbers remain low across reporting countries, some are experiencing "slight increases in detections from very low levels."

The UK's Health Security Agency is keeping a close eye on the emerging data concerning these variants, both domestically and internationally, evaluating their impact and how vaccines hold up against them. As of now, there has been no alteration to the public health guidance, the agency confirmed in its latest briefing.

UKHSA has issued a warning to those experiencing symptoms of a respiratory infection, such as COVID-19, advising them to avoid contact with vulnerable individuals. They urge such people to stay at home if they are feeling unwell or have a high temperature.

In addition, the health agency emphasised: "Vaccines remain our best defence against severe disease and hospitalisation from flu and COVID-19. That's why we're asking over-75s, those who have a weakened immune system, and anyone living in a care home for older adults, to come forward for their spring vaccination."
