Imagine this thing that has actually happened: You're in the US when your infant develops a strangely-shaped skin lesion. Seeing this disgusting skin lesion and thinking it might be anthrax, you take your child to the doctor. "Doc, I think I my kid has anthrax," you might say. The doctor's eyes roll. "It's obviously a spider bite," doc probably replies. Turns out your kid had anthrax all along.
