Major Sexually Transmitted Infections: Some Basics

If left untreated, the sexually transmitted infections (STIs) described in the diagram below may lead to serious reproductive and other health problems, or even, as with HIV/AIDS and syphilis, to death. STIs can be avoided by consistently using condoms, having sex monogamously with an uninfected partner, or abstaining from sex—oral, anal, and genital.

Your answer may reference the fact that fully developed women have more vaginal secretions, which offer some protection against STIs, than do adolescent girls. Or, you might say that teens are less likely to notify their partners of or seek treatment for an STI until the symptoms become painful. Or, your answer may be more speculative: For example, you might suggest that sexually active teens are more careful about avoiding conception than protecting themselves from STIs.
