STI ’ s are infections that are spread from person to person through intimate sexual contact. STI ’ s are dangerous because they are easily spread and it is hard to tell just by looking who has an STI. 1 in 4 sexually active teens has an STI ?. 1/12/2013 Dr.T.V.Rao MD 2STDs: STDs STDs are diseases and infections which are capable of being spread from person to person through: sexual intercourse oral-genital contact or in non-sexual ways.

M ore commonly seen in men than women, particularly uncircumcised males Chancroid is spread by having unprotected anal, vaginal or oral sex. Some symptoms include: sores or raised bumps on the genitals which eventually if untreated, becomes filled with pus and eventually ruptures leaving a painful sore/ulcer. The bacterial may also infect the lymph glands in the groin. These glands may become enlarged, hard and painful. In Women, ulcers appear on the genitals, painful urination and painful intercourse Chancroids are contagious as long as the person as open sores. The open sores contain bacteria and any contact with these sores can result in infection. Chancroids may be treated with certain antibiotics. The ulcers generally heal within 2 to 3 weeks. 1/12/2013 Dr.T.V.Rao MD 36PowerPoint Presentation: Chancroid ulcers CDC / Center for Disease Control and Prevention/ Division of STD Prevention 1/12/2013 Dr.T.V.Rao MD 37PowerPoint Presentation: Chancroid Male- Regional adenopathy CDC / Center for Disease Control and Prevention/ Division of STD Prevention 1/12/2013 Dr.T.V.Rao MD 38Chlamydia: Chlamydia Bacterial Infection Spread During unprotected anal, vaginal, or oral sex.

An infected person with no symptoms can still pass the disease to others, or have serious complications. Symptoms in a male may include: a slight discharge (drip) from the penis, and a tingling sensation or pain with urination. A female may experience irregular bleeding, pain during intercourse, a vaginal discharge, belly pain, or pain with urination. Untreated chlamydia can lead to fertility problems.

Scabies mites burrow into the skin producing pimple-like irritations or burrows. Scabies mites are transferred by direct skin-to-skin contact. Indirect transfer from undergarments or bedclothes can occur only if these have been contaminated by infected people immediately beforehand. Scabies can also be transmitted during sexual contact. The most prominent symptom of scabies is intense itching particularly at night. The areas of the skin most affected by scabies include the webs and sides of the fingers, around the wrists, elbows and armpits, waist, thighs, genitalia, nipples, breasts and lower buttocks. Skin lotions are available through a physician's prescription for the treatment of scabies. 1/12/2013 Dr.T.V.Rao MD 102ECTOPARASITIC INFESTATION PEDICULOSIS PUBIS: ECTOPARASITIC INFESTATION PEDICULOSIS PUBIS Humans are the only reservoir for pubic lice Can be transmitted by sexual & close nonsexual contact Pruritus is the most common symptom Rx Washing the area with pediculicide formulations Washing the clothes & linens with very hot water 1/12/2013 Dr.T.V.Rao MD 103PowerPoint Presentation: Scabies (under the skin crabs) 1/12/2013 Dr.T.V.Rao MD 104PowerPoint Presentation: Scabies (under the skin crabs) 1/12/2013 Dr.T.V.Rao MD 105What STD screening tests would you order?: What STD screening tests would you order?
