High-Risk Groups for E. coli Infection: Children, Pregnant Women, Immunocompromised, and Elderly

Groups at increased risk for severe E. coli illness:

• Young children (<5 years) – Immature immune systems.
• Pregnant women – Physiologic immune modulation.
• Immunocompromised – HIV/AIDS, cancer, diabetes, immunosuppressive therapy.
• Older adults – Age-related immune decline.

These populations should practice strict food safety and seek early care for diarrheal illness.
