Causes Of Sexually Transmitted Diseases?

There are three major causes of STDs/STIs:

  • Bacteria, including chlamydia, gonorrhea, and syphilis.
  • Viruses, including HIV/AIDS, herpes simplex virus, human papillomavirus, hepatitis B virus, cytomegalovirus (CMV), and Zika.
  • Parasites, such as trichomonas vaginalis, or insects such as crab lice or scabies mites.

How do you get sexually transmitted diseases?

Many STIs are spread through contact with infected body fluids such as blood, vaginal fluids, or semen. They can also be spread through contact with infected skin or mucous membranes, such as sores in the mouth. You may be exposed to infected body fluids and skin through vaginal, anal or oral sex.

How does the first person get an STD?

At some point – thought to be at least before 1930 – humans ate some chimpanzees infected with the SIV virus which mutated into HIV. It might be difficult to say who was actually the first to catch it; in fact there may have been several simultaneous infections.
