  • Also because it's kind of hard to tell when someone has fifth disease, other than the rosy cheeks, because they could just be, you know, rosy cheeks, or sunburn, or maybe the kid's overheated or whatever. At least, I couldn't tell when my spawn had it till the doctor told me.

  • No, it's real. Apparently, after naming 4 different kinds of rashes/diseases kids could get, this was the best they could do for number 5. If I'm remembering correctly, a pregnant woman should avoid contact with a child with fifth's disease. Easier said than done if that child happens to be one of hers...
