A 3-year old boy has been hospitalized for E. Coli with severe intestimanl symptoms after swimming in at Lake Wildwood Beach in Nevada County.  Three other kids have also been treated for E. Coli.

The health deparment closed down the beach after the water test results showed it had the high levels of fecal colforms - bacteria that can cause serious illness:

“Real upset stomach, digestive issues, blood in his stool,” aunt Sara Dunn said. “Was taken to Sierra Nevada Tuesday, admitted to ICU shortly afterwards and was transferred to UC Davis yesterday because he tested positive for E. coli, and it’s now affecting his kidneys.”

From the CDC:

Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract. The types of E. coli that can cause diarrhea can be transmitted through contaminated water or food, or through contact with animals or persons.

E. coli consists of a diverse group of bacteria. Pathogenic E. coli strains are categorized into pathotypes. Six pathotypes are associated with diarrhea and collectively are referred to as diarrheagenic E. coli.
