Paratyphoid fever has three stages: an early stage marked by high fever; a toxic stage with abdominal pain and intestinal symptoms, and a long period of recovery from fever (defervescence).

an early stage marked by high fever

Most patients with paratyphoid fever recover completely, although intestinal complications can result in death. With early treatment, the mortality rate is less than 1%.

Travelers in countries with high rates of paratyphoid fever should be careful to wash hands before eating and to avoid meat, egg, or poultry dishes unless they have been thoroughly cooked.
