What distinctive tongue appearance is associated with scarlet fever?

The distinctive tongue appearance associated with scarlet fever is known as "strawberry tongue." This term describes a tongue that appears red and bumpy, resembling the surface of a strawberry. This characteristic is a result of the inflammation and swelling of the tongue, which is often seen in cases of scarlet fever due to the infection caused by group A Streptococcus bacteria. Along with the red color, the tongue may also have an enlarged appearance and may be covered with a white coating initially before becoming red and smooth as the condition progresses.

The presence of strawberry tongue is an important clinical sign that helps healthcare providers diagnose scarlet fever, particularly when accompanied by other symptoms such as a rash, fever, and sore throat. Recognizing this tongue appearance can assist in differentiating scarlet fever from other similar illnesses.
