Sore Throat and Strep Throat

Prevention - Home Treatment - When to Call a Health Professional

Most sore throats are caused by viruses and may occur with a cold or may follow a cold. A mild sore throat may be caused by dry air, smoking, air pollution, or yelling. People who have allergies or stuffy noses may breathe through their mouths while sleeping, which can cause a mild sore throat.

Strep throat is a sore throat caused by streptococcal bacteria. It is more common in children from 3 to 15 years of age. A person can get strep throat even if his or her tonsils have been removed.

In general, the more coldlike your symptoms are, the less likely it is that you have strep throat. Strep throat causes some or all of these symptoms:

Prevention

  • Drink 8 to 12 glasses of water a day.

  • Identify and avoid irritants that cause sore throat (such as smoke, fumes, or yelling). For tips on quitting smoking, See Be Tobacco-Free.

  • Avoid contact with people who have strep throat.

  • If you have mono, try to keep from spreading the virus: don't share eating or drinking utensils; avoid kissing; and do not donate blood until your symptoms are gone and you are feeling better.

Home Treatment

Home care is usually all that is needed for viral sore throats. If you are taking antibiotics for strep throat, these tips will also help you feel better.

  • Gargle with warm salt water ( 5 ml or 1 tsp of salt in 240 ml or 8 oz of water). The salt reduces swelling and discomfort.

  • If you have postnasal drip, gargle often to prevent more throat irritation.

  • Drink more fluids to soothe your sore throat. Honey and lemon in hot water or in weak tea may help. Do not give honey to children younger than 1 year of age.

  • Stop smoking, and avoid other people's smoke.

  • Acetaminophen, aspirin, or ibuprofen will relieve pain and reduce fever. Do not give aspirin to anyone younger than 20.

  • Some nonprescription throat lozenges (such as Sucrets Maximum Strength, Cepacol, and Halls Mentho-Lyptus) are safe, effective, and have a local anaesthetic to soothe pain. Regular cough drops or hard candy may also help.
