In typhoid fever
the fever will be low grade in early gays and gradually increases as the days pass that's why the fever in typhoid fever is called 'step ladder pattern fever'.

Widal test will be positive for few months to a year even though the infection has ben treated effectively with antibiotics.
Improvements in clinical symptoms like fever, general condition, appetite is important rather than the improvement in widal test.
Continue the antibiotics as advised by your Physician and may requires 10 days to 2 weeks of antibiotic course depending on your symptom improvement.
Take rest, soft and bland diet, and plenty of oral fluids and water to maintain hydration.
If any problem, consult again your doctor.
Repeating Widal test is not required unless your doctor asks.
