The current surge of Covid-19 in the US is beginning to slow down, but concerns have arisen with the emergence of a new variant, XEC, as colder weather sets in. XEC is a recombinant strain formed from two closely related variants, KS.1.1 and KP.3.3, both descendants of the JN.1 strain. With numerous additional mutations, XEC is anticipated to spread more effectively than previous strains, indicating that Covid-19 is far from fading away with the continuous emergence of new variants.

Here are 6 key points about the new Covid variant XEC:

1. Increased Infectiousness: Experts suggest that XEC is more infectious than previous strains due to its multiple mutations. It is essential to adhere to social distancing and proper hygiene practices to reduce the risk of infection.

2. Global Spread: Although originating in Germany, the XEC variant is rapidly spreading across countries like the US, UK, China, and others, having been identified in a total of 27 countries, including Poland, Norway, Luxembourg, Ukraine, and Portugal. In the US, there are currently 23 reported cases, including three in California.

3. Mild Symptoms: XEC exhibits similar mild symptoms to the Omicron variant, such as fever, cough, sore throat, loss of taste or smell, and others.

4. Vaccine Efficacy: The latest Covid-19 vaccine is based on the KP.2 strain, but the virus is evolving at a faster rate than vaccine updates. While the effectiveness of the current vaccine against XEC remains uncertain, it is believed to offer protection against severe illness and hospitalization for vulnerable populations.

5. Potential Dominance in Winter: Experts warn that XEC could become dominant during the winter months."The variant that is expected to gain traction next is likely to be the most prevalent," stated Eric Topol, director of the Scripps Research Translational Institute in La Jolla. Experts predict that this variant will become more dominant and spread rapidly in the coming months.

Further information on the recombinantXEC variant reveals that it is a combination of KS.1.1 and KP.3.3, both of which are descendants of the JN.1 strain. KS.1.1 belongs to the FLiRT variants responsible for the increase in cases in various countries, while KP.3.3 is a type of FLuQE variant with a spike protein mutation that enhances its binding to human cells.

To prevent Covid infection, it is crucial to adhere to basic preventive measures: avoid crowds, maintain physical distance, wash hands frequently, wear masks in crowded settings, and enhance immunity through a balanced diet rich in fruits, vegetables, nuts, seeds, and protein.

In Eastern Ukraine, seven individuals lost their lives due to Russian shelling, with both countries intercepting multiple missiles and drones.
