The original acute episode usually lasts a few days, but "repeated waves of inflammation and pustulation may follow."

New vesicle formation typically continues for 3--5 days, followed by lesion pustulation and scabbing.

The taxonomy of the genus is very confusing, as there are many variations of eye placement, pustulation, and spine length.

This prodromal phase was followed 1-10 days later by the development of a papular rash that typically progressed through stages of vesiculation, pustulation, umbilication, and crusting.

The person who looks at the world and sees nothing but pustulation is no better or worse-philosophically speaking-than the person who looks at the world and sees nothing but puppy dogs.
