'Razor blade' sore throat: New COVID symptom everyone's talking about, explained in detail

‘Nimbus’ is on the rise. No, it’s not the Harry Potter broom that we are talking about. It’s the new COVID-19 variant around the block.Since early June, reports have emerged of a strikingly painful sore throat associated with the Omicron subvariant NB.1.8.1, unofficially dubbed Nimbus.The new COVID variant is already causing a surge, and symptoms of the infection are being dubbed as 'Razor blade', implying a severe sore throat that feels like ‘razor blades’.

The fresh wave of panic:

The new COVID-19 variant, designated NB.1.8.1 and informally known as ‘Nimbus’, has been causing a notable increase in cases across Asia and prompting monitoring from the World Health Organization (WHO). This variant is characterized by a particularly severe sore throat symptom described as feeling like ‘razor blades’, alongside traditional flu-like symptoms such as congestion, fatigue, mild cough, fever, and muscle aches.

Less common symptoms include diarrhea and nausea. The symptoms have been described in dramatic terms like “Swallowing shattered glass,” “Like razor blades” in the throat, and a sharp, stabbing pain with every swallow.Already comprising over 10% of cases in Asia, the variant has also been detected in the United States of America, Canada, and Europe. A preprint study indicates that Nimbus has high immune evasion, suggesting potential for widespread transmission.

However, WHO maintains that the current global risk is low and existing vaccines remain effective in preventing severe illness.

The rise of 'razor blade throat':

In the United States of America, Nimbus now accounts for approximately 37% of sequenced cases as of early June, and about 11% globally by mid-May, as reported by Associated Press. Although up to 70% of COVID infections include sore throat, according to UCSF, and severe throat pain appears with multiple variants, patients infected with the Nimbus variant have reported an intense sore throat, often described as feeling like swallowing shards of glass, reports have said citing doctors.The intensity of the symptom might vary – it can be mild for some, but excruciating for others – impacting their ability to talk, swallow, eat, or stay hydrated. However, the sharp pain in the throat can be so severe that it hinders speaking, eating, or staying hydrated. While sore throat has always varied in intensity among COVID-19 patients, the Nimbus variant has brought this symptom to the forefront due to its severity.

Health authorities are still evaluating how common and unique this intense sore throat is with Nimbus versus earlier strains.

“Feels like broken glasses… razor blades”

Patients suffering from the infection of the Nimbus strain have been reporting online about their experience with the ‘razor blade’ symptom, saying, “Feels like broken glasses… razor blades.”

For those experiencing the painful throat associated with the Nimbus variant, several remedies may provide relief:Over-the-counter medications: Pain relievers such as paracetamol (acetaminophen) or ibuprofen can help alleviate throat pain and reduce inflammation.Warm saltwater gargle: Gargling with warm saltwater can soothe the throat and may help reduce viral load.Throat lozenges and sprays: Products containing menthol or benzocaine can numb the throat and provide temporary relief.Hydration: drinking warm liquids like herbal teas or broths can keep the throat moist and alleviate discomfort.Humidifiers: Using a humidifier can add moisture to the air, preventing the throat from becoming dry and irritated.Apart from these convenient remedies, it's essential to monitor symptoms and consult a healthcare provider if throat pain persists or worsens.While the Nimbus variant presents a new challenge with its painful throat symptoms, understanding the condition and taking appropriate measures can help manage and alleviate discomfort. Although most cases of the Nimbus variant result in mild illness, certain signs indicate the need for medical evaluation. If the throat pain or other symptoms do not improve or worsen over time, or you experience shortness of breath or chest tightness, coupled with a fever that remains above 100°F (37.8°C) for several days – you must consult with a professional healthcare provider.

Individuals with underlying health conditions, the elderly, or those who are pregnant should seek medical advice promptly if symptoms arise.
