I was treated for chlamydia, & 6days after i had taken the two one dose pills, i let a guy do oral on me.what are the chances i gave him chlamydia?

See answer: It is recommended to abstain from sexual contact for 7 days after treatment for Chlamydia. Oral transmission of Chlamydia can and does occur but is less common than other routes. Symptoms usually include sore throat and sometimes flu-like symptoms within 1-3 weeks. Given your history and the above facts, I feel the risk of transmission is likely quite low, though relaying this info recommended.

Little risk: The cure works almost right away. By six days out there is very little chance that you still had chlamydia.
