In brief: Other infections
Most high fevers in toddlers are due to viruses.
There are as many different types of viruses as there are types of trees. This time of year could be adenovirus, parvovirus, roseola.....The list goes on. If she is not too sick, it is less likely some other bacteria has got hold of her - things like a blood infection, urinary tract infection, pneumonia. Keep watching child closely and push fluids!
