Hand, foot and mouth disease is common in children under 5 years old and spreads quickly. The disease usually goes away on its own and does not affect the child's health too much. However, if children with hand, foot and mouth disease are not cared for properly, it can cause many dangerous complications for the child.

Warning signs of complications of hand, foot and mouth disease are often atypical and easily overlooked. More dangerously, these complications often develop rapidly and can cause death within hours.
