An exanthem (from Greek "exanthema", a breaking out[1]) is a widespread rash usually occurring in children. Exanthems can be caused by toxins or drugs, microorganisms, or can result from autoimmune disease.
It can be contrasted with an enanthem.

Historically, six "classical" infectious childhood exanthems have been recognized.[2] Numbers were provided in 1905.[3]
They include:
Scarlet fever is the only rash on this list caused by a bacterium; the others are caused by viruses. Many common viruses such as rhinovirus (the common cold) can also produce an exanthem.
Other exanthematic diseases exist that are not part of the classic list, either because they have only recently been discovered (e.g. unilateral laterothoracic exanthem of childhood) or because they have been found to represent not a single disease, but a general manifestations of various possible viral infections (once called Duke's disease); obviously there are other also other common paediatric infections that do not cause exanthems (e.g. mumps).
Some types of Viral Haemorrhagic Fever are also known to produce a systemic rash of this kind during the progression of the disease. Tick borne illnesses like Rocky Mountain Spotted Fever produce a rash that may become extensive enough so as to be classified as exanthemous in as many as 90% of children with the disease. [6]
Vaccinations now exist against measles, rubella and chickenpox.[7]
