Emergence of New COVID-19 Variant XEC as a Potential Dominant Strain

Scientists have identified a new variant of COVID-19, named XEC, which is predicted to potentially become the dominant strain. The variant was first detected in Germany in June and has since been reported in the United Kingdom, the United States, Denmark, and several other countries.

According to health experts, XEC is a combination of the KS.1.1 and KP.3.3 variants. Eric Topol, Director of the Scripps Research Translational Institute in California, has stated that XEC is “just getting started” and is “definitely taking charge” as the variant likely to dominate the coming weeks.

While XEC exhibits new mutations that may aid its spread during the autumn season, vaccines are still expected to offer protection against severe cases. Those particularly vulnerable to serious illness from COVID-19 are eligible for a free booster shot through the NHS, with updated vaccines available to better counter recent variants.

In Denmark and Germany, XEC accounts for nearly 20% of recent samples tested, indicating “strong growth” of the variant. In the United Kingdom, the variant represents approximately 10% of tested samples. However, reduced routine testing poses challenges in assessing the current prevalence of COVID-19.

The latest data from the UK Health Security Agency (UKHSA) indicates a 4.3% increase in COVID-19 cases, despite a reduction in deaths. Between August and September, there was a notable decrease of 20.9% in COVID-related deaths. Hospitalizations also showed a decline, falling by 6.6%.

The NHS has emphasized that most individuals recover from COVID-19 within a few weeks, though symptoms, often resembling those of a cold or flu, can persist longer for some.
