AIDS determines everyday life in Africa, but is still taboo and shameful in many places. The schools for future university students are located in Tanga. Here, the adolescents are informed about risks and facts and discuss sensible behaviour in group projects. Malaria is also a constant threat in Tanzania. Nevertheless, very few families have access to mosquito nets. The economic conditions are precarious. When a family receives a net from a humanitarian organisation, it is often misused as a fishing net.
