Nimbus COVID Variant Brings Razor Blade Throat: What You Need to Know

A new COVID-19 variant, dubbed NB.1.8.1 or "Nimbus," is slicing through the U.S., making up roughly 37% of cases in the two weeks ending June 7, according to the CDC. What sets this strain apart? A vicious sore throat that patients liken to swallowing razor blades or shards of glass, earning it the grim nickname "razor blade throat."

While Nimbus is more transmissible, it doesn’t appear to pack a deadlier punch than prior variants. Dr. Marc Siegel, a trusted voice in medicine, notes it’s not making people sicker overall, but that sore throat is a standout. "Excruciating" is how some describe it, with social media buzzing—Google Trends shows spikes in searches for "razor blade throat COVID," and Reddit users swap stories of throat pain so intense it feels like a personal attack.

Dr. Kenneth Perry, an ER physician in South Carolina, explains that the virus directly irritates throat cells, causing this hallmark symptom. But don’t jump to conclusions—sore throats aren’t exclusive to COVID. Pharyngitis, the medical term, can stem from bacteria, allergies, or even acid reflux. Still, Perry says viruses like COVID cause most cases, with about 20% tied to bacterial infections.

Treatment? It’s a mix of old-school remedies and modern medicine. Honey is a go-to for soothing throats and calming coughs, while anti-inflammatories like ibuprofen can dull the pain. For bacterial causes, antibiotics might be needed; acid reflux may just need an antacid. Staying hydrated is critical, as swallowing can become a chore. Gargling with a saltwater mix—½ teaspoon salt per cup of water—can also ease the burn, per Cleveland Clinic wisdom.

With Nimbus spreading fast, doctors urge anyone with severe throat pain to seek a proper diagnosis. This variant may not be more lethal, but it’s certainly leaving its mark—one painful swallow at a time.
