If typhoid fever is diagnosed in its early stages, a course of antibiotic tablets may be prescribed to you. You will be needed to take these for 7 to 14 days. Your symptoms will start improving within 2 to 3 days of taking medicines. Make sure you rest, drink plenty of fluids and eat regular meals. You should also maintain good personal hygiene, such as regularly washing your hands with soap and warm water, to reduce the risk of spreading the infection to others.
