Solano County public health officials are investigating the death of a Dixon child from an E. coli infection.  Officials are not releasing a description of the child to protect the victim’s identity.  The source of the infection is unknown, Solano Public Health Education Manager Robin Cox said.  Solano County Environmental Health Services staff surveyed Dixon food establishments but there were no reports of customer or employee illnesses that might be due to E. coli, Cox said.  All area hospitals have been notified to inform the Solano County Public Health Department if they see any patients with symptoms of E. coli. No new cases have been reported, Cox said.  A second juvenile was brought into the emergency room with symptoms of diarrhea but was released and is doing very well at home, Cox said. Stool test results on the second child are pending and there is no indication so far the second minor has E. coli infection, Cox said.
