Thank you for using healthcaremagic.
Most important for speedy recovery is correct treatment ( with specific antibiotics after laboratory confirmation of S.Typhi) and supportive measures : adequate hydration, appropriate nutrition, antipyretics to control fever
. You must know that in many cases ( 10%- 20 % ) may appear second relapse with symptoms and signs similar with initial clinical syndrome. If symptoms persisting then antibiotic must be given for a minimum 10 days up to 14 days. However , I would recommend follow up with you physician to rule out any complications and check if prescribed antibiotic has effect.
Good luck .
