Viral rash

Viral rash

A viral rash (viral exanthem) is a rash that is caused by an infection with a virus. It may appear as small bumps, blisters or red patches on the body. The rash goes away once the infection has run its course. Although the rash itself is not usually a cause for concern, the underlying virus may require medical care.
