Dear Alok, welcome to HCM.
To diagnose typhoid
we need to demonstrate 4 fold rise in titre.
So would like to have titres of your first Widal test
A week of antibiotic removing the fever
is adequate, provided it was a right antibiotic in right dose.
What did you take ?
You will have some GI upsets. That is Ok, unless you have vomitting, fever, pain in abdomen, weakness etc.
Whatch for any undue distension of the tummy, red spots etc.
Avoid oily, spicy food and alcohol.
Rest , you can eat a well cooked healthy food.
I hope to have answered you well.
Take care anfd good Luck. keep posted.
