Febrile seizures are the most common seizures of childhood, occurring in 2 to 5 percent of children six months to five years of age.
Approximately one in every 25 children will have at least one febrile seizure, and more than one-third of these children will have additional febrile seizures before they outgrow the tendency to have them.
Febrile seizures usually occur in children between the ages of 6 months and 5 years and are particularly common in toddlers. During a seizure, there is a small chance that the child may be injured by falling or may choke from food or saliva in the mouth. Never place anything in the child’s mouth during a convulsion. Objects placed in the mouth can be broken and obstruct the child’s airway.
There is a 15 to 70 percent risk of recurrence in the first two years after an initial febrile seizure.
