Chlamydia is a common STD caused by the bacterium
called Chlamydia trachomatis. Can be transmitted during vaginal, anal, or oral sex. - It can be transmitted without complete insertion of a penis into the vagina or anus. It is less likely, although possible, to be transmitted to the throat during oral sex.
Chlamydia can also be spread from mother to baby during delivery. Chlamydia is known as a “silent” disease because about three quarters of infected women and about half of infected men have no symptoms. If symptoms do occur, they usually appear within 1- 3 weeks after exposure. Men with signs or symptoms might have a discharge from their penis or a burning sensation when urinating. Chlamydia infections are treatable and curable with antibiotics .
An STD caused by a type of bacteria called Treponema pallidum. Syphilis is passed from person to person through direct contact with syphilis sore. Sores occur mainly on the external genitals, vagina, anus, or in the rectum. Sores also can occur on the lips and in the mouth. Transmission of the organism occurs during vaginal, anal, or oral sex. Pregnant women with the disease can pass it to the babies they are carrying. Syphilis cannot be spread through contact with toilet seats, doorknobs, swimming pools, hot tubs, bathtubs, shared clothing, or eating utensils. Syphilis infections are treatable and curable with antibiotics.
Primary Stage
The primary stage of syphilis is usually marked by the appearance of a single sore (called a chancre), but there may be multiple sores. The time between infection with syphilis and the start of the first symptom can range from 10 to 90 days (average 21 days). The chancre is usually firm, round, small, and painless. It appears at the spot where syphilis entered the body. The chancre lasts 3 to 6 weeks, and it heals without treatment. However, if adequate treatment is not administered, the infection progresses to the secondary stage.
Secondary Stage
Skin rash and mucous membrane lesions characterize the secondary stage. This stage typically starts with the development of a rash on one or more areas of the body. The rash usually does not cause itching. Rashes associated with secondary syphilis can appear as the chancre is healing or several weeks after the chancre has healed. The characteristic rash of secondary syphilis may appear as rough, red, or reddish brown spots both on the palms of the hands and the bottoms of the feet. However, rashes with a different appearance may occur on other parts of the body, sometimes resembling rashes caused by other diseases. Sometimes rashes associated with secondary syphilis are so faint that they are not noticed. In addition to rashes, symptoms of secondary syphilis may include fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue. The signs and symptoms of secondary syphilis will resolve with or without treatment, but without treatment, the infection will progress to the latent and late stages of disease.
Late Stage
The latent (hidden) stage of syphilis begins when secondary symptoms disappear. Without treatment, the infected person will continue to have syphilis even though there are no signs or symptoms; infection remains in the body.

In the late stages of syphilis, it may subsequently damage the internal organs, including the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints. This internal damage may show up many years later. Signs and symptoms of the late stage of syphilis include difficulty coordinating muscle movements, paralysis, numbness, gradual blindness, and dementia. This damage may be serious enough to cause death.

Pubic lice and Scabies
Also called “crabs,” pubic lice are parasitic insects found in the genital area of humans. Pubic lice are usually spread through sexual contact. Rarely, infestation can be spread through contact with an infested person’s bed linens, towels, or clothes. Crabs are very small bugs that attach themselves to pubic hair and bite the surrounding skin.

Scabies is an infestation of the skin with the microscopic mite Sarcoptes scabei. By direct, prolonged, skin-to-skin contact with a person already infested with scabies. Scabies are mites (bugs) that dig under the skin where they lay their eggs, often in the genital area.

There are both over-the-counter prescription creams available to get rid of crabs and scabies. Use as directed by your medical provider. You must also wash your clothing, bedding, and towels in hot water to avoid re-infection.

Non-Gonoccochal Urethritis (NGU)
Also called non-specific urethritis, this is an infection in the male urethra caused by bacteria such as Chlamydia, Mycoplasma, Ureaplasma or Trichomoniasis. NGU is passed from one person to another during anal, vaginal and possibly oral sex. Symptoms may include a mild discharge from the head of the penis that goes away after a few days and pain or burning upon urination. Antibiotics are used to cure NGU.

Also known as trich, this is an infection caused by a protozoon that is passed from person to person during vaginal sex. Women have more symptoms than men; in fact most men have no symptoms. A prescription drug called Metronidazole will cure Trichomoniasis.

