Most people dont realize that a COVID19 infection can sometimes produce white patches on the tonsils, but its not the same as classic tonsillitis. In this post youll learn what the evidence says, how to tell COVIDrelated throat changes from strep or bacterial tonsillitis, and when you should see a clinician.
Quick Answer Overview
Short answer: COVID19 can occasionally cause white spots on the tonsils, but they are usually viral exudates rather than the thick pus youd see with bacterial tonsillitis. The spots are often small, milletsized, and may appear alongside a sore throat, mild fever, or loss of taste and smell. Most cases are mild and resolve on their own. If the spots persist beyond a week, become larger, or are accompanied by severe pain or difficulty swallowing, its time to get checked.
What research actually says
In a caseseries published on NCBI, a handful of patients infected with the Omicron variant reported tiny white specks on their tonsils that resolved within a few days. The authors noted that these spots were distinct from the classic white coat seen in streptococcal infections.

COVID Throat Effects
When youre dealing with a COVID infection, the throat can feel like a desert after a long hikedry, raw, and sometimes surprisingly painful. The typical COVIDrelated sore throat often feels like a lowgrade burn that worsens when you swallow, and you might notice a subtle hoarseness. Some people even describe a metallic taste.
Typical COVIDrelated sorethroat symptoms
Key signs include:
- Dry or gritty sensation
- Mild fever (usually under 38C)
- Occasional white or grayish spots on the tonsils
- Loss of smell or taste (what does covid sore throat feel like? is a common question on forums)
Why white spots appear
COVID is a viral infection, so its inflammation is different from the bacterial exudate you see with strep throat. The virus can cause tiny ulcerations or slough off dead cells, leaving a pale, sometimes speckled coating. Healthline describes this as viral exudate, which looks lighter and less clumped than the thick, creamy pus from a bacterial infection.
Example case study (anecdotal)
Jess, a 28yearold teacher, tested positive for COVID19 and three days later noticed a few milletsize white specks on each tonsil. She felt a scratchy throat but no severe pain. Within five days the spots faded, and the sore throat resolved without antibiotics. Jesss story illustrates how white spots can be a harmless, shortlived part of a COVID infection.
COVID vs. bacterial tonsillitis: the big differences
| Feature | COVIDrelated spots | Strep/ Bacterial Tonsillitis |
|---|---|---|
| Size & color | Small, milletsize, pale | Larger, creamywhite or yellow |
| Fever | Often lowgrade or absent | Usually 38C |
| Loss of smell/taste | Common | Rare |
| Onset | 23days after other COVID symptoms | Sudden, often after a day of sore throat |
| Duration | Usually resolves within a week | May persist or worsen without treatment |
COVID and Tonsillitis
Its natural to wonder, Can you have COVID and tonsillitis at the same time? While the two can coexist, its not common. COVID19 itself doesnt cause bacterial tonsillitis, but the temporary weakening of the immune system during a viral infection can open the door for bacteria to move in.
Coinfection likelihood
Most clinicians, including those at Cooper University Health Care, note that true bacterial tonsillitis is a separate condition. When patients have both, the bacterial infection usually shows up a few days after the viral symptoms start, and the throat pain becomes sharper.
Secondary bacterial infection warning signs
If you notice any of the following, you might be dealing with a secondary infection:
- Fever spikes above 38C and lasts more than 48hours
- Severe, worsening throat pain, especially on one side
- Swollen, tender lymph nodes in the neck
- White patches that grow larger or become pusfilled
Impact on COVID test accuracy
Theres a myth floating around that tonsillitis could cause a falsepositive COVID test. The current evidence says this isnt the case. Antigen tests look for specific viral proteins, and bacterial inflammation doesnt mimic those markers. PCR tests are even more specific, so a sore throat or tonsillitis wont make them light up incorrectly.
Related Throat Questions
People searching for does covid cause white spots on tonsils often have a handful of related queries. Lets tackle a few of the most common ones.
Can COVID cause tonsil stones?
Tonsil stones (tonsilloliths) form when debris, dead cells, and mucus get trapped in the crevices of the tonsils and harden. COVID can increase mucus production, which might give the stones a little extra fuel, but its not a direct cause. Think of it as a shortterm boost to the conditions that already exist.
Can tonsillitis cause loss of smell and taste?
Loss of smell or taste is a hallmark of COVID19, not bacterial tonsillitis. While a severely inflamed throat could temporarily affect how you perceive flavors (because youre not chewing or swallowing comfortably), true anosmia (loss of smell) is almost always linked to a viral cause, especially COVID.
Can COVID cause white spots on the throat?
Yes. The same viral exudate that shows up on the tonsils can appear on the soft palate, uvula, or the back of the throat. The patches are usually lighter and dont have the thick, chunky look of bacterial pus.

When to Seek Care
Most white spots from COVID fade on their own, but there are redflag symptoms you shouldnt ignore:
- High fever (38C) lasting more than 48hours
- Severe pain while swallowing or speaking
- Swelling that makes it hard to breathe
- White patches that grow larger or become yellow/green
- Persistent loss of taste or smell beyond two weeks
If any of these show up, schedule a visit with an ENT specialist or your primary care provider. Theyll likely do a throat swab for a rapid strep test, a COVID PCR or antigen test, and possibly a throat culture if they suspect bacterial involvement.
What to expect during a clinical exam
During the appointment youll probably hear the clinician ask you a script like:
Ive had a COVID infection a week ago and now I see white spots on my tonsils. Im also losing my sense of taste. Could this be a secondary infection?
Thats a perfect way to get the doctor on the same pageclear, concise, and focused on the symptoms that matter most.
Bottom Line Summary
COVID19 can sometimes produce white spots on the tonsils, but these are usually viral exudates, not the classic pus of bacterial tonsillitis. The spots are typically small, pale, and resolve within a week. Coinfection with true tonsillitis is possible but uncommon; watch for worsening pain, high fever, or enlarged neck nodes as signs of a secondary bacterial infection. When in doubt, especially if redflag symptoms appear, seek professional medical advice.
Understanding the difference helps you avoid unnecessary antibiotics and gives you peace of mind during an already stressful time. If youve ever noticed strange white spots after a COVID bout, share your experience with a trusted friend or a health professionalyoure not alone, and a quick chat can make all the difference.
