Answer

Although shigellosis-related mortality is rare in developed countries, S dysenteriae infection is associated with substantial morbidity and mortality rates in the developing world.

Case fatality is as high as 15% among patients with S dysenteriae type 1 who require hospitalization; this rate is increased by delayed arrival and treatment with ineffective antibiotics. Infants, non-breastfed children, children recovering from measles, malnourished children, and adults older than 50 years have a more severe illness and a greater risk of death

The overall mortality rate in developed countries is less than 1%.

In the Far East and Middle East, the mortality rates for S dysenteriae infections may be as high as 20-25%.
