A newly emerging COVID-19 variant, scientifically named NB.1.8.1, but more commonly referred to as “Nimbus,” is making headlines for a particularly painful symptom   what many are calling a “razor blade throat.” This unsettling nickname reflects the intense sore throat some individuals experience after infection, making it feel like swallowing sharp objects.

Where is the Variant Being Reported?

Health experts in the United Kingdom, India, and other countries have linked this symptom to the rising cases of the Nimbus variant. According to a World Health Organization (WHO) report from May 28, a recent increase in COVID-19 cases has primarily occurred in the eastern Mediterranean, Southeast Asia, and western Pacific regions. In mid-May, the variant accounted for nearly 11% of globally sequenced samples.

Airport screenings in the United States have also detected the variant in travelers arriving from these areas to California, Washington state, Virginia, and New York.

Is There a Reason to Worry?

So far, no. Despite the uncomfortable sore throat it may cause, there’s no evidence that the Nimbus variant leads to more severe illness than other strains of COVID-19. The WHO has classified it as a “variant under monitoring” and currently assesses the global public health risk as low.

What Are the Symptoms?

Along with the severe sore throat, typical COVID-19 symptoms still apply, including:

• Fever
  
  

• Chills
  
  

• Cough
  
  

• Shortness of breath
  
  

• Loss of taste or smell
  
  

Are Vaccines Still Effective?

Yes. Current vaccines are expected to remain effective against the Nimbus variant. However, vaccine guidance has stirred debate recently. In May, Health Secretary Robert F. Kennedy Jr. announced that COVID-19 shots are no longer recommended for healthy children and pregnant women   a move that has faced scrutiny from several public health professionals.

The Bottom Line

While the “razor blade throat” symptom is certainly unpleasant, experts emphasize that there’s no major cause for concern with the Nimbus variant as of now. Monitoring continues, and people are advised to follow regular COVID-19 precautions, stay informed, and seek medical advice if they experience unusual or severe symptoms.
