Sexually Transmitted Diseases (STDs) or Sexually Transmitted Infections (STDs) are usually contracted through sexual contact. Organisms causing sexually transmitted diseases can be transmitted from one person to another through blood, semen or vaginal fluids. Sometimes these infections cannot be sexually transmitted, for example from mother to child during pregnancy or childbirth or through blood transfusion or needle exchange.
Mostly these infections do not show symptoms in the early stage of the disease and spread from one to another silently. It is possible to get sexually transmitted diseases from people who appear to be perfectly healthy and may not even be aware of the infection. Sexually transmitted diseases do not always cause symptoms, so experts prefer the term "sexually transmitted infections" to "sexually transmitted diseases". The major symptoms of these infections include abnormal vaginal or penile discharge, ulcers on or around the genitals, and chronic pelvic pain. Some infections are too dangerous that they may cause failure to get pregnant, can pass to the new baby or even can cause death. Some sexually transmitted diseases are listed below
- Genital herpes
- Hepatitis B
- Trichomoniasis (parasitic infection)
- Molluscum contagiosum
- Pelvic inflammatory disease
- Syphilis, gonorrhea
To prevent these sexually transmitted diseases unprotected intercourse with any partner should be avoided.
