Sexual Transmitted Diseases or venereal disease refers only to infections that are causing symptoms. STDs are transmitted through vaginal intercourse, oral sex, and anal sex. STDs can also be transmitted via the use of IV drug needles, childbirth or breastfeeding.Public health authorities estimate that some 10 million cases of STDs occurs annually in The United States, 85 % of these in 15 to 30 year old and almost 65% of all STD infections affect people under the age of 25 Many STDs can be transmitted without sexual contact, although this is not common.

For example, scabies or crab lice may be acquired by sleeping in contaminated bedsheets or by engaging in sexual foreplay; syphilis may be transmitted by  skin to skin contact if the chancre ( the primary lesion) is present. A lab technician working with STDs can become accidentally infected through a skin  cut, and thousands of babies are born yearly with an STD. Other factors, such as emotional tension, drug use. Or pregnancy, can also trigger a genital infection. Herpes infection are found in celibates.
