Answer 1

Answer:

Sexually transmitted diseases (STDs) are infectious diseases that spread from person to person through vaginal, anal and oral sex. They are caused by bacteria, parasites and viruses.

Common STDs include:

HIV: Human immunodeficiency virus, or HIV, attacks the immune system, which is your natural defense against illness. HIV causes AIDS, or acquired immune deficiency syndrome. Early on, there may be no signs or symptoms. If and when a person with HIV becomes sick with associated infections, they are said to have AIDS.

HPV: Human papillomavirus (HPV) is a group of more than 150 related viruses. Each gets its own number, called its HPV type. Many forms of HPV cause warts (papillomas) often found on the inside or outside of the genitals. Genital warts can spread to surrounding skin or to a sexual partner. Some HPV types have no symptoms and vanish without ever causing health problems. However, if the virus lasts, it can lead to abnormal changes in the cells, which can progress to cervical cancer.

Chlamydia: This STD is caused by bacteria called chlamydia trachomatis. Women get the infection in their cervix, rectum or throat. Men can get it in their urethra, rectum or throat. It can cause abnormal genital discharge and burning during urination. In women, chlamydia can lead to pelvic inflammatory disease (an infection in the uterus, ovaries or fallopian tubes), tubal (ectopic) pregnancies and infertility. If passed on to a baby, it can cause eye infections or pneumonia. Chlamydia testing is important because it’s treatable with antibiotics; since it doesn’t always bring symptoms, many people with chlamydia don’t know they have it.

Gonorrhea: Easily treated with antibiotics, this bacterial infection is carried in semen and vaginal fluids. Symptoms include burning, itching, redness and swelling in the vagina or penis as well as frequent urination. Left untreated, it can cause pelvic inflammatory disease, tubal pregnancy and infertility, and joint infection and arthritis (known as disseminated gonococcal infection). Gonorrhea can also be spread during childbirth and cause serious eye infections to babies.
