When these symptoms are mild, you have no cause for worry and can wait out the seven to ten days period at home. However, if the symptoms are severe, do not recede after ten days, or if your child is less than six months old, you must consult a physician. Very rarely, complications may arise from your child having HFMD. Loss of fluids is possible if the child is not drinking enough water due to pain while swallowing. Viral meningitis, encephalitis, and paralysis can also occur.

Pregnant women are advised to meet with their doctors if exposed to someone infected with the disease. While the probability of any complication arising is very low, it is best to err on the side of caution.
