What is "Strawberry Tongue" and is it a sure sign of Scarlet Fever?

I've read about the white coating that peels to reveal a red, bumpy "strawberry" tongue. How common is this symptom? Can other illnesses cause something similar, or is it a definitive indicator for Scarlet Fever?

The “strawberry tongue”—where a white coating peels to reveal a red, bumpy surface—is a classic sign of Scarlet Fever, but it’s not present in every case. Studies suggest it appears in about half of affected children, usually a few days after the rash and fever start. Other illnesses, such as Kawasaki disease, toxic shock syndrome, or even some viral infections, can sometimes cause a red or bumpy tongue, so while a strawberry tongue is highly suggestive, it is not definitive on its own. Doctors consider it alongside fever, rash, and throat symptoms to make an accurate diagnosis.

The “strawberry tongue” is a notable feature of scarlet fever, where the tongue starts with a white coating that later peels to reveal red, swollen, bumpy areas. It is fairly common but does not appear in every case. While other illnesses, such as Kawasaki disease or certain viral infections, can cause a similar tongue appearance, seeing it alongside fever, sore throat, and the typical sandpaper rash makes scarlet fever much more likely. Thus, it is an important clue but not a 100% definitive sign on its own.
