A new Covid-19 variant, known as XEC, is gaining traction across Europe and may soon become the dominant strain. First identified in Germany in June, XEC has since been detected in countries including the UK, US, Denmark, and several others. This variant, a hybrid of omicron subvariants KS.1.1 and KP.3.3, has been found in 500 samples across 27 countries, including Poland, Norway, and Portugal.
Experts suggest that XEC, with its new mutations, could spread more easily this autumn. Despite its increased transmissibility, vaccines are expected to remain effective in preventing severe cases. Professor Francois Balloux of University College London noted that while XEC has a slight transmission advantage, it is anticipated to become the dominant subvariant over the winter.
Eric Topol from the Scripps Research Translational Institute emphasized that XEC is in the early stages of spreading, with significant waves potentially occurring in the coming months. The variant is predicted to take several weeks to months before significantly impacting infection rates.
The symptoms associated with the XEC variant are similar to those of previous Covid-19 variants, including fever, sore throat, cough, loss of smell, and body aches. Health officials recommend continuing to stay updated with vaccines and booster shots for adequate protection. The US Centres for Disease Control and Prevention (CDC) has advised maintaining good hygiene and ensuring clean air.
Researchers are calling for closer monitoring of the XEC variant to better understand its effects and spread.
