When an influenza pandemic emerges, WHO adheres to its six-phase preparedness plan. Phases 1–3 are the early stages in pandemic preparedness designed to prevent or contain small outbreaks. The 4th and 5th phases are characterized by urgency in implementation of mitigation procedures. Phase 6 is characterized by widespread disease and sustained transmission of the virus between humans.
