A newly identified strain of the COVID-19 virus—known as NB.1.8.1—is drawing attention from medical professionals due to a particularly severe symptom: intense throat pain often described by patients as feeling like “razor blades.” This phrase, once used anecdotally during earlier variants like Omicron, has resurfaced with greater consistency among recent cases in California and beyond.
Understanding Variant NB.1.8.1
NB.1.8.1 is part of the ever-evolving lineage of SARS-CoV-2 variants. Though not yet classified as a major “variant of concern” by the World Health Organization or CDC, it belongs to a family of subvariants descended from Omicron. While Omicron introduced milder symptoms and rapid transmission, newer offshoots like NB.1.8.1 are revealing how the virus continues to adapt in subtle yet impactful ways.
This variant has been detected in several regions of California and is characterized by a combination of symptoms, but the one standing out most—based on both anecdotal reports and clinical documentation—is the burning, raw pain in the throat. Patients liken it to swallowing shards of glass or “razor blades,” a metaphor gaining traction among healthcare workers observing the trend.
Symptoms and Transmission
Besides the hallmark throat discomfort, symptoms associated with NB.1.8.1 appear consistent with previous variants: fatigue, nasal congestion, body aches, fever, and cough. However, reports suggest that the sore throat arrives suddenly and with unusual severity, making it one of the earliest and most alarming signs for those infected.
There’s no evidence yet suggesting that NB.1.8.1 causes more severe outcomes in terms of hospitalization or mortality compared to earlier strains. Still, its capacity for causing distressing upper respiratory symptoms raises concerns, especially as colder seasons approach and respiratory viruses naturally become more active.
Preliminary data suggests that NB.1.8.1 maintains a high transmission rate, much like its Omicron predecessors. Because of this, the same preventive measures—mask-wearing in crowded spaces, frequent handwashing, and staying updated on vaccinations—remain essential tools in reducing spread.
Why the “Razor Blade” Symptom Matters
One reason the razor-like throat pain is drawing focus is its usefulness as an early diagnostic clue. Many infected individuals report the sensation as their first and most intense symptom, sometimes appearing before a positive test result. This might allow for earlier isolation and treatment, if recognized and acted upon swiftly.
From a biological standpoint, the severity of the throat pain may be linked to how the virus replicates and interacts with upper respiratory tract tissues. Further research is needed to confirm whether NB.1.8.1 has a greater affinity for certain cell types in the throat, or if the body’s immune response is behind the increased inflammation.
Public Health Considerations
Although NB.1.8.1 is not currently considered more dangerous than other circulating variants, public health officials are monitoring it closely. The emotional and physical toll of symptoms like severe throat pain should not be underestimated—especially for individuals already managing other health conditions.
Hospitals and clinics are also watching for shifts in emergency room visits or prescription trends for pain relief medications related to throat symptoms, which may serve as indirect markers of the variant’s prevalence.
For now, staying informed and cautious remains the best course of action. While NB.1.8.1 doesn’t appear to pose a larger threat than past strains, its discomforting symptom profile highlights the virus’s ongoing evolution and its unpredictable impact on individuals.
