The document discusses treating violence like a disease by viewing it as an epidemic that clusters, spreads, and is transmitted through exposure, modeling, and social norms. It presents evidence that violence increases after wars and that chronic exposure to community violence is associated with increased perpetration of violence. The Cure Violence model aims to detect and interrupt transmission, change the behavior of highest risk individuals, and change social norms of violence. Evaluations found the Cure Violence model reduced shootings by 20-73% in cities where it was implemented. The model is now being replicated in over 20 cities across 8 countries worldwide.
