Chickenpox appears as a very itchy rash that spreads from the torso to the neck, face and limbs. Lasting seven to 10 days, the rash progresses from red bumps to fluid-filled blisters (vesicles) that drain and scab over. Vesicles may also appear in the mouth, on the scalp, around the eyes or on the genitals and can be very painful.
This cycle repeats itself in new areas of the body until finally, after about two weeks, all of the sores have healed. The disease is contagious until all the spots have dried up. Unfortunately, the virus is also contagious for at least one day before the rash breaks out.
