The Health District hopes to soon know more about how a young Yakima county child got sick from E. coli, according to KAPP TV.

There have been two reported cases in recent weeks; both involve children under the age of 5. Both are in stable condition. Experts say at least one came in contact with farm animals but are still not sure what caused the other.

Health officials say E. coli typically causes diarrhea and upset stomach. It usually passes within a couple of days. Other cases can be more severe, especially in young children or seniors, who tend to have weaker immune systems, where it can develop into hemolytic uremic syndrome, a potentially fatal kidney complication.

The key is to catch it early. Prevention can be as simple as washing your hands regularly to help reduce the risk of exposure.
