What Is Scarlet Fever?
Scarlet fever is an illness that can happen in kids, usually 5–15 years old, who also have strep throat or strep skin infections. The strep bacteria make a toxin (poison) that causes a bright red, bumpy rash.
The rash spreads over most of the body and is what gives scarlet fever (also known as scarlatina) its name. It often looks like a bad sunburn with fine bumps that may feel rough like sandpaper, and it can itch. It usually starts to go away after about 1 week. The skin where the rash was and also the hands and feet might peel for several weeks.
If your child has a rash like this, it's important to call your doctor. Kids with scarlet fever need treatment with antibiotics.
What Are the Signs & Symptoms of Scarlet Fever?
The telltale rash is the main sign of scarlet fever. It usually starts on the neck, face, or chest, then spreads to the trunk, arms, and legs. The face is red, often with a clear area around the mouth. In body creases — especially around the underarms, elbows, and groin — the rash often is a brighter red and forms red streaks.
