Approximately 8–10% of people will experience an epileptic<unk>  during their lifetime. In adults, the risk of<unk>  recurrence within the five years following a new-onset<unk>  is 35%; the risk rises to 75% in persons who have had a second<unk> . In children, the risk of<unk>  recurrence within the five years following a single unprovoked<unk>  is about 50%; the risk rises to about 80% after two unprovoked<unk> s. In the United States in 2011,<unk> s resulted in an estimated 1.6 million emergency department visits; approximately 400,000 of these visits were for new-onset<unk> s. The exact incidence of epileptic<unk> s in low-income and middle-income countries is unknown, however it probably exceeds that in high-income countries. This may be due to increased risks of traffic accidents, birth injuries, and malaria and other parasitic infections.
