2. Vesicles

The elevated red papules of chicken pox soon accumulate fluid and form small yellow blisters or vesicles. The fluid inside the vesicles gradually builds up and presses against the wall of the cyst. The vesicle then ruptures and forms an open sore. The fluid dries up and forms a crust. Due to the intensely itchy nature of those vesicles, children usually want to scratch the vesicles. Keep their nails clean and cut to prevent them from scratching. Scratching will only spread the infection from one part of the body to another.
