Strep throat is an infection of the throat caused by bacteria called Streptococci. There are different types of streptococci. The type that causes serious sore throats and needs to be treated with antibiotics is called group A strep.
Strep infections are very contagious. They are usually passed directly from person to person. Strep throat is common in school-age children. Children under 2 years old and adults not exposed to children are much less likely to get strep throat. It is most common from November through April, but it can happen any time of year.
The symptoms of a strep infection may include:
Your healthcare provider will ask about your symptoms and examine your throat. Usually you will have a strep test. Your provider will rub a cotton swab against a tonsil in the back of your throat to get a sample of bacteria. The sample will be tested in the lab. The results will be available in an hour or less if the rapid antibody test is done, or in 1 to 2 days if the overnight culture test is used.
If your healthcare provider suspects you have strep, he or she may prescribe an antibiotic before you have all the results from the lab tests. This medicine may be taken as pills or given as a shot. It is very important to take all of the prescribed medicine, even after the symptoms have gone away, to keep the infection from coming back. Strep needs to be treated so you can prevent serious problems it might cause, such as rheumatic fever, which can lead to heart disease.
The symptoms of strep throat may go away as soon as 24 hours after you start treatment. The symptoms rarely last longer than 5 days.
Not getting treatment for strep throat or not taking all the medicine prescribed can lead to rheumatic fever. Rheumatic fever is a reaction to strep infection that can damage the heart valves and affect your joints and nervous system.
Follow the full treatment prescribed by your healthcare provider.
For a sore throat:
If you have a fever, rest and limit your activities until the fever is gone.
Ask your healthcare provider if you can take acetaminophen, aspirin, or ibuprofen to reduce your fever and to relieve pain. Check with your healthcare provider before you give any medicine that contains aspirin or salicylates to a child or teen. This includes medicines like baby aspirin, some cold medicines, and Pepto-Bismol. Children and teens who take aspirin are at risk for a serious illness called Reye's syndrome. Nonsteroidal anti-inflammatory medicines (NSAIDs), such as ibuprofen and aspirin, may cause stomach bleeding and other problems. These risks increase with age. Read the label and take as directed. Unless recommended by your healthcare provider, do not take NSAIDs for more than 10 days for any reason.
