Final answer:
Febrile seizures in children are commonly triggered by a rapid fever increase and usually last less than 15 minutes, not typically indicating a serious underlying illness.
Step-by-step explanation:
Febrile seizures in children are typically associated with a rapid increase in body temperature, often due to a common illness like the flu or an ear infection. These seizures typically last less than 15 minutes and occur in children between 6 months and 5 years of age. This condition does not usually indicate a serious underlying illness like meningitis, but rather is linked to the child's developing nervous system and its response to fever.
While most febrile seizures are harmless and do not lead to other health issues, they can be very frightening to witness. It's important to ensure the child is in a safe environment during a seizure and to seek medical attention if a seizure lasts more than 5 minutes or is accompanied by other worrisome symptoms.
