A new COVID-19 variant called NB.1.8.1, or “Nimbus,” has been linked to a rise in cases in parts of the world and is nicknamed “razor blade throat” COVID because it may cause painful, sharp sore throats. Doctors in the United Kingdom, India, and other countries have reported this symptom.
Where Is Nimbus Spreading?
According to the World Health Organization (WHO), Nimbus cases have increased mainly in the eastern Mediterranean, Southeast Asia, and western Pacific regions. By mid-May, this variant made up about 11% of COVID samples sequenced worldwide. In the United States, airport screenings found travelers carrying Nimbus arriving in states like California, Washington, Virginia, and New York.
Is Nimbus More Dangerous?
So far, experts say Nimbus does not cause more severe illness than other COVID variants. Some countries in the western Pacific have seen more COVID cases and hospitalizations, but there is no evidence that Nimbus leads to worse health outcomes.
Are Vaccines Effective Against Nimbus?
Yes. The WHO has labeled Nimbus as a “variant under monitoring” but considers the global health risk low. Current COVID-19 vaccines are expected to protect well against this variant.
What Should You Know?
- Nimbus may cause a very painful sore throat, sometimes described as feeling like “razor blades.”
- Other common COVID symptoms like fever, cough, chills, and loss of taste or smell still apply.
