How harmful for your health is typhoid fever?

Quite curable. The symptoms can be mild or severe and include increasing high fever, headache, abdominal pain, constipation or diarrhea, rose-colored spots on the trunk and an enlarged spleen and liver. With antibiotic treatment, the death rate is less than 1% so the key is to recognizing it before it possibly becomes deadly. Less than 5% of people become carriers and can pass it on chronically.
