The current trend of Covid-19 is gradually slowing in the US, but the emergence of a new Covid variant, known as XEC, has raised concerns among health authorities with the approaching colder weather. XEC is a recombinant strain resulting from the fusion of two closely related variants, KS.1.1 and KP.3.3, both derived from the JN.1 strain. This new variant is expected to spread more rapidly due to the numerous additional mutations it possesses, suggesting that Covid-19 is far from fading as new variants continue to surface. Here are six key points to note about the XEC variant:
1. Increased Infectiousness: Experts indicate that the XEC variant is more infectious than previous strains due to its multiple mutations. Adhering to social distancing and proper hygiene practices is crucial in preventing infections.
2. Global Spread: While originating in Germany, the XEC variant is rapidly spreading in countries such as the US, UK, China, and has been identified in 27 countries including Poland, Norway, Luxembourg, Ukraine, and Portugal. There are currently 23 confirmed cases in the US, with three in California.
3. Mild Symptoms: Symptoms attributed to the XEC variant are similar and mild, in line with the Omicron strain. Common symptoms include fever, cough, sore throat, runny nose, loss of taste or smell, breathing difficulties, muscle pain, headache, nausea, and diarrhea.
4. Vaccine Efficacy: The current Covid-19 vaccine is based on the KP.2 strain, though the virus is evolving at a faster rate than vaccine development. While the effectiveness of the latest vaccine against XEC remains uncertain, it is expected to offer some protection against severe illness and hospitalization.
5. Potential Dominance in Winter: Experts suggest that the XEC variant could become predominant during the winter months, emphasizing the need for continued vigilance and adherence to preventive measures."According to Eric Topol, the director of the Scripps Research Translational Institute in La Jolla, the variant that is most likely to become predominant in the near future is X. Experts predict that this variant will spread more quickly in the coming months.
Regarding the recombinantXEC, 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 that are contributing to the increasing number of cases globally, while KP.3.3 is a type of FLuQE variant known for its spike protein mutation that enhances binding to human cells.
To prevent Covid infection, it is essential to adhere to basic safety measures such as avoiding large gatherings, maintaining social distancing, frequent handwashing, and wearing masks in crowded places. Additionally, boosting immunity naturally through a diet rich in fruits, vegetables, nuts, seeds, and protein is crucial.
In Eastern Ukraine, Russian shelling has resulted in the deaths of seven individuals, with both countries intercepting multiple missiles and drones."
