Typhoid fever, with body aches, fever, and weakness, is a bacterial infection that requires proper treatment and rest to recover well. Make sure she takes plenty of fluids, such as water or oral rehydration solutions, to stay hydrated, and give soft, easy-to-digest foods such as khichdi, soup, or boiled vegetables so the body is not strained. Ensure she gets enough rest and avoids heavy activity, and keep her surroundings clean to prevent further infection. A doctor may advise appropriate medications and supportive care based on her condition, which should be followed carefully. Watch for high fever that does not settle, severe weakness, or stomach pain. Consult a doctor for proper treatment and a safe recovery.
