influenza pandemic

Worldwide viral outbreak

An influenza pandemic is a global outbreak of a new strain of flu virus to which most people lack immunity.

Unlike seasonal flu, which recurs annually with familiar strains, pandemics emerge when a novel virus spreads rapidly across continents: The 1918 influenza pandemic killed tens of millions worldwide.

The term distinguishes widespread, severe outbreaks from localized epidemics.
