The COVID-19 virus has continued to change since it first appeared in 2019. In 2025, a new variant is spreading fast, and it brings back a troubling symptom: a severe sore throat that many people describe as feeling like swallowing razor blades. This painful condition is now nicknamed “razor blade throat”, and it’s becoming one of the first signs of infection in the latest COVID cases.
This article explains what this symptom is, why it’s linked to the latest COVID strain, and what to do if you feel it.
What Is “Razor Blade Throat”?
“Razor blade throat” is not a medical term. It describes a very sharp, intense sore throat—as if you’re swallowing broken glass or razor blades. People report:
- Burning pain when swallowing
- Raw, scratchy throat
- Feeling worse in the morning
- Little to no cough initially
This painful sore throat is now one of the first warning signs of the new COVID variant.
Is Razor Blade Throat a Symptom of COVID?
Yes. Doctors and researchers say that “razor blade throat” is a common early symptom in many new COVID-19 cases in 2025. The reason:
- This new variant seems to infect the upper respiratory tract more aggressively.
- It triggers inflammation in the throat and tonsils, even before other symptoms appear.
Many patients who tested positive recently said the sore throat was so severe it prompted them to get tested.
Common Symptoms of the New COVID Variant (2025)
The latest COVID strain is slightly different from previous ones. Here are the most reported symptoms:
Most Common Symptoms of the New Variant
| Symptom | How Common |
|---|---|
| Severe sore throat (“razor blade throat”) | Very Common |
| Fatigue | Common |
| Mild to moderate fever | Common |
| Headache | Common |
| Runny or stuffy nose | Often |
| Muscle or body aches | Sometimes |
| Dry cough | Less common |
| Nausea or upset stomach | Occasionally |
| Loss of smell/taste | Rare in 2025 variant |
This version spreads fast, but symptoms are mostly mild in vaccinated people.
How Long Does “Razor Blade Throat” Last?
Usually, this sharp sore throat lasts 2 to 4 days. It starts strong, then gradually fades. Drinking warm fluids, using throat lozenges, and resting can help reduce the pain.
When to Get Tested
You should get tested for COVID if you:
- Have a sudden, severe sore throat
- Feel unusually tired
- Have other flu-like symptoms
- Have been in contact with someone who tested positive
Even if you’re vaccinated, you can still get infected.
What to Do If You Have Razor Blade Throat
If you’re experiencing razor blade throat or any symptoms listed:
- Isolate yourself immediately
- Get a COVID test
- Drink warm liquids (like tea with honey)
- Avoid acidic or spicy food
- Use over-the-counter pain relievers (consult a doctor)
Most people recover at home without needing hospital care.

Who Is at Risk?
This COVID variant can infect anyone, but it’s worse in:
- Unvaccinated people

Are Vaccines Still Effective?
Yes. Current vaccines do not fully prevent infection, but they:
