Chancroid – Chancroid is caused by a type of bacteria called Haemophilus ducreyi. It is almost always spread through sexual contact. Uncircumcised men are at much higher risk than circumcised men for getting chancroid from an infected partner. Most people in the U.S. who are diagnosed with chancroid have traveled outside the country to areas where the disease is known to occur more often.
Chlamydia – Chlamydia is a disease caused by the bacteria Chlamydia trachomatis. It is most commonly sexually transmitted. Chlamydia can infect the penis, vagina, cervix, anus, urethra, eye, or throat.
Cytomegalovirus (CMV) – Cytomegalovirus (CMV) is a virus that is transmitted through many bodily fluids. It is usually spread during casual contact, and it can also be transmitted during sex.

Donovanosis – Donovanosis or granuloma inguinale is a rare bacterial infection that is spread through oral, vaginal, and anal sex. Affecting far more men than women, it is had to diagnose, because the bacteria is hard to detect from a culture or biopsy. Symptoms include beefy, red ulcers on the genitals, and it is often mistaken for Chancroid or LGV.
Genital Warts (HPV) – Genital Warts are soft growths on the skin and mucus membranes of the genitals. They may be found on the penis, vulva, urethra,vagina, cervix, and around and in the anus. The virus that causes genital warts is called human papillomavirus (HPV). Not all types of HPV cause genital warts. Certain types of HPV can lead to precancerous changes in the cervix, cervical cancer, or anal cancer. These are called high-risk types of HPV.

Gonorrhea (‘The Clap’) – Gonorrhea is caused by the bacteria Neisseria gonorrhoeae. Anyone who has any type of sex can catch gonorrhea. The infection can be spread by contact with the mouth, vagina, penis, or anus.
Hepatitis (A, B & C) – Hepatitis is swelling and inflammation of the liver. Hepatitis can be caused by infections from viruses (such as hepatitis A, B, or C), bacteria, parasites, or other factors. Hepatitis A can be transmitted if you participate in sexual practices that involve oral-anal contact. Hepatitis B infection can be spread through having contact with the blood, semen, vaginal fluids, and other body fluids of someone who already has a hepatitis B infection. Hepatitis C can be spread through having unprotected sexual contact with a person who has hepatitis C (this risk is much less common than hepatitis B, but the risk is higher for those who have many sex partners, already have a sexually transmitted disease, or are infected with HIV).
Herpes (HSV1 & HSV2) – Herpes is caused by the herpes simplex virus type 1 and type 2 (HSV-1 & HSV-2). HSV-1 usually affects the mouth and lips and causes cold sores or fever blisters. However, it can spread from the mouth to the genitals during oral sex. HSV-2 most often causes genital herpes. HSV-2 can be spread through secretions from the mouth or genitals. You may become infected with herpes if your skin, vagina, penis, or mouth comes into contact with someone who already has herpes. You are most likely to get herpes if you touch the skin of someone who has herpes sores, blisters, or a rash. However, the herpes virus can still be spread even when no sores or other symptoms are present.
HIV & AIDS – HIV infection is a condition caused by the human immunodeficiency virus (HIV). HIV can be spread by the following: Through sexual contact – including oral, vaginal, and anal sex; Through blood – through blood transfusions, accidental needle sticks, or needle sharing; From mother to child – a pregnant woman can transmit the virus to her fetus through their shared blood circulation, or a nursing mother can pass it to her baby in her breast milk. Almost all people infected with HIV will develop AIDS if not treated. However, there is a small group of people who develop AIDS very slowly, or never at all. These patients are called long-term non-progressors.
HTLV – The Human T Lymphotropic Virus (type 1 and type 2), or HTLV-1 and HTLV-2 is fairly common in certain areas of the world like Japan, the Caribbean, Africa, parts of South America, eastern Siberia, and the Pacific islands and less common (fewer than 1% of the population infected) in other parts of the world. In rare instances, HTLV can develop into: Adult T-cell Leukemia/Lymphoma (ATLL), a form of cancer of the blood; HTLV-I-associated myelopathy (HAM), an inflammation of the nerves; or other associated diseases, like Strongyloidiasis.
Human Papillomavirus (HPV) – There are more than 70 types of the Human Papillomavirus (HPV). Some types produce warts — plantar warts on the feet and common hand warts. About 40 types of HPV can infect the genital area — the vulva, vagina, cervix, rectum, anus, penis, or scrotum. HPV infection spreads from one person to another through sexual contact involving the anus, mouth, or vagina. Certain types of HPV can lead to precancerous changes in the cervix, cervical cancer, or anal cancer. These are called high-risk types of HPV.

