A 4-year-old Scott County child remains in critical condition Tuesday morning after being diagnosed with E. coli bacteria. The child is currently in a Lexington hospital.

The father confirmed that the child had a complication called hemolytic uremic syndrome. In the United States, HUS is the principal cause of acute kidney failure in children, reports the Georgetown News-Graphic.

How the child contracted E.coli remains unknown, and presently there have been no efforts to determine how the bacteria were contracted.  Because the exact cause of the Scott County child’s E. coli is unknown and because the child did not eat spinach, it is not believed to be part of the national confirmed spinach case count.
