Sexually transmitted diseases (STDs) are diseases, viruses and parasites transmitted through fluid exchange, or occurring through sexual contact between humans. Other names for STDs include venereal disease (VD) and sexually transmitted infections (STI). The term STI is currently the preferred term as it includes a broader range of diseases, including infections transmitted through the sharing of needles used for intravenously injected drugs. Sexually transmitted infections can be passed from person to person without showing any signs of infection or disease.
Candidiasis (yeast infection)
Hepatitis B virus — saliva, venereal fluids.
Hepatitis A and E are transmitted by fecal-oral routes
HIV (Human Immunodeficiency Virus)— venereal fluids, semen, breast milk, blood
HPV (Human Papilloma Virus)— skin and mucosal contact. 'High risk' types of HPV are known to cause most types of cervical cancer, as well as anal, penile, and vulvar cancer, and genital warts.
