Anewly emerging COVID-19 variant, identified as NB.1.8.1 and informally called "Nimbus," is believed to account for nearly one-third of current cases, according to health authorities. Data suggests that during a recent two-week period ending in early June, this variant represented approximately 37% of infections in the United States.
While the new strain appears to spread more easily, it does not seem to cause more severe illness compared to previous variants. One of its most distinctive symptoms is an intensely painful sore throat, often described by patients as feeling like swallowing razor blades or shards of glass—a sensation now commonly referred to as "razor blade throat."
Medical experts explain that this extreme throat pain stems from direct infection and irritation of the throat's cells. Unlike earlier variants where fever or body aches were more dominant, this strain has brought sore throat back to the forefront of its symptom profile.
Despite the severity of the throat pain, it’s important to note that not all sore throats are caused by COVID-19. Pharyngitis, or inflammation of the throat, can result from various sources including bacterial infections, allergies, or acid reflux. While approximately 20% of sore throats may be bacterial, most are viral in nature.
Treatment largely depends on the underlying cause. For viral sore throats such as those caused by COVID-19, symptom relief typically involves a combination of home remedies and over-the-counter medications. Honey is often recommended to soothe the throat and suppress coughing, while anti-inflammatory medications like ibuprofen or naproxen can help reduce pain and inflammation. Drinking warm liquids, such as tea with lemon and honey, may also provide comfort.
In more severe cases where the pain makes it difficult to swallow liquids or medication, patients may risk dehydration and require medical attention. For bacterial infections, antibiotics may be prescribed, and acid reflux-related throat pain can often be managed with antacids.
Simple home remedies such as gargling with salt water—a mixture of half a teaspoon of salt in one cup of warm water—can help reduce inflammation and irritation. Additionally, using lozenges, staying well-hydrated, and applying numbing throat sprays may offer further relief.
As this variant continues to circulate, health professionals stress the importance of seeking medical advice for persistent or severe symptoms to ensure proper diagnosis and treatment.
