3-year-old Colo. boy dies of E. coli

DENVER, Sept. 23 (UPI) -- Health officials in Colorado are investigating the death of a 3-year-old boy who contracted E. coli poisoning.

The source of the bacteria, as well as the strain of the virus that infected the Arapahoe County child, have not yet been determined, the Denver Post reported Tuesday.

The child attended a private in-home day-care center. A Tri-County Health Department official said it is possible for feces contaminated with E. coli to be spread in a day-care center where there's diapering.
