Your mother was right, there is no medical association between the illness and its title. The association comes with the appearance of the blisters, or ‘pox,’ that are trademark of the illness. Can you think of another animal with red blisters all over their bodies? That’s right! Chickens! Chickens are quite the little peckers, pecking at everything from their food to each other, therefore creating similar red, bloody, and scabby blisters, which look like those characteristic of chicken pox. It appears to be just a silly name for a not-so-fun sickness.
