Thanks for the query to H.C.M. Forum.
As you Typhoid fever
is a water born disease.
Once a person become carrier ,it play two roles .
1 Spread disease to others as a carrier.
2 When salmonella
multiply than patient become febrile means he himself get all symptoms.
So consult a physician and get in Widal
once again and take treatment.
If necessary get in blood culture
and drug sensitivity test.
After this get treatment.
Hope I have answered your question.
If further any question I will help.
