Thanks for your question. .. During typhoid you basically need to give your digestive system rest while maintain your body increased metabolic needs.. start with liquid diet with more water ...soups coconut water barley water. .. progress to semi solid then khicdi mashed vegetable bland sabzis.... avoid whole wheat bread oatmeal spicy food cabbage turnips as they cause bloating and gas.... During recovery have more protein. . hope this answers your query fever has typical step ladder pattern....it will gradyally increase and then decrease..With proper antibiotics and tratment it is relatively harmless
