Yes Chlamydial can be treated.
Chlamydial infection is treated with antibiotics taken by mouth (usually a single dose). Your sexual partner(s) should be checked and treated as well. It is important to avoid sexual intercourse and oral sex during treatment and for 7 days after the end of treatment. It’s a good idea to be retested in three months to make sure the infection has been cured and that you have not been reinfected.
