COVID-19 Update: What You Need to Know About the New ‘Nimbus’ Variant and the So-Called ‘Razor Blade’ Sore Throat

A newly emerging COVID-19 variant, NB.1.8.1—nicknamed “Nimbus”, is making headlines for a particularly painful symptom: an intense sore throat described by some as feeling like “razor blades.” While this may sound alarming, here’s what travelers and patients need to know.

Where Is the Nimbus Variant Spreading?

According to the World Health Organization (WHO), recent rises in COVID-19 cases have been observed primarily in:

• Eastern Mediterranean
• Southeast Asia
• Western Pacific regions

U.S. airport screening has also detected the variant in travelers arriving in California,
Washington, Virginia, and New York, reinforcing the need for vigilance among international
Travelers.

How Serious Is It?

So far, the Nimbus variant does not appear to cause more severe illness than previous strains.
While some regions are seeing an uptick in hospitalizations, there is no clear evidence that this
variant leads to more serious outcomes.

What Are the Symptoms?

In addition to the unusually sharp sore throat, symptoms remain largely consistent with
previous variants:

• Fever or chills
• Cough
• Shortness of breath
• Fatigue
• Loss of taste or smell

Are Vaccines Still Effective?

Yes. The WHO classifies Nimbus as a “variant under monitoring,” with a low global public health risk. Current COVID-19 vaccines are expected to remain effective, especially in preventing serious illness and hospitalization.
