Medical experts say a 6-year-old boy may have gotten a life-threatening disease while he was playing in flood waters.

Doctors at the University of Wisconsin Hospital say the boy started vomiting three days after playing in a flooded creek near his home in Richland Center. Doctors believe the boy has a hard to detect strain of the E. coli bacteria. The child has been on dialysis and in intensive care since Sunday with the kidney disease.

It's the first known health problem linked to widespread flooding in Wisconsin earlier this month.
