Chlamydia is the most frequently reported bacterial STI in the United States. The Centers for Disease Control and Prevention (CDC) estimate there were 4 million chlamydia infections in the country in 2018. However, experts believe the actual figure is higher because not everyone will show symptoms and therefore may not get tested.
The CDC also states that chlamydia is more common in young people, with two-thirds of new infections occurring among those aged 15–24 years. Like most STIs, the infection passes from person to person through sexual contact with the penis, vagina, anus, or mouth.
Although chlamydia of the throat is uncommon, it is possible to contract it from a sexual partner by giving oral sex to a partner who has chlamydia through their penis, vagina, or rectum. A person can also acquire it by receiving oral sex on the penis, vagina, or rectum from a partner who has chlamydia in the throat.
Most chlamydia infections are asymptomatic and show no symptoms. If a person does experience symptoms, they may include:
It is also possible to have chlamydia in the throat and the genitals at the same time.
Chlamydia of the throat can also be asymptomatic, but symptoms may include a sore throat or mouth and swollen lymph nodes.
