In brief: Impetigo

On the correct antibiotics it should heal quite promptly.
Once it heals, it's not contagious. As long as the blisters are there though, i would consider contagious.

In brief: When it's crusty

Impetigo is contagious until crusty plaque is completely resolved with complete healing (closure) of the skin without residual weeping or discharge.
