With nearly 3 million infections annually, chlamydia is the most common sexually transmitted bacterial infection in the United States, the Centers for Disease Control and Prevention reports. Chlamydia transmission occurs during sexual contact with the genitals, anus or mouth of an infected person -- or from a mother to her baby during birth. Oral chlamydia infections often don't cause symptoms. When they do occur, they are typically mild.
Throat and Other Symptoms
Oral chlamydia infections affect the cells lining the throat. The most common symptom is a sore throat lasting several days. This discomfort can be continuous or come and go, and swallowing may increase the discomfort. A sore throat caused by chlamydia may be accompanied by low-grade fever and swollen lymph nodes. However, most people with an oral chlamydia infection experience no symptoms, leading many to be unaware that they are infected.
Diagnosis and Treatment
Once chlamydia is diagnosed, it can be effectively treated with antibiotics. However, chlamydia can lead to serious medical complications if it remains untreated. If you think you might be infected, it is important to be tested regardless of whether you have symptoms. Check with your local health department or online with the CDC to find a testing site near you.
See your doctor if you experience a sore throat that lasts for several days, especially if you also have a fever, difficulty swallowing or other symptoms. Many different infections and other illnesses can cause a sore throat.
