Causes of Chlamydia in throat

Direct contact with the infected person or carrier of chlamydia marks the main reason for getting this bacteria. Either from the penetrative sex with the infected person or the oral sex, chlamydia can get transferred from the infected person. While pharyngeal chlamydia is less common than genital or anal Chlamydia.

According to the Centers for Disease Control (CDC), the risks of getting oral chlamydia increase if:

  • You perform oral sex on a male that has an infected penis.
  • You perform oral sex on a female with an infected vagina or urinary tract.
  • You perform oral sex on a male or female who has an infected rectum.
Are you having oral sex lately and feeling the infection in your throat? It’s a good time you get yourself checked with the healthcare provider now.

Furthermore, you are also at risk when receiving oral sex from an infected partner. Risk increases if you: 

  • Receive oral sex on the penis from a partner with Chlamydia in the throat.
  • Receive oral sex on the vagina from a partner with Chlamydia in the throat. This can result in Chlamydia of the vagina or urinary tract.
  • Receive oral sex on the anus from a partner with Chlamydia in the throat.

On both ends, performing or receiving any sexual activity with the infected or carrier person of chlamydia will be the cause of the pharyngeal chlamydia.
