I mean, this is a recurring theme of John Green's "Everything is Tuberculosis"

TB is "just" a bacterial infection. Today, in a wealthy industrialized country with universal healthcare, if I caught TB they'd "just" cure it here. Cures are possible, often even relatively easy.

But all three of the famous Bronte sisters probably died from it (TB == "consumption"), not far from where my mother lives today in that same industrialized country. And most years today it is still the leading cause of infectious disease deaths because even though we could cure it we just leave poor people to die instead.
