The World Health Organization and INTERPOL announced a cooperation agreement in Geneva and Lyon on October 16, linking public-health expertise with a law-enforcement network spanning 196 member countries. The framework covers unusual biological events, suspected misuse of chemical or radioactive materials and health risks at major international gatherings that require coordinated health and security action. It also targets falsified medicines, vaccines and medical devices, counterfeit protective equipment, fraudulently labelled food and drink and illegally produced alcohol. The two bodies will cooperate against trafficking for organ removal and illegal trade in organs, tissues and cells and support implementation of the tobacco-control convention. The agreement creates a channel for cooperation rather than automatic enforcement authority; results still depend on national reporting, evidence exchange, regulatory capacity and cross-border case execution.
