Viral exanthem, also known as non-specific viral rash, is a rash caused by a viral infection. Many viruses can cause a similar-appearing rash, so it is difficult to tell which one is the culprit. Your age, duration of illness, and other symptoms may suggest which virus is the cause. Respiratory and stomach gastrointestinal viruses are common causes of such a rash. Viral exanthem is common in children and young adults who are not yet immune to a number of common viral infections.

Handwashing may prevent spread, and those infected should not go to work, daycare or school. HFMD occurs in all areas of the world. Common constitutional signs and symptoms of the HFMD include fever, nausea, vomiting, feeling tired , generalized discomfort , loss of appetite , and irritability in infants and toddlers. Skin lesions frequently develop in the form of a rash of flat discolored spots and bumps which may be followed by vesicular sores with blisters on palms of the hands, soles of the feet, buttocks, and sometimes on the lips.
