Thanks for posting your query.
I understand your concern for your brother.
There are many reasons for the fever. Fever is just the manifestation of underlying disease, which needs to be evaluated.
I don't think you should worry for 10 days old fever, as there are effective treatments available.
I would suggest your brother to get evaluated for the cause of fever. It would include blood tests like complete blood count
, Widal test
for typhoid fever
, peripheral smear for malaria
He can take Tab. Crocin
500 mg whenever required for fever. I would advise him to drink lot of water and proper rest also, as it will speed up recovery.
I hope I have answered your query.
I will be available if you have any followup query.
Wish you and your brother a very good health.
Dr. Jyoti Patil.
