Hello
You are in panic , first of all be brave , you are
HIV NEGATIVE and this is proved as all three tests are NEGATIVE.
Now about
typhoid fever , please upload latest report of
Widal TEST and also serology test , which confirm that you are having typhoid.
Since , you mentioned that you are having typhoid fever and this is assumed , so I am mentioning the complete treatment for typhoid fever.
Ciprofloxacin 500 mg twice in day for 14 days is the most effective for susceptible organisms.
If resistant ( for ciprofloxacin ) then take CEFTRIZONE 2-3 gm/day 7-14 days ).
Alternatively
Azithromycin1 gm/day orally for 5 days .
This is most accurate and standard treatment for typhoid fever.
So for this consult your doctor and get his opinion.
Good luck.
