What Is a Viral Exanthem Rash?

Viral exanthem rash is a common skin condition characterized by a widespread, red, and itchy rash. It is typically caused by a viral infection, such as measles, rubella, or chickenpox. The rash usually appears within a few days of the onset of other symptoms, such as fever, cough, and sore throat. In most cases, the rash clears up on its own within a few weeks. Treatment is usually focused on relieving the symptoms of the rash, such as itching and discomfort.
