Rubella would be bad because of the impact on expectant mothers (Urania anyone). Maybe chicken pox or mumps or regular measles (I had those at nineteen--talk about embarrassing).

I suggested chicken pox because cards would have associations with Lindsey's demise from the same disease.

You know, we don't take "childhood" diseases seriously, but kids die from them. Anyway.

The entire Deck could come down with Mono. ;D
