Thanks for using Healthcaremagic,
Your history of fever
for almost 1 year and with only limited available details it is not possible to exactly point out reason pf fever.
1:40 dilution for widal test
is not significant so your problem may not be Typhoid
You should consult a Physician and after proper history and relevant investigations cause of fever may be detected if at all there is fever which also needs to be recorded properly.
Treatment depends on cause, In such cases we need to investigate for hidden Tuberculosis
, or low grade malignancy or infection like HIV?
Hope this helps.
