After being exposed to the Salmonella Typhi bacteria, typhoid fever symptoms normally arise gradually, usually one to three weeks later. Abdominal pain, weakness, headache, loss of appetite, and a persistent fever are early indications. A swollen belly, skin rashes, and constipation or diarrhea are other potential symptoms for certain people. If therapy is not received, the sickness may worsen and produce major adverse effects include organ damage or intestine perforation. If you have a persistent fever, substantial stomach discomfort, or any indications of dehydration, you must consult a doctor. A quick recovery could be aided by early diagnosis and antibiotic medication.
