It is important to remember that STDs may have no symptoms. However, new vaginal or urethral discharge or a new rash after sexual contact should be evaluated by a medical professional.
When symptoms do occur, they can include the following:
Chlamydia Symptoms of chlamydia can include vaginal discharge in women, penile discharge in men, and burning during urination in men and women.
Gonorrhea Gonorrhea can cause thick, cloudy, or bloody discharge from the vagina or urethra, and pain or burning when peeing. If you have gonorrhea in your anus, it may cause itching in and around the anus, discharge from the anus, and pain when defecating. Gonorrhea in the throat may cause a sore throat.
Hepatitis B Acute hepatitis B can cause fever, fatigue, loss of appetite, nausea or vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain, and jaundice (yellowing of the skin and whites of the eyes). Symptoms can appear anywhere from six weeks to six months following exposure to the hepatitis B virus. Chronic hepatitis B sometimes causes symptoms similar to acute disease.
Genital Herpes Signs of genital herpes typically include red bumps that develop into blisterlike sores in the genital area and sometimes on the buttocks or thighs. A new infection with HSV-2 — the virus that causes most cases of genital herpes — may also cause flulike symptoms, including fever, headache, feeling tired and achy, and swollen glands.
Oral Herpes Symptoms of oral herpes can include itching of the mouth or lips, sores or blisters on the lips or inside the mouth, and flulike symptoms such as fever, headache, body aches, and swollen glands.
HIV Early symptoms of HIV infection can resemble those of the flu: fever, headache, muscle aches, and sore throat. They may also include swollen lymph nodes, diarrhea, nausea and vomiting, a fungal infection of the mouth, and a rash on the abdomen, arms, legs, or face. If HIV goes untreated, later symptoms can include fatigue, weight loss, night sweats, joint pain, short-term memory loss, and recurrent infections.
HPV Most strains of HPV cause no symptoms and are detected only after abnormal cells are discovered during a Pap smear. However, some types of HPV cause genital warts, which appear as skin-colored or whitish growths on the genitals or anus.
Molluscum Contagiosum Often the only sign of this skin disease is pink or flesh-colored bumps with a dimple (indentation) in the center. It is most common in children, who typically get it from skin-to-skin contact or from shared towels or similar items. In adults, it can be sexually transmitted.
