Bear in mind, another 1918 like flu will come - and even modern medicine is basically helpless to stop it - we just know better how to treat it.
The movie Contagion was partially set where I live in Minnesota - it contained depictions of people assembling for food, vaccines, treatment, and mass burial. Seeing local landmarks in the movie made it feel very real and made me think more about emergency preparedness.
