12 months agoUS
A new COVID-19 variant, known informally as "Nimbus" (NB.1.8.1), is rapidly spreading across the globe, sparking concerns due to a distinctive and painful symptom: a severe sore throat often described as a "razor blade sensation."

In-Depth Analysis
The Nimbus variant (NB.1.8.1) is a newly emerging strain of COVID-19 that has quickly gained traction worldwide. Health officials are closely tracking its spread and characteristics to determine its potential impact on public health.
Symptoms and Transmission:
The most notable symptom associated with the Nimbus variant is a severe sore throat, often described by patients as feeling like "swallowing razor blades or shards of glass." This intense throat pain is caused by the direct infection of cells in the throat, leading to significant irritation. In addition to the sore throat, other commonly reported symptoms include fatigue, mild cough, fever, muscle aches, and nasal congestion. Some individuals may also experience digestive issues like nausea or diarrhea.
Prevalence and Impact:
In the United States, the Nimbus variant accounted for approximately 37% of COVID-19 cases in early June 2025, according to the CDC. The UK has also seen a rise in cases and hospital admissions related to the variant. Despite the increase in cases, current data suggests that the Nimbus variant does not cause more severe illness than previous variants, and existing vaccines are expected to remain effective.
What to Do If You Suspect You Have Nimbus:
If you experience symptoms consistent with the Nimbus variant, such as a severe sore throat, it is advisable to stay home and rest. Over-the-counter pain relievers, fluids, and soothing remedies like honey and tea can help alleviate symptoms. If symptoms persist or worsen, consult a healthcare professional for a diagnosis and treatment plan. It is also important to stay up-to-date with COVID-19 vaccinations and boosters to protect against severe illness.
