Mysterious polio-like illness affects kids in California

A new virus has popped up in California, striking at least 25 kids with polio-like symptoms (from a paralyzed limb to four paralyzed limbs to respiratory paralysis). It’s not polio, but apparently works just like it.

I have the feeling that the latter half of the 20th century and the first decade or two of the 21st might well be remembered as a golden age between eras of pestilence.
