When is one to be febrile?

Answer 1

It depends on how you are using the term. The terms febrile means to have a fever or to be excited.

There is also a febrile seizure, and that is a type of seizure where the person's body temperature rises. It seems that upper respiratory infections or viruses precipitate those. So you would have to be sick or recovering from a recent illness to have this type of seizure. If you mean age, then you'd most likely be from six months to age six, and boys are twice as likely to suffer this than girls.
