Sore Throat

What causes sore throat?

Sore throat, or pharyngitis, is an infection of the throat and sometimes tonsils. It is most commonly caused by bacteria called Streptococcus, which then becomes known as "strep throat." Strep throat can cause severe complications such as rheumatic fever (a disease of the heart valves), so it is important to seek prompt treatment for your child.

What are the signs and symptoms?

  • Redness in the back of the throat
  • Fever (temperature above 100° F)
  • Loss of appetite
  • Painful swallowing
  • Stomach ache
  • Headache
  • Swollen glands in the neck
  • Tires easily

How will I know if my child has strep throat?

Your child’s doctor will perform a throat culture to see if the sore throat is being caused by Streptococcus bacteria. After a cotton swab is rubbed across the back of the throat, it will be sent to a lab for testing. If the results of the strep test are positive, the doctor may prescribe antibiotics for your child. Strep throat is spread through contact with saliva and mucus, and is still contagious until antibiotics have been taken for 24 hours.

How can I care for my child at home?

  • Give your child all medication as instructed by the doctor.
  • Give your child acetaminophen for fever. Do not give your child aspirin.
  • Make sure your child drinks plenty of fluids.
  • Soft or cold foods, like pudding and milkshakes, may help ease throat pain.
  • Give children over eight years of age warm salt water to gargle (with ¼ teaspoon of salt per glass of water).
  • Suck on hard candy or throat lozenges if older than 4 years of age.

Call the doctor if your child has:

  • A fever after taking antibiotics for two days
  • Increased throat pain
  • Earache
  • A hard time breathing
  • Skin rash
  • Excessive drooling
  • Cough
  • Severe headache
  • Shortness of breath
  • Dark urine, rash, or chest pain (may occur three to four weeks later)
  • Sore throat that lasts longer than 4 days

Questions to ask your child’s doctor

  • Should I give my child medication? If so, for how long and how often?
  • How should I store the medication? Should I refrigerate it?
  • When will my child start to feel better?
  • Should I keep my child home from school or daycare?
  • Should he or she be limited from certain activities? If so, which ones?
  • Are there certain foods or liquids he or she should have or avoid?
  • Which over-the-counter pain relievers do you recommend?
  • Which symptoms should I report to you/your office?
