Tonsillitis Types refer to the different forms of inflammation affecting the tonsils. The main types include acute, chronic, and recurrent tonsillitis. Acute tonsillitis is a sudden infection causing sore throat, fever, and swollen tonsils, usually due to viral or bacterial infections. Chronic tonsillitis persists for long periods, leading to bad breath, persistent sore throat, and enlarged tonsils. Recurrent tonsillitis occurs multiple times a year, often requiring medical intervention. Identifying tonsillitis types helps in determining the best treatment, whether through antibiotics, home remedies, or, in severe cases, tonsillectomy. Proper diagnosis ensures effective management and relief from symptoms.
Tonsillitis Types
Tonsillitis is the inflammation of the tonsils, which are two lymph nodes located at the back of the throat. It is a common condition, especially in children, and can be caused by either bacterial or viral infections. Understanding the differences between the two is crucial for proper diagnosis and treatment.
1. Viral Tonsillitis
Most cases of tonsillitis (about 70%) are viral in origin.
Common Viral Causes:
-
Rhinovirus (common cold)
-
Adenovirus
-
Influenza virus (flu)
-
Epstein-Barr virus (EBV) (causes infectious mononucleosis, or "mono")
-
Herpes simplex virus (HSV)
-
Coxsackievirus (can cause herpangina)
Symptoms of Viral Tonsillitis:
✔ Sore throat
✔ Red, swollen tonsils (sometimes with white patches)
✔ Mild to moderate fever
✔ Runny or stuffy nose
✔ Cough
✔ Hoarseness
✔ Conjunctivitis (in adenovirus infections)
✔ Fatigue (more pronounced in EBV/mono)
Diagnosis:
-
Based on symptoms and physical examination.
-
No rapid test for most viral causes (except EBV, which may require a monospot test).
-
Throat swab may be done to rule out bacterial infection.
Treatment:
-
Supportive care (rest, fluids, warm saltwater gargles).
-
Pain relief (acetaminophen, ibuprofen).
-
No antibiotics (ineffective against viruses).
-
Symptoms usually resolve within 7–10 days.
2. Bacterial Tonsillitis
About 15–30% of tonsillitis cases are bacterial, with Group A Streptococcus (GAS) being the most common cause.
Common Bacterial Causes:
-
Group A Streptococcus (Streptococcus pyogenes) – Causes strep throat.
-
Staphylococcus aureus (less common)
-
Haemophilus influenzae
-
Mycoplasma pneumoniae
Symptoms of Bacterial Tonsillitis:
✔ Severe sore throat
✔ High fever (>38.5°C or 101.3°F)
✔ Swollen, red tonsils with white or yellow pus patches
✔ Tender, enlarged lymph nodes in the neck
✔ Absence of cough (more typical of viral)
✔ Headache
✔ Nausea/vomiting (more common in children)
✔ Bad breath
Diagnosis:
-
Rapid Strep Test (quick but may give false negatives).
-
Throat Culture (gold standard, takes 24–48 hours).
-
McIsaac Score (clinical scoring system to predict bacterial infection).
Treatment:
-
Antibiotics (Penicillin or Amoxicillin for Strep; alternatives for allergies).
-
Pain relief (NSAIDs like ibuprofen).
-
Untreated bacterial tonsillitis can lead to complications like:
-
Rheumatic fever
-
Peritonsillar abscess (quinsy)
-
Post-streptococcal glomerulonephritis
-
Key Differences Between Viral and Bacterial Tonsillitis
| Feature | Viral Tonsillitis | Bacterial Tonsillitis |
|---|---|---|
| Cause | Viruses (e.g., adenovirus, EBV) | Bacteria (e.g., Group A Strep) |
| Onset | Gradual | Sudden |
| Fever | Mild to moderate | High fever |
| Cough | Common | Rare |
| Runny Nose | Yes | No |
| Tonsil Appearance | Red, swollen (sometimes white patches) | White/yellow pus patches |
| Lymph Nodes | Mildly tender | Very swollen and tender |
| Treatment | Supportive care | Antibiotics needed |
When to See a Doctor?
-
Difficulty breathing/swallowing
-
Persistent high fever
-
No improvement after 3–4 days
-
Severe neck swelling (possible abscess)
-
Recurrent tonsillitis (may require tonsillectomy)
Conclusion:
-
Viral tonsillitis is more common and resolves on its own.
-
Bacterial tonsillitis (strep throat) requires antibiotics to prevent complications.
-
Proper diagnosis (throat swab) is essential to avoid unnecessary antibiotic use.
