Past infection does not make a person immune to chlamydia. Thus, a person can get chlamydia more than once. Chlamydia infections can be treated with several different drugs. Because it is often present with other sexually transmitted diseases such as gonorrhea, your health care provider may prescribe more than one drug for you to take at the same time. PID may damage the reproductive organs, which can cause problems in pregnancy or even leave the women unable to have a baby.
Abstinence is the only sure way to avoid STDs.
Try to limit your exposure to STDs. Unprotected sexual activity increases your chance of exposure and infection. Use barrier protection, like a condom. Look at your partner before having sex. If you see any sign of an infection such as rashes, sores, discharge or swelling, stop and talk about the importance of checking for an STD before having sex.
