The current surge of Covid-19 in the US is showing some signs of slowing down; however, the emergence of a new variant called XEC has raised concerns among health authorities as colder weather approaches. XEC is a recombinant strain that combines elements from two closely related variants, KS.1.1 and KP.3.3, both descendants of the JN.1 strain. This new variant is expected to spread more easily due to its additional mutations. As newer variants of Covid-19 continue to arise, it is evident that the virus is not receding. Here are 6 key points to know about the XEC variant:
1. Increased Infectiousness: Experts have identified numerous additional mutations in the XEC variant, making it more infectious than previous strains. It is crucial to adhere to social distancing and proper hygiene practices to reduce the risk of infection.
2. Global Spread: Originating in Germany, the XEC variant is rapidly spreading in countries such as the US, UK, and China, with confirmed cases in 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: Symptoms associated with XEC are akin to the Omicron variant and have generally been reported as mild, including fever, cough, sore throat, runny nose, loss of taste or smell, difficulty breathing, muscle pain, headache, nausea, and diarrhea.
4. Vaccine Effectiveness: The Covid-19 vaccine has been developed based on the KP.2 strain of the virus. However, the rapid evolution of the virus raises uncertainty about the effectiveness of current vaccines against XEC. Nevertheless, vaccines can still offer protection against severe outcomes for high-risk populations.
5. Potential Dominance in Winter: There are concerns that the XEC variant could become dominant during the colder months."Eric Topol, director of the Scripps Research Translational Institute in La Jolla, believes that a particular variant is likely to gain momentum soon. Experts predict that this variant will become more dominant and spread more rapidly in the upcoming months.
Further information on the recombinantXEC variant reveals that it is a combination of the KS.1.1 and KP.3.3 strains, both of which are descendants of the JN.1 strain. KS.1.1 belongs to the FLiRT variants that are contributing to rising case numbers in various countries. On the other hand, KP.3.3 is a FLuQE variant characterized by a mutation from glutamine to glutamic acid on the spike protein, enhancing its ability to bind to human cells.
To prevent Covid infections, it is essential to adhere to basic precautions such as avoiding crowded places, maintaining a safe distance from others, frequent hand washing, and wearing masks in crowded areas. Additionally, supporting your immune system through a diet rich in fruits, vegetables, nuts, seeds, and protein is crucial.
