Sexually Transmitted Diseases (STDs) or Sexually Transmitted Infections (STIs) are conditions that are passed from one person to another through sexual contact, including during vaginal, anal, and/or oral sex. Symptoms of STDs are varied and, in most of the cases, considerably uncomfortable. Both males and females can be infected with a STI, although they typically have more severe effects on women than in men. The best weapon to fight against STDs is prevention, either by using condoms, or through vaccinations, or any other preventive measure.
Sexually Transmitted Infections are transmitted from one person to another through contact with infected body fluids, including blood, semen, vaginal discharge, etc., hence that the main route of infection is through unprotected sexual contact. However, there exist other ways STIs can be transmitted through, such as needle reuse, blood transfusion, touching someone that is infected, and even from mother to baby while pregnant or during labor. The following are the main causative agents of STDs: Bacteria: gonorrhea, syphilis, chlamydia. Viruses: human papilloma virus (HPV), hepatitis, genital herpes, HIV. Parasites: scabies, trichomoniasis.
