Sexually Transmitted Diseases Guide
STD symptoms, testing and treatment information. Important STD information pictures and STD facts. Sexually transmitted diseases are also known as STDs. These diseases are transmitted via different ways of sexual intercourse between men, women and their sexual partners. These infections are caused by viruses, bacteria and parasites and usually have no or little symptoms and this is one of the reasons that most of them stay untreated for a while. STDs spread through oral sex, vaginal sex and anal sex. Most of the time a person might be unaware that he is infected, spreading the disease to multiple partners who in turn might engage in sexual acts with others and so the infection circle keeps on growing. Most of the time these diseases will be treated by a mixture of antibiotics or medications that will remove the infection from the body.
