What Is STD

Sexually transmitted infections and diseases are bacterial or viral conditions that are transmitted via sexual contact with an infected person or through contact with infected bodily fluids.

Common STDs include:

HPV (human papillomavirus). Some types can cause health problems including genital warts and cervical cancer.

  • Cervical cancera cancer arising from the cervix due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body.
  • Genital warts, which are small growths that can occur in the anal or genital areas, caused by a virus that is spread especially by sexual contact.

HIV/AIDS. Acquired immunodeficiency syndrome (AIDS), a chronic condition caused by the human immunodeficiency virus (HIV), damages the immune system and may lead to life-threatening diseases including cancer.

Herpes. The herpes simplex virus (HSV) is a common cause of infections of the skin and mucous membranes, manifesting as tiny, clear, fluid-filled blisters usually around the mouth or genitals.

Chlamydia. This is a common sexually transmitted bacterial infection that is often asymptomatic for years but that  can lead to other health problems if left untreated, including pelvic inflammatory disease (PID), infection near the testicles (epididymitis), prostate gland infection, infertility, infections in newborns, and reactive arthritis, known as Reiter’s syndrome.  

Trichomoniasis. A common, treatable sexually transmitted infection (STI), this disease is caused by a parasitic protozoa called Trichomonas vaginalis.

Syphilis. This is a chronic bacterial disease that is contracted chiefly by infection during sexual intercourse.

Hepatitis B. This is a severe form of viral hepatitis transmitted in infected blood or during sexual intercourse.
