New COVID-19 Variant XEC Emerges
A newly discovered COVID-19 variant, XEC, has emerged as a recombinant strain of Omicron variants KS.1.1 and KP.3.3. While its symptoms are similar to other variants, experts believe it may become more contagious due to its Omicron lineage.
XEC Variant in the US
XEC has been detected in at least 25 US states, though its prevalence may be underestimated due to limited genetic testing.
Vaccine Protection and Recommendations
Current COVID-19 vaccines and booster shots provide protection against XEC. The CDC recommends that all individuals over six months of age receive an updated COVID-19 vaccine for optimal protection.
Dominant COVID-19 Strain in the US
KP.3.1.1 remains the dominant COVID-19 strain in the US, accounting for over 50% of positive infections. This variant is similar to other circulating Omicron variants and shares a common ancestor.
COVID-19 Symptoms
XEC does not appear to cause unique symptoms. Common COVID-19 symptoms include fever, cough, shortness of breath, fatigue, muscle aches, and loss of taste or smell. Seek medical attention if you experience severe symptoms such as trouble breathing, confusion, or discoloration of the skin.
