Final answer:
Febrile seizures are brief, generally lasting under 15 minutes and do not occur again within a 24-hour timeframe. They are typically connected to high fevers which could result from various infections, including relapsing fevers and certain gastrointestinal problems.
Step-by-step explanation:
Febrile seizures are short seizures that can happen in young children with high fevers. They are characterized by being brief, typically lasting less than 15 minutes, and do not reoccur within a 24-hour period. The fever can be triggered by various infections, such as those causing relapsing fevers or gastrointestinal symptoms. Relapsing fevers, associated with louse- or tickborne infections, present with high fever and may repeat in cycles due to the pathogen's ability to evade the immune system. On the other hand, gastrointestinal issues like sudden diarrhea and stomach cramps usually resolve within a day and seldom involve fever or vomiting.
