The current surge of Covid-19 in the US has shown signs of slowing, but concerns have arisen with the emergence of a new Covid variant called XEC as the colder weather sets in. This recombinant strain, formed from closely related variants KS.1.1 and KP.3.3, both descendants of the JN.1 strain, is expected to potentially spread rapidly across the US due to its numerous mutations. Covid-19 does not appear to be diminishing as newer variants continue to arise. Here are six key points to understand about the new Covid variant XEC:
1. Increased Infectiousness: Experts note that the new XEC variant carries multiple additional mutations, making it more infectious compared to other strains. It is crucial to maintain social distancing and proper hygiene practices to reduce the risk of transmission.
2. Global Spread: Originating in Germany, the XEC variant is rapidly spreading in countries such as the US, UK, and China, with reports of detection in 27 nations, including Poland, Norway, Luxembourg, Ukraine, and Portugal. In the US, there have been 23 reported cases, including three in California.
3. Mild Symptoms: Symptoms associated with XEC are similar to those of Omicron, with manifestations such as fever, cough, sore throat, runny nose, loss of taste or smell, breathing difficulties, body aches, headaches, nausea, and diarrhea generally being mild.
4. Vaccine Efficacy: The current Covid-19 vaccine is based on the KP.2 strain of the virus. However, the rapid evolution of the virus raises doubts about how effectively vaccines can keep pace. Although the efficacy of the latest vaccine against XEC is uncertain, it should still provide protection against severe illness for vulnerable populations.
5. Winter Dominance: The XEC variant is anticipated to thrive during the winter months, potentially becoming the dominant strain."The variant considered most likely to become prevalent next is X," stated Eric Topol, director of the Scripps Research Translational Institute in La Jolla. Experts predict that this variant will become dominant in the coming months and spread more rapidly.
Further details about the variants involved in the recombinant XEC show that it is a combination of KS.1.1 and KP.3.3. Both of these variants are descendants of the JN.1 strain. KS.1.1 belongs to the FLiRT variants group, which is contributing to the rising number of cases globally. On the other hand, KP.3.3 is classified as a FLuQE variant due to a mutation that enhances its binding efficiency with human cells.
To prevent Covid infections, it is crucial to follow basic preventive measures. This includes avoiding crowds, maintaining a safe distance from others, frequent hand washing, and wearing masks in crowded areas. Additionally, boosting your immunity naturally through a diet rich in fruits, vegetables, nuts, seeds, and protein is important.
