In a globalized world , isn’t the flu a pandemic every year then?
Pretty much, yes. Although CDC has a narrower definition they use specifically for “flu pandemic” to denote a significantly new variant that’s rapidly spreading around the world: https://www.cdc.gov/flu/resource-center/freeresources/graphics/seasonal-vs-pandemic-flu-infographic.htm
But yes, by the basic definition, Influenza virus is a pandemic each year as it’s highly prevalent over a wide geographical area.
