Description
A viral exanthem is a generalized red rash caused by a viral infection. They are most common in children, especially those that have not been vaccinated against measles, rubella and chicken pox. Many infections result in viral exanthems such as adenovirus infections, mononucleosis, measles, German measles, fifths disease and chicken pox. Viral exanthems usually resolve within two weeks without specific treatment.
Symptoms
The rash related to chicken pox can be itchy. But most other viral exanthems just cause spots on the skin. Symptoms are related to the viral infection, and usually limited to fever and sore throat. Younger children may refuse to eat or drink. As a result, they may become dehydrated.
