Sexually transmitted infections are illnesses that can spread through sexual contact, including vaginal, oral and anal intercourse. People can reduce the chances of a sexually transmitted infection by using condoms during any sexual contact.

While the term “sexually transmitted disease” refers primarily to pathogenic infections that negatively affect the carrier, “sexually transmitted infection” is a broader term that includes all infections, regardless of their effect or symptoms.

Some common examples of STI’s include gonorrhea, yeast infection, HIV, genital herpes and HPV. However, any disease that is transmitted sexually can be classified as an STI, including influenza and the common cold.
