Euphonious horror

Such pretty sounds, these words. They each conjure a unique and lovely image. Each person might hear them differently, then visualize them differently. But we all agree: these are pretty sounding names for what therefore MUST be pretty lovely places. Yes?

Aurora
Roseburg
Paris
San Bernadino
Sandy Hook
Orlando
Brussels
Charlottesville
Columbine

Now these pretty words are the names of an infection that is spreading in exactly the same way that the hideous threat to humanity when I was a child, the appropriately ugly-sounding Infantile Paralysis. Polio.

So? Where is he? Where is the Jonas Salk to end our current calamity, this latest ongoing and continuing threat to humanity? We need a cure.
As well as a wake-up shot in our collective arm.
