Scarlet Fever Rash The photo shows a scarlet fever rash on the forearm.
The rash first appears as tiny red bumps on the chest and abdomen that may spread all over the body. It looks like a sunburn and feels like a rough piece of sandpaper. It lasts about 2-5 days.
Scarlet fever is a disease caused by the same bacteria that causes strep throat. A person with scarlet fever has a throat that is red and sore, often a fever and swollen glands in the neck, and a scarlet fever rash.
