In their Keeping Kids Healthy column, UTMB Drs. Sally Robinson and Keith Bly wrote that fewer than 1 in 10,000 children suffer from seizures, and some seizures are relatively harmless, even though they are frightening. Seizures triggered by a fever (febrile seizures) occur in less than 5 percent of children between the ages of 6 months and 5 years. In almost all cases, after a febrile seizure, the child quickly returns to normal.
