Sexually Transmitted Infections (STIs)

Sexually Transmitted Infections (STIs) are spread through sexual contact (oral, vaginal or anal sex). Many STIs are easily treated, but if left untreated some STIs can cause serious illness, or even permanent damage such as infertility. If you're sexually active, you should get tested for STIs with each new sexual partner.

Chlamydia HIV/AIDS
Gonorrhea Human Papilloma Virus (HPV)
Herpes Molluscum Contagiosum
Hepatitis A Pubic Lice
Hepatitis B Syphilis
Hepatitis C Trichomoniasis

STIs can be spread through:

  • semen
  • vaginal fluid
  • blood
  • rectal mucus
  • breast milk
