Estimated likelihood that detection of Shiga toxin (in absence of genotype information) reflects high-risk STEC infection

Is stool bloody?	Is E. coli O157:H7 excluded?	Estimated likelihood of high-risk STEC
Yes	No	87%
No	No	42%
Yes	Yes	40%
No	Yes	20%

These estimates are based on data from stool testing among 72 children with diarrhea positive for STEC^[1]. The likelihood of high-risk STEC (defined as ability to produce Shiga toxin 2) was calculated based on presence or absence of bloody diarrhea and whether E. coli O157:H7 was excluded.

E.coli: Escherichia coli; STEC: Shiga toxin-producing Escherichia coli.
