Sexually Transmitted Diseases are ailments caused by various kinds of sexual conducts. This may include Vaginal intercourse, Oral sex, kissing of the genitals etc. These diseases may occur due to improper physical hygiene.

Though each STD is unique, many share similar symptoms. They can be painful, irritating, debilitating or, if untreated, fatal. Others may have few identifiable symptoms, and the victims may be unaware that they are infected. Many infected persons resist seeking treatment for their STDs because of ignorance or guilt. Others are reluctant to inform their sex partners that they, too, may be infected because of anxiety and fear that the revelation will damage their reputation or relationship.

This is unfortunate, even tragic, as nearly all STDs can be cured through timely diagnosis and proper medical treatment. Those few for which no immediate or complete cure is known usually can be controlled through medication and preventative measures.

STDs are most common among sexually active teenagers and young adults, particularly those who have multiple sex partners. But no one is immune to STDs. It is important to understand the causes of STDs and the sexual practices that put people at risk of contracting them, their telltale signs and symptoms, the methods of diagnosing and testing for them, and the various ways of treating them. Without this knowledge, the hazards STDs present are greatly increased, and the likelihood of even more widespread infection is multiplied many times over.

The only sure way to prevent a sexually transmitted infection is to limit one's sexual relationship to a single, uninfected partner. Other preventative measures, such as using latex condoms when having sex, may be effective at limiting the risk of infection in certain instances
