Strep throat

Common Name(s)

Strep throat, Strepococcal pharyngitis

Strep throat is a bacterial infection that causes a sore throat. Not all sore throats are caused by a strep infection. In fact, most sore throats are caused by a viral infection. Step throat is caused by a specific type of bacteria, known as streptococcus pyogenes (group A streptococcus). Strep is spread easily through airborne droplets when an infected individual breathes, sneezes or coughs (highly contagious). The bacteria can also be transmitted through shared food and drink or even by touching an infected surface. The most common symptoms of strep throat include a sudden and severe sore throat, pain with swallowing, fever, swollen tonsils, and white or yellow spots on the back of throat. Risk factors for strep throat include being between the ages of 5 and 15 years and the time of year (strep is more common in spring and fall).

Your doctor may suspect strep throat based on a physical examination and the type of symptoms. However, the symptoms and an exam may not be enough to determine the reason for your sore throat. To confirm the diagnosis, your doctor may choose to swab some secretions from the back of your throat to see if they grow strep bacteria (throat culture). This can take a few days to get results. Another option, known as the rapid antigen test, uses the swab and looks for substances (antigens) in the throat. Even though this test is faster, it may miss a strep throat infection. Strep throat infections are usually treated with an oral antibiotic medication (penicillin or amoxicillin). There are also over-the-counter medications, such as Advil, Motrin, or Tylenol, that can be used to relieve some of the symptoms of strep throat. If you or your child has been diagnosed with strep throat, talk to your doctor to determine which treatment option is best.
