  A rash is often the first sign of chickenpox in children. Adults may feel tired and have a fever 1 to 2 days before getting a rash. The rash appears as red or discolored raised spots that can turn into itchy, fluid-filled blisters. Fluid may drain from the blisters before they dry and scab over. Not all cases of chickenpox will have blisters. Some cases may only have a mild rash that does not turn into blisters. […] Most vaccinated people will not get chickenpox. If a vaccinated person does get chickenpox, it is usually mild, with few blisters, and low or no fever. The chickenpox vaccine prevents almost all cases of severe disease. […] A person can spread chickenpox to others 1 to 2 days before the rash appears until all blisters are dry and have a scab. It takes about 4 to 7 days after the rash starts for blisters to dry. […] People who were vaccinated and still develop chickenpox tend to have fewer spots and the spots may not contain any fluid. A person with these types of spots is contagious until spots have faded, and no new spots have developed within a 24-hour period.

Small blisters called vesicles begin to appear on the face and scalp, spreading to the chest, back and abdomen and eventually to the arms and legs. After three or four days, the vesicles dry with a granular scab and are usually followed by further crops.

The chickenpox rash can be intensely itchy and distressing, affecting sleep, school and work and can cause scarring of the skin.