Intestinal Parasites – Intestinal parasites are microscopic, one-cell animals called protozoa. They infect the intestines. Intestinal parasites are often transmitted by contaminated food and water and during nonsexual, intimate contact. They may also be transmitted sexually.

Lymphogranuloma Venereum (LGV) – Lymphogranuloma Venereum (LGV) is a chronic (long-term) infection of the lymphatic system caused by three different types of the bacterium Chlamydia trachomatis. The bacteria spreads through sexual contact. The infection is not caused by the same bacteria that causes genital chlamydia.

Molluscum Contagiosum – Molluscum Contagiosum is a viral skin infection that causes raised, pearl-like papules or nodules on the skin. The virus can spread through contact with an infected person, and contaminated objects; such as towels, clothing, or toys. The virus also spreads by sexual contact.

Mononucleosis (‘Mono’) – Mononucleosis is a viral infection causing fever, sore throat, and swollen lymph glands, especially in the neck. Mononucleosis, or ‘mono’, is often spread by saliva and close contact. It is known as “the kissing disease,” and occurs most often in those age 15 to 17. However, the infection may develop at any age.

Mycoplasma Genitalium – Mycoplasma Genitalium is a bacterium that can infect the urethra, cervix, throat and anus. Mycoplasma genitalium is often associated with bacterial vaginosis (BV) and pelvic inflammatory disease (PID) in women, and is a common cause of non-gonococcal urethritis in men. It has only recently been identified as a sexually transmitted infection (STI). It is spread through vaginal, anal or oral sex. It can also be transmitted by sex toys and hands and fingers if they have been in contact with an infected person’s genitals or anus.

Nongonococcal Urethritis (NGU) – NGU (Nongonococcal Urethritis) is an infection of the urethra caused by pathogens (germs) other than gonorrhea. Pathogens that can cause NGU include but are not limited to: Chlamydia (most common), Herpes simplex virus (rare), & Mycoplasma genitalium.

Pelvic Inflammatory Disease (PID) – Pelvic Inflammatory Disease (PID) occurs when bacteria moves from the vagina or cervix into the uterus, fallopian tubes, ovaries, or pelvis. Most cases of PID are due to the bacteria that causes chlamydia and gonorrhea.

Pubic Lice (‘Crabs’) – Pubic Lice are small, six-legged creatures that infect the pubic hair area and lay eggs. Infestation is found mostly in teenagers and usually spreads during sexual activity.

Scabies – Scabies is an easily spread skin disease caused by a very small species of mite. Scabies is spread by skin-to-skin contact with another person who has scabies.
Syphilis – Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It has often been called “the great imitator” because so many of the signs and symptoms are indistinguishable from those of other diseases. Syphilis is passed from person to person through direct contact with a syphilis sore through vaginal, anal, or oral sex.
Trichomoniasis (‘Trich’) – Trichomoniasis is a sexually transmitted infection (STI) caused by the parasite Trichomonas vaginalis. Transmission includes penis-to-vagina, intercourse, or vulva-to-vulva contact. The parasite cannot survive in the mouth or rectum.

Vaginitis (BV, Yeast, Etc.) – Vaginitis can affect women of all ages and is extremely common. It can be caused by bacteria, yeasts, viruses, and other parasites. Some sexually transmitted infections (STIs) can also cause vaginitis, as can various chemicals found in bubble baths, soaps, and perfumes. Environmental factors such as poor hygiene and allergens may also cause this condition.
Zika – The Zika virus is primarily transmitted by infected mosquitoes but can also be transmitted sexually through bodily fluids. Zika usually does not cause noticeable signs or symptoms, but it can adversely affect pregnant women and their unborn children.
