A. Hello mommy, Several common childhood illnesses, including roseola and scarlet fever, can cause a rash to develop after the fever passes. A fever is not a disease but a sign that the body's immune system is fighting an infection. Many children develop fever and a rash (pimples or red patches, or both) at the same time. This could be a sign of infection. Most of these infections are caused by viruses and last a few days.
