Some sort of rhythmic and not-too-demanding craft, like stringing beads, might be soothing. With a fever that high, she's probably not up for anything that takes sequential planning or much creativity.

Maybe a tea party? Especially if she's having trouble eating, a tea party with food cut into little tiny bite-sized pieces might be enticing.

Sometimes a pretend game can help channel the pathetic-ness of being sick and make it more bearable. For example, the poor little tragic sick orphaned street child who is then rescued by a princess and given good care. You don't need to play the game intensively as a parent, you can just provide a little plot development when you come through the room as you normally would.
