Hi.
Thanks for your query and an elucidate history.
First of all
Widal tests is done to confirm the diagnosis of
typhoid and not as a test to follow up the results of medicines .
The only way to know whether these medicines are helping you or not are by the Clinical improvements, that yourself, relatives and the Doctor sees.
These are in the form of :
Reduction in
fever or no fever for 2 days at least.
Improved facial appearance.
Gaining of power ,/ reduction in weakness.
Feeling better by you,
Reduction in the size of the
liver and
spleen.
Improvement in the pulse , blood pressure and other parameters .
Do not repeat Widal test as it may remain positive for 6 months even after you have been cured of Typhoid.
Ask your Doctor to give a course of 1 to 3 weeks of course of an antibiotic and supportive treatment.
Use boiled and cooled water and only home-made fresh food.
