What causes a viral rash? Viral rashes are caused by either an immune response to the virus or damage to skin cells from the virus. In the case of measles, for example, your immune system detects the virus as it travels through your bloodstream. Immune cells then release chemicals to destroy the virus.
Toddlers and young children often develop viral rashes as their immune system continues developing. Most causes of viral rashes without fever are not serious and resolve within a few days to a week.
