Contracting a sexually transmitted infection (STI) is possible through any type of sex (oral, anal and vaginal) with a person who carries the STI. The infection can live in the body most often without showing symptoms. Sometimes STI’s are referred to as STDs which means “Sexually Transmitted Disease.” They mean the same thing and the terms are sometimes used interchangeably.Check out this video “STD Prevention Beyond Condoms” from Amaze.orgFor information on how to receive STI and HIV testing, contact your local health department.

Does HIV only effect the LGBTQ community? No! HIV can effect anyone who participates in certain behaviors like unprotected sex or sharing needles for drugs and/or tattoos or piercings. Someone can even be born with HIV or contract HIV through breast milk if their birth mother has HIV. In the past, HIV was more commonly associated with MSM (men who have sex with men) but with our knowledge now, we know it can effect anyone! Visit the cdc.gov to learn more about this.I heard that there’s a vaccine that protects you against STI’s. Is this true? There are vaccines available for Hepatitis B and HPV. Most people are vaccinated for Hepatitis B when they are infants. There are two vaccines that offer protection against certain strains of HPV. HPV is a viral STI that has many different strains, some of which can cause cancer and genital warts. Cervarex protects against the two most common cancer causing strains, and Guardasil protects against both the cancer causing strains and the genital warts causing strains. Most doctors now recommend that their patients receive an HPV vaccine before becoming sexually active and many schools now require it. If you’re unsure if you’ve been vaccinated for Hepatitis B or HPV, talk to your doctor about your medical history.Additional Resources: Want to learn in more detail about STIs? Click here!
