After discharge, patients should be monitored for relapse or complications for 3 months after treatment has commenced.

Five percent to 10% of patients treated with antibiotics experience relapse of typhoid fever after initial recovery. Relapses typically occur approximately 1 week after therapy is discontinued, but relapse after 70 days has been reported. In these cases, the blood culture results are again positive, and high serum levels of H, O, and Vi antibodies and rose spots may reappear.
