One of the major risks of an E. coli O157:H7 infection is the development of a complication known as hemolytic uremic syndrome (HUS), the leading cause of kidney failure among children in the U.S. Approximately 3-15% of children infected with E. coli O157:H7 develop HUS. Of those who develop HUS, there is a 20-30% chance of developing concurrent damage to the central nervous system (CNS, the brain and spinal cord). CNS damage typically accompanies the worst cases of HUS is an indicator for a poor prognosis (1).
Possible symptoms of CNS (brain and spinal cord) damage include (2):
- Seizures
- Altered consciousness
- Behavioral changes
- Double vision
- Dizziness
