Well, in a fanfiction where Ash has a fever, it could lead to a lot of different plot developments. Maybe Team Rocket would take advantage of his weakened state and try to steal his Pokémon. But of course, his friends, like Misty and Brock, would be there to protect him. They might search for a special herb or medicine in the Pokémon world to cure his fever.
One common scenario is that Ash is too sick to continue his journey, so his Pokémon have to fend for themselves and protect him. Another could be that a local Pokémon doctor or healer is sought to cure Ash. Maybe some friendly Pokémon in the area offer their help as well.
In many fanfictions with such a plot, it often leads to a significant shift in Ash's character. He might become more determined and solemn, feeling a great sense of guilt and obligation. Ash could vow to honor Gary's sacrifice by becoming an even better Pokemon trainer. The Pokemon that Gary had might also be affected, some could potentially join Ash's team out of loyalty to Gary or a sense of shared purpose. The story might also explore the reactions of other characters like Misty and Brock, who would be deeply saddened and at the same time in awe of Gary's selfless act.
