A new variant of the SARS-CoV-2 virus, named NB.1.8.1, has been associated with a rising number of Covid-19 cases in multiple countries around the world, including regions in the Western Pacific, the Americas, Southeast Asia, and Europe. The World Health Organization (WHO) has classified NB.1.8.1 as a "variant under monitoring," meaning it "may require prioritized attention."

According to leading infectious disease experts, NB.1.8.1 is part of the Omicron family and appears to be spreading rapidly, with a higher ability to evade immunity compared to previous variants. However, there is currently no evidence that it causes more severe illness.

Symptoms of NB.1.8.1 infection are similar to those of earlier Covid-19 variants and may include:

• Fever, chills

• Cough, shortness of breath

• Loss of taste or smell

• Fatigue, body aches

• Headache, sore throat

• Nasal congestion, runny nose

• Nausea, vomiting

Effective prevention measures:

• Get vaccinated, especially for older adults and individuals with underlying health conditions

• Wear a mask in crowded places

• Stay informed through official public health sources

Experts emphasize that there is no need to panic, but increased vigilance and adherence to public health measures are essential to protect yourself and others.
