Most are harmless and live naturally in the intestines of humans and other mammals without causing illness. But, there are a few strains that cause serious illness in humans when we eat or drink contaminated food or water.
Typical symptoms of E. coli infection are stomach pain and diarrhea. E. coli can also cause urinary tract infections (UTIs).
UTIs are common in children and women. By the age of five, 8% of girls and 1-2% of boys have had at least one UTI.
Women and girls tend to get UTIs more often than men and boys for two reasons:

Most often, UTIs are caused by E. coli that get into the urinary tract from stool left on the skin around the anus after a bowel movement. Bleh.
However, some UTIs result from eating E. coli-contaminated food.
To avoid infection and the spread of E. coli, CDC suggests:
No guarantees, but a little prevention might save you or your kids from lots of discomfort.
