Key Ideas

  • Sexually transmitted diseases range from minor complaints to life-threatening illnesses. They can be avoided by practicing abstinence, knowing your partner's sexual history, and using condoms with spermicide.
  • Sexually transmitted diseases are caused by bacteria or viruses that are transmitted from person to person through the exchange of bodily fluids, typically through sexual contact.
  • Most bacterial STDs should be treated promptly and completely with antibiotics. Viral STDs are typically more serious than bacterial STDs, are more difficult to treat, and are easier to get in the presence of bacterial STDs.


This section deals with sexually transmitted diseases. It uses a case study to show the impact of STDs on individuals and relationships. Through the characters in the case study, the section describes common symptoms, gives facts about the frequency of STDs, and outlines the important steps in prevention. The first activity in the section asks students to role-play situations in which they become the characters of the case study. In the role, they have to tell the important people in their lives that they have contracted, and may have passed along, an STD. In addition, the section presents the most common bacterial and viral forms of STDs, and indicates the usual treatments where applicable. The section ends with an activity that effectively demonstrates the chain of infection, and how disease spreads from person to person.

\begin{align*}\checkmark\end{align*} distinguish between viral and bacterial STDs.

\begin{align*}\checkmark\end{align*} develop strategies for honest and open communications regarding sex.

\begin{align*}\checkmark\end{align*} recognize that having sexual intercourse with one person also involves being exposed to whatever the previous partners of that person have been exposed to.

\begin{align*}\checkmark\end{align*} recognize that while taking precautions can reduce the risk of infection and cut down on the number of people infected, it does not eliminate all risk.

Advance Preparation

See Activities 6-1 and 6-2 in the student edition.

Activity 6-2: STD Handshake

For Round 1:

  • Count out enough index cards for each student to have one.
  • Mark one index card on the back with an X.

For Round 2:

  • Count out enough index cards for each student to have one.
  • Mark one index card on the back with an X.
  • Mark 2-4 index cards on the back with the letters C+S.
  • Mark one index card on the back with the letters C+S failure.

Interdisciplinary Connections

Language Arts Role-Playing and discussion groups help students develop communication skills, and can lead to essay or journal writing.

Art A Mini Activity involves designing and creating displays.

Science Bacterial and viral transmission of disease are discussed.

Background Information

There are two key issues to get across with respect to becoming infected with an STD-with whom you have sex and what kind of sex is involved. The first is the more important. If your partner is not infected, you will not get infected no matter what you do or how often. A corollary is, the more partners you have, the greater the risk of one of them being infected, hence the greater risk of you becoming infected.

If your partner is infected, then what you do and how often you do it becomes important. This is where safer sex practices must be used. While no practice other than abstinence is foolproof, the use of condoms with spermicide does make a difference, as does what you do (such as being the receptive partner in anal intercourse, which is the highest risk sexual activity).

There are good discussions of STDs in the two sexuality textbooks referred to earlier (Allgeier and Strong).
