Vibriosis (Non-cholera Vibrio spp.)
2007 Case Definition
CSTE Position Statement Number: 09-ID-69
Clinical description
An infection of variable severity characterized by diarrhea and vomiting, primary septicemia, or wound
infections. Asymptomatic infections may occur, and the organism may cause extraintestinal infections.
Laboratory criteria for diagnosis
Isolation of Vibrio spp. other than toxigenic Vibrio cholerae O1 or O139 from a
clinical specimen.*
Exposure
The most common mode of transmission is via raw or under cooked seafood, with oysters being the most frequently implicated source. Non-cholera Vibrio spp. may also be spread through contact with water, especially seawater.
Case classification
Probable: A clinically-compatible symptomatic case that is epidemiologically linked to a confirmed case.
Confirmed: A case that meets the laboratory criteria for diagnosis. Note that species
identification and, if applicable, serotype designation (i.e., Vibrio cholerae non-O1/non-O139)
should be reported.
Comment
In addition to reporting through the National Notifiable Diseases Surveillance System (NNDSS), CDC
requests that states collect information on the standard surveillance form for Cholera and Other
Vibrio Illness Surveillance System (COVIS), available at:
http://www.cdc.gov/nationalsurveillance/PDFs/CDC5279_COVISvibriosis.pdf.
CDC intends to integrate the COVIS form into the National Electronic Diseases Surveillance System (NEDSS)
in the future. Reporting sites should use the COVIS reporting form until the integration is complete and COVIS data
can be transmitted to CDC. CDC requests that Vibrio cholerae and Vibrio parahaemolyticus
isolates be referred to the Foodborne and Diarrheal Diseases Laboratory for characterization.
The 2007 case definition appearing on this page was re-published in the 2009 CSTE position statement 09-ID-69. Thus, the 2007 and 2010 versions of the case definition are identical.
*Infections due to toxigenic Vibrio cholerae O1 or O139 are reportable as cholera (see current
cholera case definition listed below).
