What are the common signs and symptoms of scarlet fever?

Scarlet fever is characterized primarily by its hallmark signs, which include a distinctive skin rash and fever. The rash typically appears as a fine, red, sandpaper-like texture that often starts on the neck and then spreads to the trunk and limbs. Accompanying the rash is usually a high fever, which is a sign of the body's immune response to the infection caused by streptococcus bacteria.

While other symptoms can accompany scarlet fever, such as a sore throat, headache, and potentially even nausea, the core signs that define the condition are the skin rash and fever. This dual presentation is what helps healthcare providers to make a prompt diagnosis of scarlet fever, distinguishing it from other illnesses.
