Clinical Information
  • A disorder acquired through sexual contact.
  • Any contagious disease acquired during sexual contact; e.g. Syphilis, gonorrhea, chancroid.
  • Diseases due to or propagated by sexual contact.
  • Sexually transmitted diseases (stds) are infections that you can get from having sex with someone who has the infection. The causes of stds are bacteria, parasites and viruses. There are more than 20 types of stds, including
    • chlamydia
    • gonorrhea
    • genital herpes
    • hiv/aids
    • hpv
    • syphilis
    • trichomoniasis
    most stds affect both men and women, but in many cases the health problems they cause can be more severe for women. If a pregnant woman has an std, it can cause serious health problems for the baby.if you have an std caused by bacteria or parasites, your health care provider can treat it with antibiotics or other medicines. If you have an std caused by a virus, there is no cure. Sometimes medicines can keep the disease under control. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading stds. Centers for Disease Control and Prevention.
