Tonsillitis is inflammation of the tonsils that commonly causes sore throat, difficulty swallowing and fever. It can result from viral or bacterial infections and varies in severity and duration. Below is general information on typical symptoms, likely causes, how it’s assessed, and which specialties may be involved in care.
What tonsillitis is and how it typically progresses
Tonsillitis refers to infection or inflammation of the tonsil tissue. It may present as an acute episode that resolves over days, or as recurrent episodes in some people. Children are often affected but adults can develop it too. Severity ranges from mild throat discomfort to more severe pain and system-wide symptoms.
Common causes and how it spreads
Both viruses and bacteria can cause tonsillitis. Streptococcal bacteria are a common bacterial cause, while many respiratory viruses may also lead to tonsil inflammation. The condition spreads through respiratory droplets and close contact; contaminated hands and surfaces can also transmit pathogens. Factors such as tobacco smoke exposure and weakened immunity can increase risk.
Typical symptoms and warning signs
Typical symptoms include sore throat, painful swallowing, fever, red or swollen tonsils, white spots or coatings on the tonsils, and tender neck lymph nodes. Warning signs that require prompt medical attention include breathing difficulty, inability to keep down fluids, sudden marked worsening with high fever, drooling or altered consciousness. If these occur seek urgent care or emergency services.
Diagnosis and which doctors to consult
Diagnosis often begins with a clinical exam of the throat and neck; swabs or lab tests may be used when a bacterial cause is suspected. Primary care (family medicine) is a suitable first contact. Based on findings, referral to an Ear, Nose and Throat (ENT) specialist or Infectious Diseases clinic may be appropriate, especially for recurrent, severe or complicated cases.
Prevention and everyday measures
Simple measures can reduce spread: good hand hygiene, avoiding close contact with people who are symptomatic, and not sharing utensils or towels. Avoiding tobacco smoke and keeping general health measures that support the immune system also help. When symptoms worsen or you are uncertain, contact a healthcare professional for guidance.
