**New COVID Variant NB.1.8.1 Spreading, Raising Concerns of Summer Wave**

A new COVID-19 variant, NB.1.8.1, is rapidly spreading across the globe, prompting experts to warn of a potential summer surge in cases. The variant, dubbed “Nimbus” by some, is a descendant of Omicron and has been identified as the cause of a resurgence in China and several other Asian countries. In the United States, the Centers for Disease Control and Prevention (CDC) reports that NB.1.8.1 already accounts for approximately one-third of new COVID-19 cases, a significant jump from just 5% a month ago.

According to CNN wellness expert Dr. Leana Wen, the World Health Organization (WHO) has classified NB.1.8.1 as a “variant under monitoring.” While data doesn’t indicate increased severity compared to previous strains, concerns remain about its potential for immune escape, meaning it may be less responsive to existing vaccines.

Symptoms of the new variant appear similar to previous strains, ranging from allergy-like symptoms to more severe flu-like symptoms. Dr. Wen emphasizes that while most will recover, some individuals, particularly the elderly and those with underlying conditions, are at higher risk of severe illness and hospitalization.

Given the uncertainty surrounding the new variant and potential changes to vaccine guidelines, Dr. Wen advises individuals to assess their risk and consult with their healthcare providers. Those 65 and older or with chronic conditions should consider getting another dose of the current vaccine now, as it likely retains some efficacy. Younger, healthy individuals may also consider vaccination before potential changes to guidelines restrict eligibility.

Dr. Wen also reiterated that standard precautions such as mask-wearing in crowded indoor settings, particularly for vulnerable individuals, can help mitigate the risk of contracting the virus.

Federal health officials are expected to make decisions soon on the formulation of the updated fall COVID-19 vaccine, likely considering the prevalence of NB.1.8.1 to ensure optimal protection.
