Nimbus COVID variant brings intense sore throats—feels like swallowing razor blades

A new COVID-19 variant, known as 'Nimbus', is raising concerns globally with its unique symptom of causing severely painful sore throats, described by some as feeling like “razor blades.” Officially named NB.1.8.1, the variant has rapidly gained attention, especially in regions such as the eastern Mediterranean, Southeast Asia, and the western Pacific, according to Associated Press.

The World Health Organization (WHO) noted that by mid-May, the Nimbus variant accounted for nearly 11% of sequenced samples worldwide. Cases have been identified across several countries, including China, Hong Kong, India, and the United States, where it has been detected in states like California, Washington, Virginia, and New York. Increases in infection rates have also been reported in the United Kingdom, India, and several Western Pacific countries, according to The Indian Express.

The WHO classifies NB.1.8.1 under “variant under monitoring,” emphasizing that while it's widely spread, the overall public health risk remains low. Existing COVID-19 vaccines are expected to continue to provide effective defense against severe illness associated with the variant, as suggested by health authorities.

The most notable symptom of the Nimbus variant is the intense sore throat. Additional symptoms include fever, chills, cough, shortness of breath, and loss of taste or smell. However, these symptoms are not considered more severe than those caused by prior variants, making it crucial for the public to stay informed and take standard safety measures, as per guidance from experts such as SFGate.

Health experts like Dr. Peter Chin-Hong from UCSF caution that while the variant spreads efficiently due to genetic mutations, it isn't necessarily more severe. Basic practices such as masking in crowded spaces, hand hygiene, and using well-ventilated areas remain effective measures in minimizing transmission risks.

Continued vigilance and adherence to health guidelines are essential as global health organizations monitor the Nimbus variant and its impact worldwide.
