Hi welcome to health care magic... I can understand your concern.... Your child is typhoid positive and you are given cefixime antibiotic which is good drug to kill causative typhoid bacilli... Complete the course of antibiotic for prescribed 7 to 14 days... Meanwhile take more fruits... Small meal taken with frequent interval.... Semisolid meal is preferred... Heavy spicy excess fried food avoided.. Egg white, boiled chicken like food taken to maintain high calorie Intake... Maintain hydration... After month repeat stool examination to look for residual bacterial infection.. If present than repeat course of antibiotic needed for that.... Take care Advise : Consult physician for examination.... Hope this will help
