The latest COVID-19 variant, NB. 1.8.1 or “Nimbus”, has been rapidly spreading in the U.S. and is associated with a severe symptom, a sore throat described as “razor blade throat”.
Since it was first discovered in the U.S. in March, NB.1.8.1 has become the nation’s dominant strain of COVID-19. It accounted for an estimated 43% of cases in June, according to the Centers for Disease Control and Prevention (CDC).
COVID-19 viruses bind to ACE2 receptors that are found on the surface of cells. Cells in the upper airway (nose and throat) have more ACE2 receptors than those in the lower airway and lungs do, making them prime targets for Omicron variants, which bind to these receptors more strongly. Research suggests that of all the variants circulating now, Nimbus binds to ACE2 receptors the most.
Once the virus reaches those cell receptors in and around your throat, the immune system kicks into overdrive to keep the virus at bay, causing inflammation, fluid buildup, redness, and swelling.
If you do experience an intense sore throat, experts recommend several remedies, including:
- Honey
- Cough drops
- Throat spray
- Gargling with salt water
- Over-the-counter pain relievers
If you do catch COVID, you may experience other common symptoms besides a sore throat, such as:
- Fever or chills
- Cough
- Congestion or a runny nose
- New loss of taste or smell
- Fatigue
- Muscle or body aches
- Headache
- Nausea or vomiting
- Diarrhea
Most healthy people will recover from COVID without treatment. However, experts still recommend talking to a healthcare provider if you test positive. Even if you are not at risk of severe illness, treatment from a healthcare provider may be able to lower your risk of long COVID.
If you are experiencing symptoms of N.B.1.8.1, such as a “razor blade throat”, you can schedule an appointment with a doctor at Flushing Hospital’s Ambulatory Care Center by calling (718) 670-5486.
