Sexually Transmitted Infections (STI)

Overview of Sexually Transmitted Infections (STIs)

A sexually transmitted infection (STI) is any infection that is passed during sex. STIs can be passed during oral, vaginal and anal intercourse. A few STIs, such as HIV and Hepatitis B, can be transmitted via blood. Others, such as herpes and HPV, can be transmitted via skin-to-skin contact. Symptoms of STIs vary depending on the infection, and some people may show no symptoms whatsoever. It is important to know your risk factors and get tested regularly.

Types of STIs

STIs can be broken down into two main categories: Bacterial infections and viral infections. Bacterial infections can be treated with a course of antibiotics. Viral infections are not curable, but they can be managed with help from a health care provider.

STI Prevention

The risk of acquiring STIs can be greatly reduced by following safer sex practices. These practices include:

  • Correct and consistent condom use. Condoms made from latex, polyurethane, polyisoprene, and nitrile are all effective at preventing STI transmission. Natural skin condoms do not protect against STIs. Condoms are available at SHCS from The Love Lab and Pharmacy.
  • Taking the appropriate steps to avoid condom breakage, such as storing them in a cool, dry place and using water-based lubricants.
  • Using skin-to-skin barrier protection (such as condoms or dental dams) over as much of the genital and/or rectal area as possible during oral, vaginal or anal sex.
  • Having all safer sex products (condoms, dentals, water-based lubricant) on hand before you need them.
    • Latex condoms, non-latex condoms, lubricant and dental dams are available from The Love Lab. Sexual Health Products are also available at the SHCS Pharmacy.
    • The UC Davis Sexcess Map can help you find nearby locations at which to purchase safer sex items.
  • Communicating with your current/potential partner(s). This includes discussing which safer sex products will be used, your current STI testing status, and any history of infection.
