A febrile seizure is sometimes called a febrile convulsion. Any illness that causes a high temperature (fever) can cause a febrile seizure. Most occur with common illnesses such as ear infections, tonsillitis, colds, flu and other viral infections. Serious infections, such as pneumonia, kidney infections, meningitis, etc, are much less common causes.
