My mother is 50 years old. For a week she has been having abdominal discomfort with a little loss of appetite. Her stools have also changed colour to a light brown, almost whitish appearance. Last night, her temperature rose to 100 degrees Farenheit but abated when she took Paracetamol. Recently, someone in our house had typhoid fever. Is it possible she may also have it? What tests do we need to do?
