The spots normally appear in clusters and tend to be:
However, the spots can be anywhere on the body, even inside the ears and mouth, on the palms of the hands, soles of the feet and inside the nappy area.
Although the rash starts as small, itchy red spots, these develop a blister on top and become intensely itchy after about 12-14 hours.
After a day or two, the fluid in the blisters gets cloudy and they begin to dry out and crust over.
After 1 to 2 weeks, the crusting skin will fall off naturally.
New spots can keep appearing in waves for 3 to 5 days after the rash begins. Therefore, different clusters of spots may be at different stages of blistering or drying out.
