Hello As you had taken the drug of choice i.e. ciprofloxacin for full course for typhoid . Still fever present ,so get in blood for culture and drug sensitivity test . Also get in Widal and serology for confirmation for typhoid . The most important point is that typhoid fever is an intestinal disease ( usually water born ) , so it will take some time for negative outcome in blood slide . However , few strain of typhoid fever ( causative organism ) may be resistant to few drugs , so consult your treating physician and get his opinion and also get his opinion for tuberculosis diagnosis ( because still fever present , so this may be the cause of fever i.e . tuberculosis ). Good luck.
