In brief: Depends...

Fever of unknown origin is typically diagnosed after a fever of 4-6 weeks without any discernable cause; however, the grade of fever is an important characteristic.
Most febrile illnesses last no more than 1-2 weeks; so you should have the child examined by his/her pediatrician to help discern the cause and prescribe treatment.

In brief: Not long

Most viral infections cause fever for 48-72 hours, while bacterial infections can last longer depending on the treatment timing and sensitivity to antibiotics prescribed.
In general, if it's been more than a day or so(in children, not infants) it's time to see the pediatrician
