question: Hi doctor, I am an MBBS student. My mother aged 47 years is suffering of typhoid which is a case of relapse and this is the 12th time. She is having a temperature nearby 102-103 degree Fahrenheit. Three years before, she was given Ceftriaxone IV 2 g twice (BD) and after that she was given Ampicillin 500 mg thrice daily for the treatment of typhoid. Now, after three years she is again detected with typhoid. Kindly suggest me how we should proceed.
