Vibrio Infection (all species)


Vibrio are a species of bacteria that cause watery diarrhea and abdominal cramps. They are commonly found in coastal marine waters and, therefore, in filter-feeding shellfish such as oysters (which, for this reason, are best eaten fully cooked).

Infection with Vibrio species is especially dangerous when someone has a compromised immune system or liver disease. Vibrio can also cause severe wound infections. Non-cholera vibrio species include V. parahaemolyticus, V. vulnificus, and others. Also see: Cholera.

Disease Reporting

Health care providers and clinical laboratories are required to report cases and suspect cases of any species of Vibrio to local health departments within 24 hours of identification. Call 971-673-1111 to reach the state health department doctor on call. Cases are subject to restriction on school and day-care attendance, food handling, and patient care for the duration of any diarrhea and/or vomiting.

See our disease reporting page for information on how to report and for telephone numbers of local health departments.
