The prescription you have sent is of May 2019 and the date of Widal test report is not seen. If her Widal test report is positive repeatedly, it does not necessarily mean that she is always suffering from typhoid. Once someone’s Widal test report comes positive, it can be positive again during an unrelated infection. Otherwise she might be suffering from drug resistant typhoid.