Shigellosis is an infectious disease cause by a group of bacteria called shigella. Most persons who are infected with Shigella develop diarrhea, fever, and stomach cramps starting a day or two after they are exposed to the bacterium. The diarrhea is often bloody. Shigellossis can easily be spread from one person to another through rimming (oral-anal contact) and from oral contact with contaminated skin including skin in the groin area, the testicles and the penis. Shigella can also be spread via fecally contaminated food and water. People with HIV are more likely to have serious complications from Shigella infections. This bacterium can be treated with antibiotics. Very thorough washing of your genitals and hands before and after sex can help prevent it and other infections, as well as using a barrier (cut-up condoms, dental dams, or household plastic wrap) for oral-anal sexual activities.

Gonorrhea is a common STD caused by a - bacterium called Neisseria gonorrhea. Gonorrhea is spread through contact with the penis, vagina, mouth, or anus. Ejaculation does not have to occur for gonorrhea to be transmitted. Gonorrhea can also spread from mother to baby during delivery. Although many men with gonorrhea may have no symptoms at all, some men have some signs that appear two to five days after infection. Symptoms include a burning sensation when urinating, or a white, yellow, or green discharge from the penis. Sometimes men with gonorrhea get painful or swollen testicles. Gonorrhea infections are completely curable with antibiotics.
  Genital Herpes
Genital Herpes is a STD caused by the herpes simplex virus (HSV) type 1 (HSV-1) and type 2 (HSV-2). Genital Herpes can be transmitted via direct skin-to-skin contact during oral, anal and vaginal sex. HSV-1 and HSV-2 can be found in and released from the sores that the viruses cause, but they also are released between outbreaks from skin that does not appear to be broken or to have a sore.
  • HSV-1 can cause genital herpes, but more commonly causes infections of the mouth and lips, so called “fever blisters”, HSV-1 is also caused by oral-genital or genital-genital contact with a person who has HSV-1 infection.
  • HSV-2- can be transmitted during sexual contact with someone who has HSV-2. Transmission can occur from an infected partner who does not have a visible sore and may not know that he/she is infected.
  • HSV is different from other common viral infections because once it is introduced into your system; it lives there forever, often with periodic symptoms or without symptoms at all. There is no treatment that can cure herpes, but antiviral medications can shorten and prevent outbreaks during the period of time the person takes the medication. In addition, daily suppressive therapy for symptomatic herpes can reduce transmission to partners.
  Genital HPV Infection
Genital HPV Infection is a STD caused by human papilloma virus (HPV) Over 30 virus are sexually transmitted, and they can infect the genital area of men and women including the skin of the penis, vulva (area outside the vagina), or anus, and the linings of the vagina, cervix, or rectum. It is the virus that causes genital and anal warts, usually appear as soft, moist, pink, or flesh-colored swellings, also sometimes called condyloma. The virus may cause wart-like bumps to form on the penis, in and around the vagina, on the cervix (opening to the uterus), and/or around the rectum. The virus is passed via skin-to-skin contact from one person to another during anal or vaginal sex. Warts caused by HPV are not the same warts commonly found on hands and feet, and one type of wart cannot be passed from one body part (hands and feet) to another (genital area). HPV vaccine is an inactivated (not live) vaccine which protects against 4 major types of HPV.
  Viral Hepatitis
It is the name for the inflammation of the liver caused by several different viruses. The viruses are classified by letters of the alphabet — with types A, B, and C being the most common. Each of these viruses can be transmitted in a number of ways, some sexually.

  Hepatitis A
Hepatitis A is a liver disease caused by the hepatitis A virus. Hepatitis A can affect anyone. HAV is found in the stool (feces) of persons with hepatitis A. HAV is usually spread from person to person by putting something in the mouth (even though it may look clean) that has been contaminated with the stool of a person with hepatitis A.
  Hepatitis B
Hepatitis B is a serious disease caused by a virus that attacks the liver. The virus, which is called hepatitis B virus (HBV), can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. Occurs when blood from an infected person enters the body of a person who is not infected. HBV is spread through having sex with an infected person without using a condom (the efficacy of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission), by sharing drugs, needles, or “works” when “shooting” drugs, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth.

Persons at risk for HBV infection might also be at risk for infection with hepatitis C virus (HCV) or HIV.
  Hepatitis C
Hepatitis C is a disease of the liver caused by the hepatitis C virus (HCV). The disease occurs when blood from an infected person enters the body of a person who is not infected.

HCV is spread through sharing needles or “works” when “shooting” drugs, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth.
