Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
More specifically, the investigators will examine the speed and extent of spreading of these new health practices after introducing them to three different initial "seed" groups: (1) people chosen on the basis of being named as a friend by many people in their village, (2) people chosen based on being named as a friend by a randomly chosen individual, and (3) a group of randomly chosen individuals. It is hypothesized that spread will occur faster and/or to a greater extent when the intervention is started in groups 1 and 2 versus group 3 (control group).
