A fever and a rash may be symptoms of many childhood illnesses, such as scarlet fever, chickenpox, and measles. Most of these illnesses are easily identified by the rash pattern and other symptoms present.

A fever with skin problems may mean a more serious illness is present. Serious skin symptoms may include:

• New, tiny purple or red spots (petechiae).
• Recent onset of bruises (purpura) without having an injury.
• A skin infection (cellulitis).

A child who has a fever and any new skin problems needs immediate medical evaluation.
