Vibriosis (Non-cholera Vibrio spp.)

2017 Case Definition

CSTE Position Statement Number: 16-ID-05

Clinical Criteria

An infection of variable severity characterized by watery diarrhea, primary septicemia, or wound infection. Asymptomatic infections may occur, and the organism may cause extra-intestinal infection.

Laboratory Criteria

Supportive laboratory evidence: Detection of a species of the family Vibrionaceae (other than toxigenic Vibrio cholerae O1 or O139, which are reportable as cholera) from a clinical specimen, using a non-cultured based method such as PCR.

Confirmatory laboratory evidence: Isolation of a species of the family Vibrionaceae (other than toxigenic Vibrio cholerae O1 or O139, which are reportable as cholera) from a clinical specimen, i.e., cultured.

Epidemiologic Linkage

A clinically compatible case that 1) has had contact with a case that meets the supportive or confirmatory laboratory criteria OR 2) is a contact of a member of a risk group as identified to be part of an outbreak investigated by ID&O.

Criteria to Distinguish a New Case

Must be at least 30 days since previously reported infection in the same individual.

When two or more different species of the family Vibrionaceae are identified (in one or more specimens from the same individual), each should be reported as a separate case.

Case Classification (Narrative)

Confirmed:

a case that meets the confirmatory laboratory criteria.

Probable:

For this disease/condition, Confirmed and Probable case statuses are included in the released case count.

Case Classification Table

N = This criterion is Necessary in conjunction with all other “N” and any “O” criteria in the same column is required to classify a case.

O = At least one of these “O” criteria in each category in the same column (e.g., clinical presentation and laboratory findings)—in conjunction with all other “N” criteria in the same column—is required to classify a case.
