The grandmother of a 4-year-old Oregon girl who died last September after testing positive for an E. coli infection is advocating legislation to require testing of children for the pathogen after four consecutive days of specific symptoms.

House Bill 3540, sponsored by state Rep. David Gomberg (D-Otis), would require Oregon health care workers to screen for pathogenic E. coli bacteria any patient younger than 18 “who presents with four or more consecutive days of unexplained diarrhea.” HB 3540 has been referred to the House Committee On Health Care for further action. Besides diarrhea (often bloody), symptoms of E. coli infection include severe stomach cramps and vomiting. Most people sickened by the bacteria get better within 5-7 days, but others, especially young children, can develop serious and potentially life-threatening complications such as hemolytic uremic syndrome (HUS), which can cause kidney failure, permanent damage and death.
