National case definition: Verotoxigenic Escherichia coli infection
Date of last revision/review: May 2008
Only confirmed cases of disease should be notified.
Type of surveillance
Routine case-by-case notification to the federal level
Laboratory confirmation of infection with or without clinical illness:
- isolation of verotoxin producing E. coli from an appropriate clinical specimen (e.g. feces, urine, blood)
- detection of verotoxin antigen or nucleic acid
Clinical illness in a person who is epidemiologically linked to a confirmed case, which would include persons with hemolytic uremic syndrome (HUS)
Further strain characterization, including phagetyping and molecular typing (e.g. PFGE typing), is indicated for epidemiologic, public health and control purposes.
Clinical illness is characterized by diarrhea (often bloody) and abdominal cramps; fever is often absent. Illness may be complicated by hemolytic uremic syndrome (HUS), thrombocytopenic purpura (TTP) or pulmonary edema. Asymptomatic infections may also occur, and the microorganism may cause extra-intestinal infections.
A04.3 Enterohaemorrhagic Escherichia coli infection (includes VTEC)
008.04 Enterohaemorrhagic Escherichia coli infection (includes VTEC)
VTEC includes non-O157 E. Coli.
Probable case definitions are provided as guidelines to assist with case finding and public health management, and are not for national notification purposes.
