Any type of sexual contact that has an infection that can be passed from one person to another is termed as a sexually transmitted disease. It is important to note that sexual contact would not only mean sexual intercourse through the anus or the vagina. It also covers the sharing of sex toys, kissing, and genital-oral contact. STDs are not modern diseases but has been around for years. It was only in 1984 that HIV/AIDS was recognized.

Most STDs are curable but some are not treatable at all such as the viral infections of hepatitis B and C, HPV, and the dreaded HIV. Gonorrhea, used to be a highly treatable STD, has evolved some strains that have become resistant to older created antibiotics. This is the reason why awareness and knowledge about STDS can be the best prevention against the infection.
