Tonsil infection – tonsillitis
Tonsillitis refers to inflammation of the pharyngeal tonsils – glands at the back of the throat, visible through the mouth
- The inflammation may involve other areas of the back of the throat, including the adenoids and the lingual tonsils (tonsil tissue at the back of the tongue)
- There are several types of tonsillitis: acute, recurrent, and chronic tonsillitis, and peritonsillar abscess (quinsy)
- Viral or bacterial infections and immunologic factors lead to tonsillitis and its complications
- Nearly all children experience at least one episode of tonsillitis
- Due to improvements in medical and surgical treatments, complications associated with tonsillitis, including mortality, are rare
Who gets tonsillitis?
- Tonsillitis most often occurs in children, but rarely in those younger than two years old
- Tonsillitis caused by bacteria (streptococcus species) Streptococcus species typically occurs in children aged 5 to 15 years, while viral tonsillitis is more common in younger children
- A peritonsillar abscess is usually found in young adults but can occur occasionally in children
- The history often helps identify the type of tonsillitis present (i.e., acute, recurrent, chronic)
What causes tonsillitis?
Most cases of acute pharyngitis and acute tonsillitis are due to the following infections
- Bacteria cause 15-30 percent of pharyngotonsillitis cases
- The herpes simplex virus
- Streptococcus pyogenes (GABHS)
- Epstein-Barr virus (EBV) – glandular fever
- Cytomegalovirus (CMV)
- Adenovirus
- Measles virus cause
- Group B Strep is the cause for most bacterial tonsillitis – strep throat
What are the symptoms of tonsillitis?
Acute tonsillitis
- Patients have a fever, sore throat, foul breath, dysphagia (difficulty swallowing), odynophagia (painful swallowing), and tender cervical lymph nodes
- Airway obstruction due to swollen tonsils may cause mouth breathing, snoring, nocturnal breathing pauses, or sleep apnoea
- Lethargy and malaise are common
- These symptoms usually resolve in three to four days, but may last up to two weeks despite therapy
Recurrent tonsillitis
- This diagnosis is made when an individual has multiple episodes of acute tonsillitis in a year
Chronic tonsillitis
- Individuals often have chronic sore throat, halitosis, tonsillitis, and persistently tender cervical nodes
Peritonsillar abscess – quinsy throat
- Individuals often have severe throat pain, fever, drooling, foul breath, trismus (difficulty opening the mouth), and muffled voice quality, such as the “hot potato” voice (as if talking with a hot potato in his or her mouth)

Clinical symptoms of tonsillitis
- Fever and enlarged inflamed tonsils covered by pus
- Group A beta-hemolytic Streptococcus pyogenes (GABHS) can cause tonsillitis (“strep throat”) associated with the presence of palatal petechiae (tiny hemorrhagic spots, of pinpoint to pinhead size, on the soft palate)
- Neck nodes may be enlarged. A fine red rash over the body suggests scarlet fever
- GABHS pharyngitis usually occurs in children 5-15 years old
- Open-mouth breathing and muffled voice resulting from obstructive tonsillar enlargement
- The voice change with acute tonsillitis usually is not as severe as that associated with peritonsillar abscess
- Tender cervical lymph nodes and neck stiffness are often found in acute tonsillitis
- Signs of dehydration found by examination of skin and mucosa
- Red swollen tonsils that may have small ulcers on their surfaces in individuals with herpes simplex virus (HSV) tonsillitis
Glandular fever
- The possibility of infectious mononucleosis (glandular fever) due to EBV in an adolescent or younger child with acute throat infection, particularly when cervical, axillary, and/or groin nodes are tender
- Severe lethargy, malaise, and low-grade fever accompany acute tonsillitis
- A grey membrane covering tonsils that are inflamed from an EBV infection – this membrane can be removed without bleeding
- Palatal petechiae (pinpoint spots on the soft palate) may also be seen with an EBV infection
Quinsy throat
- Unilateral bulging above and to the side of one of the tonsils when quinsy (peritonsillar abscess) exists
- A stiff jaw, difficulty opening the mouth and pain referred to the ear may be present in varying severity
Treatment for tonsillitis
- Tonsillitis is usually treated with a regimen of antibiotics
- Fluid replacement and pain control are important
- Hospitalization may be required in severe cases, particularly when there is airway obstruction
- When the condition is chronic or recurrent, tonsillectomy – a surgical procedure to remove the tonsils is often recommended
- Peritonsillar abscess may need more urgent treatment to drain the abscess
