Thanks for your query, albeit short and specific.
You have flu and sunning fever for days.
The fever in flu usually lasts for say 3 days.
It is better to consult a Doctor at this point to have clinical evaluation, examination and investigations to see whether there is any other reason for fever to persist for 7 days.
