Thank you for your query,
The Widal test
titer is high and suggestive of Typhoid fever
Prior typhoid fever will have significant high titers, but in present result the titer is very high and as there is fever it is suggestive of Typhoid fever.
Relapse of fever in Typhoid fever is sometimes present with fever again and requires antibiotics for appropriate duration.
For fever take paracetamol
in prescribed dose, take proper rest and take plenty of oral fluids to maintain hydration.
Consult your Physician for the interpretation of test report and to start specific treatment with antibiotics.
Hope I have answered your query.
