Background Information

STIs are contracted by having close sexual contact with someone who is already infected. Some STIs can be treated and cured with antibiotic medicine whereas others cannot. Many symptoms of incurable STIs can be treated to make them easier to live with. There are over 25 different STIs.

Anyone can contract an STI. Most people who contract an STI do not know that the person they have sexual contact with is infected. When discussing sexual health with students, it is important everyone feels comfortable, safe, and heard. Ideas for ground rules are available in the Teacher Guidance for the Key Stage 4 pack.

In this lesson plan, students explore how quickly sexually transmitted infections can spread between people and how to prevent this through the use of condoms. They are introduced to some common misconceptions around STIs and encouraged to identify legitimate sources of information to address these. In addition, the lesson plan includes activities to support students in discussing and negotiating safer sex practices.
