Q. What causes STDs?

A. STDs are caused by bacteria and viruses. STDs caused by bacteria include chlamydia ("kla-mi-dee-a"), gonorrhea ("gon-or-ree-a"), trichomoniasis ("trik-o-mo-ni-a-sis"), and syphilis ("si-fi-lis"). These STDs can be treated and cured with antibiotics.

STDs caused by viruses include HIV/AIDS, genital herpes, genital warts, and cytomegalovirus ("si-to-meg-a-low-vi-rus"). These STDs can be controlled, but not cured. There is no way to get any of these viruses out of a person's body once he or she has become infected. Finding and treating STDs early is the best way to take care of you.
