Sexually Transmitted Disease (STD) Control Program

Facts and Frequently Asked Questions (FAQs)

Reportable STD diseases, conditions, and infections below are listed in alphabetical order:

  • Chlamydia - If untreated, chlamydial infections can progress to serious reproductive and other health problems with both short-term and long-term consequences. Like the disease itself, the damage that chlamydia causes is often "silent."
  • Gonorrhea - Untreated gonorrhea can spread to the blood or joints. This condition can be life threatening. In addition, people with gonorrhea can more easily contract HIV, the virus that causes AIDS.
  • Hepatitis - Viral hepatitis is the leading cause of liver cancer and the most common reason for liver transplantation.
  • Herpes - Genital herpes is a common STD. While most people with genital herpes infection do not know they have it, genital herpes can cause recurrent painful genital sores in many adults, and herpes infection can be severe in people with suppressed immune systems.
  • HIV/AIDS - HIV is the human immunodeficiency virus. It is the virus that can lead to acquired immune deficiency syndrome, or AIDS. While current medications can dramatically improve the health of people living with HIV and slow progression from HIV infection to AIDS, existing treatments need to be taken daily for the rest of a person's life, need to be carefully monitored, and come with costs and potential side effects.
  • Pelvic Inflammatory Disease (PID) (when caused by gonorrhea or chlamydia infection) - Pelvic Inflammatory Disease (PID) can lead to serious consequences including infertility.
  • Syphilis - Untreated syphilis may subsequently damage the internal organs, including the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints. The syphilis bacterium can infect the baby of a woman during her pregnancy and she may have a high risk of having a stillbirth (a baby born dead) or of giving birth to a baby who dies shortly after birth.

Other STDs:

  • Bacterial Vaginosis - Any woman can get bacterial vaginosis. Learn about the signs, symptoms, transmission, treatment, prevention, and more.
  • Chancroid - Successful treatment for chancroid cures the infection, resolves the clinical symptoms, and prevents transmission to others.
  • Human Papillomavirus (HPV) - Human papillomavirus (HPV) infection is the most common sexually transmitted virus in the United States.
  • Lymphogranuloma Venereum (LGV) - LGV is passed from person to person through direct contact with lesions, ulcers or other area where the bacteria is located.
  • Pubic "Crab" Lice - Also called crab lice or "crabs," pubic lice are parasitic insects found primarily in the pubic or genital area of humans. Pubic lice infestation is found worldwide and occurs in all races, ethnic groups, and levels of society.
  • Scabies - Scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). Scabies occurs worldwide and affects people of all races and social classes.
  • Trichomoniasis - Trichomoniasis is a common sexually transmitted disease (STD) that is easy to cure.


Having an STD can make you more likely to get HIV. Find out more at the CDC's HIV/AIDS & STDs website.

It's Your Sex Life - GYT (Get Yourself Tested)

Responding to the fact that one in two young people will get a sexually transmitted disease (STD) by age 25 - and most won't know it - the GYT campaign is a youthful, empowering social movement to reduce the spread of STDs among young people through information; open communication with partners, health care providers, and parents; and testing and treatment as needed. Find a toolkit with various materials to enhance your own campaign such as buttons, stickers, videos and t-shirts at the GYT website.
