Tonsillitis is an acute swelling and irritation (inflammation) of the tonsils. Tonsillitis is caused by a bacterial infection or a viral infection. The most common bacterial infection that causes tonsillitis is strep throat, caused by a group A streptococcal infection of the tonsils and throat.
The tonsils are two glands located in the back of the throat. The tonsils belong to the lymphatic system and the immune system and help to protect the body from upper respiratory infections. The role of the tonsils is especially important in young children. Tonsillitis can occur to anyone with tonsils but is most common in children.
When a bacterial infection or a viral infection causes tonsillitis, the throat and tonsils become red, swollen, and white patches of pus may appear on the tonsils. Other symptoms of tonsillitis include pain with swallowing, difficulty swallowing, headache, fever, and swollen glands (swollen lymph nodes). Complications of tonsillitis are possible in some cases. Complications can include cervical adenitis and tonsil abscess. For additional symptoms and more information about complications, refer to symptoms of tonsillitis.
The bacterial infections and viral infections that cause tonsillitis are contagious and spread when an infected person talks, coughs or sneezes. This shoots droplets contaminated with bacteria or a virus into the air where they can be breathed in by others. Bacterial infections and viral infections that cause tonsillitis can also spread by touching an infected person or a contaminated surface, such as a contaminated drinking glass or computer keyboard.
Making a diagnosis of tonsillitis involves taking a thorough health history, including symptoms, and performing a physical exam. This includes examining the throat for the typical signs of tonsillitis. These include swelling, redness and irritation of the throat and tonsils and the presence of pockets of pus on the tonsils.
At this time a throat culture and sensitivity is also performed. A throat culture and sensitivity involves swabbing the tonsils and tonsils with a cotton swab and growing and examining the sample under a microscope for a possible bacterial infection, such as a group A streptococcal infection. This test can take up to two days. A similar but quicker test that can be done in less than half an hour is also often performed. This is called a rapid strep test, which can check for a group A streptococcal infection.
An examination also includes feeling the lymph glands for signs of swelling.
Blood tests, may be performed If a person with tonsillitis is very ill, has a high fever, signs of an infection in other areas of the body, or has had symptoms for more than two weeks. Blood tests may include a complete blood count, which tests for an abnormally high number of white blood cells. This indicates an infectious process occurring in the body.
Because tonsillitis can mimic mononucleosis, a rapid test called a monospot may also be done to check for mononucleosis. A monospot test might be performed in conjunction with a blood test that checks for the presence of specific antibodies that the body produces to fight mononucleosis.
It is possible that a diagnosis of tonsillitis can be delayed or overlooked because the symptoms may resemble symptoms of other diseases, such as mononucleosis. For information about misdiagnosis and diseases and conditions that can mimic tonsillitis, refer to misdiagnosis oftonsillitis.
Treatment of tonsillitis includes measures to help relieve symptoms and keep the body as strong as possible to minimize the risk of developing complications. This includes rest, medications to ease body aches and fever, and drinking plenty of fluids. People who are in good health can generally recover from the tonsillitis at home with supportive care, such as rest, fluids, and pain relievers. Antibiotics are only prescribed if the tonsillitis is caused by a bacterial infection, such as in strep throat. Surgery may be necessary in some cases.
