Can You Get Chlamydia From Kissing or Oral Sex?

Quick answer
No, you cannot get chlamydia from kissing. Chlamydia spreads through vaginal, anal, and oral sex, so oral sex can transmit it to the throat. The bacteria does not travel through saliva or mouth-to-mouth contact. Testing is the only reliable way to know if an exposure led to infection.
Can you get chlamydia from kissing?
No. Chlamydia is not transmitted through kissing, including deep or open-mouth kissing. The bacteria does not spread through saliva, and mouth-to-mouth contact is not a route of transmission. Chlamydia requires direct contact with infected genital or anal fluids, which kissing does not provide. You also cannot get chlamydia from toilet seats, pools, or shared towels. The infection is almost always the result of sexual contact.
Can you get chlamydia from oral sex?
Yes. Chlamydia can infect the throat through oral sex, and it can infect the genitals through oral contact as well. The bacteria spreads through vaginal, anal, and oral sex, so no form of unprotected sex is risk-free. Throat infections usually cause no symptoms, which means they can go unnoticed and be passed on. Testing with a swab or urine sample is the only way to know whether oral exposure led to infection.
How is chlamydia transmitted?
Chlamydia spreads through vaginal, anal, and oral sex with an infected partner. It is caused by the bacterium Chlamydia trachomatis, and it is the most-reported bacterial STI in the United States, with about 1.6 million cases reported each year. The infection can be passed even when the infected person has no symptoms, which is true for about 75% of women and 50% of men. Condoms reduce the risk substantially when used consistently.
Can you get chlamydia without sex?
Essentially no. Chlamydia is a sexually transmitted infection, and it requires sexual contact with an infected person. It does not survive on surfaces, so toilet seats, pools, and shared towels pose no real risk. The bacteria needs the warm, moist environment of the genital, anal, or throat tissues to survive. If you have chlamydia and have not had sex recently, the more likely explanation is a previous exposure that was never detected.
How do you know if you have oral chlamydia?
Oral chlamydia almost never causes symptoms, so you usually cannot tell by how you feel. A mild sore throat is possible but rare, and it is easy to dismiss. The reliable way to detect it is a NAAT test, which can use a throat swab or urine sample, and it is accurate about 1 to 2 weeks after exposure. If you have had oral sex with a new or untested partner, testing is the only way to know your status.
