#### Lecture and Interactive Discussion (40 minutes)
1. **Definition and Overview:**
- Define STIs.
- Explain how they differ from other infections.
2. **Types of STIs:**
- Present the most common STIs:
- Bacterial Infections (e.g., Chlamydia, Gonorrhea, Syphilis)
- Viral Infections (e.g., HIV/AIDS, Herpes, HPV)
- Parasitic Infections (e.g., Trichomoniasis, Pubic Lice)

3. **Symptoms and Effects:**
- Discuss symptoms associated with each STI type.
- Explain potential long-term health effects if left untreated.
- Distribute handouts with detailed information.
4. **Transmission:**
- Outline methods of transmission (sexual contact, blood transfer, from mother to child during birth, etc.)
- Emphasize the importance of safe sex practices.
5. **Prevention:**
- Discuss various prevention methods (e.g., condom use, regular testing, abstinence, vaccination).
- Use diagrams/charts to illustrate effective prevention techniques.
#### Group Activity (20 minutes)
1. **Case Study Discussion:**
- Divide the class into small groups.
- Each group receives a case study describing a person with symptoms of an STI.
- Groups discuss possible diagnoses, transmission routes, and prevention strategies.
- Each group presents their findings to the class.
#### Question and Answer Session (10 minutes)
- Open the floor to questions from the students.
- Clarify misconceptions and provide additional information as needed.
#### Summary and Homework (10 minutes)
1. **Recap Key Points:**
- Review main points discussed in class: Types, symptoms, transmission, and prevention of STIs.
2. **Homework Assignment:**
- Assign a short research paper on a specific STI of their choice. The paper should cover its causes, symptoms, treatment, and prevention.
- Provide instructions and due date.
#### Closing (5 minutes)
- Thank the students for their participation.
- Remind them of the importance of the topic and encourage respectful and responsible behavior regarding sexual health.
