Pharyngitis is inflammation of the pharynx—the back of the throat. This can cause a sore throat, as well as scratchiness in the throat and difficulty swallowing.
According to the University of Maryland Medical Center, pharyngitis is one of the most common reasons for doctor visits (UMM, 2011). More cases of pharyngitis occur during the colder months of the year.
Viruses are the most common cause of sore throats, but some sore throats are caused by bacterial infections.
Individuals who are frequently exposed to colds and flus, such as healthcare workers or children in day care are the most likely to develop pharyngitis. Individuals who have allergies, experience frequent sinus infections, or who have been exposed to second-hand smoke are also more likely to develop pharyngitis.
Pharyngitis is most commonly caused by viral infections such as the common cold, influenza, or mononucleosis. Viral infections do not respond to antibiotics, and treatment is only necessary to help relieve symptoms.
Less commonly, pharyngitis is caused by a bacterial infection. Bacterial infections do require antibiotics. The most common bacterial infection of the throat is strep throat, which is caused by streptococcus A. Rare causes of bacterial pharyngitis include gonorrhea, chlamydia, and corynebacterium.
The symptoms that accompany pharyngitis vary depending on the underlying condition.
In addition to a sore, dry, or scratchy throat, a cold or flu may cause:
In addition to a sore throat, symptoms of mononucleosis include:
In addition to a sore throat, strep throat can cause:
If you are experiencing symptoms of pharyngitis, your doctor will look at your throat. He or she will check for any white patches, swelling, and redness. Your doctor may also look in your ears and nose. To check for swollen lymph nodes, your doctor will feel the sides of your neck.
If your doctor suspects that you have strep throat, he or she will take a throat culture. This involves using a swab to take a sample of the secretions from your throat. Most doctors are able to do a rapid strep test in the office. This test will tell your doctor within a few minutes if the test is positive for streptococcus. Your doctor may also send the swab to a lab to test for strep bacteria.
If your doctor suspects another cause of your pharyngitis, he or she may order blood work. This will involve drawing a small sample of blood from your arm or hand and sending it to a lab for testing. A simple blood test can determine whether you have mononucleosis. A complete blood count (CBC) test may be done to determine if you have another type of infection. There are numerous viral and bacterial agents that can cause pharyngitis. They include:
If your pharyngitis is caused by a bacterial infection, your doctor will prescribe antibiotics. It is important that you take the entire course of antibiotics to prevent the infection from returning or worsening. If your pharyngitis is caused by a virus, home care can help relieve symptoms.
Home care includes:
Maintaining proper hygiene can prevent many cases of pharyngitis.
To prevent pharyngitis:
Most cases of pharyngitis can be successfully treated at home. However, there are some symptoms that require a doctor visit.
