Typhoid fever, also known simply as typhoid, is a bacterial infection due to a specific type of Salmonella that causes symptoms.[3] Symptoms may vary from mild to severe, and usually begin 6 to 30 days after exposure.[1][2] Often there is a gradual onset of a high fever over several days.[1] This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting.[2][6] Some people develop a skin rash with rose colored spots.[2] In severe cases, people may experience confusion.[6] Without treatment, symptoms may last weeks or months.[2] Diarrhea is uncommon.[6] Other people may carry the bacterium without being affected; however, they are still able to spread the disease to others.[4] Typhoid fever is a type of enteric fever, along with paratyphoid fever.
