Impetigo, a bacterial infection of the skin that can occur in both children and adults, can cause blisters. Chickenpox, an infection caused by a virus, produces itchy spots, and often blisters on the skin. The same virus that causes chickenpox also causes shingles, or herpes zoster. The virus reappears in some people later in life and produces a skin rash with fluid vesicles that can rupture.
Rocephin is part of a class of drugs called cephalosporins. It prevents bacteria's ability to make and maintain their cell wall. Without a cell wall, bacteria are vulnerable and ultimately perish.
