In brief: Viral? Allergic?

Blotchy appearing reddish rashes can occur when the blood flow in the tiny vessels at the skin's surface change, such as in an allergic rash, a viral rash, or in reaction to changes in skin temperature.
Viral infections that cause cold symptoms and other symptoms can sometimes cause such skin patterns (fifth disease, caused by a virus, can cause reddish patterns). A doctor can evaluate if needed.
