That E. coli O157:H7 outbreak linked to a Vancouver, Washington day care has taken the life of a child.

It’s a little overwhelming as 16-month-old Sorenne nuzzles next to me while trying to go back to sleep. Usually me typing on the computer or talking on the phone bores her into sleepdom.

“We are deeply saddened by the tragic death of this child,” said Dr. Alan Melnick, Clark County Health Officer. “Our hearts go out to the child’s family during this very difficult time.”

Officials said the seven people who work or attend the center displayed signs of E. coli bacteria but haven’t become seriously ill. So far, investigators haven’t been able to identify the source of the bacteria.

In a statement, the day care providers said Friday they’re grieving and are "still overwhelmed by this tragic loss."
