1 Ch. 25 Sexually Transmitted Infections & HIV/AIDS Lesson 1 The Risks of STIs

2 Sexually Transmitted Diseases (STDs) Are infectious diseases spread from person to person through sexual contact. A person can have an infection, and pass the infection to others, w/out necessarily having the disease.

3 STDs…The Hidden Epidemic Epidemic- occurrences of diseases in which many people in the same place at the same time are affected. An estimated 65 million people in the US are living with an incurable STD. Many people with STDs are asymptomatic—without symptoms.

4 High-Risk Behavior and STDs In the US teens make up one quarter of the estimated 15 million new cases of STDs each year…that’s more than 10,000 young people infected every day!

5 Teens who are sexually active are likely to engage in one or more of the following high- risk behaviors: Being sexually active with more than one person; most teens are unaware of a partner’s past Engaging in unprotected sex; barrier protection is not 100% effective and is not effective against HPV

6 High-Risk Behavior cont. Selecting high-risk partner’s (those with a history of being sexually active and those who have injected illegal drugs) Using alcohol and other drugs (alcohol lowers inhibitions) in a recent survey, more than 25% of teens who engaged in sexual activity had been under the influence

7 Consequences of STDs Some STDs are incurable (genital herpes, HIV/AIDS) Some STDs cause cancer (Hep B causes cancer of the liver, HPV can cause cancer of the cervix) Can cause complications that affect the ability to reproduce (PID damages reproductive organs & cause sterility) Can be passed on to infants before, during or after birth.

8 Preventing STDs Through Abstinence Sexual activity (oral, anal, vaginal intercourse) is the cause—an STD is the effect Prevent exposure to STDs by practicing abstinence, use refusal skills to avoid situations in which you may be at risk.

9 Abstinence The deliberate decision to avoid harmful behaviors, including sexual activity before marriage and the use of tobacco, alcohol, and other drugs.
