Dear Enquirer I am sorry to say you have supplied very scanty information. How do you know you have got infection? How do you know you have got typhoid? I think I should discuss little bit about infection. Infection can be (1)Bacterial (2)Viral (3)Parasitic. To determine the infection the person got to have blood test
. Seeing the blood count your Doctor will know wheather you have got viral bacterial or parasitic infection
. For bacterial infection eg Typhoid fever
you should have blood culture
, for parasitic infection like Malaria you should have special blood test and viral infection your blood should be tested for viral antibodies
. Prior to that your Doctor will take your history, and will give you through clinical examination to make a provisional diagnosis and arrange necessary and appropriate treatment. Kindest regards.
