We all know what it's like when there's a bug going around. More than a few people call in sick from work. Every time you cough someone says, "Oh, my sister just had that." When you go to the pharmacy, all of the medicines you need are sold out. In Milwaukee in 1993, it wasn't a bug that was making the rounds, it was a parasite, once which wrecked havoc to the intestinal tracts of those who caught it.
