Vibriosis (Non-cholera Vibrio spp.)
2007 Case Definition
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.*
Case classification
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.
Probable: A clinically-compatible symptomatic case that is epidemiologically linked to a confirmed case.
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 (COVISS), available at:
http://www.cdc.gov/foodborneoutbreaks/documents/cholera_vibrio_report.pdf.
CDC intends to integrate the COVISS form into the National Electronic Diseases Surveillance System (NEDSS)
in the future. Reporting sites should use the COVISS reporting form until the integration is complete and COVISS 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.
*Infections due to toxigenic Vibrio cholerae O1 or O139 are reportable as cholera (see current
cholera case definition listed below).
