Welcome to HCM
You are having some kind of viral fever
as symptoms are of Flu, even dengue is viral fever .
During early stage of fever widal test
is of less use to diagnose Typhoid
if clinically suspected a blood culture
is more appropriate but it other things are all right it could be just viral fever.
You can take rest and treatment as advised by your Physician.
If fever persists or if required a repeat test if rising titre is seen then it is suggestive of typhoid.
A platelet count
to know any effect on these cells may be done .
If you start feeling well and no fever you should recover fast and just take care of your health.
Best of Luck.
