Acute Communicable Disease Control

The genus Vibrio consists of Gram-negative, curved, motile rods, and contains about a dozen species known to cause human illness. Transmission is most often through ingestion via a foodborne route, but also from contact between broken skin and contaminated water. Presenting symptoms vary by species and mode of transmission. The Vibrio species of greatest public health importance in the US are: V. vulnificus which causes a primary septicemia and is often associated with oysters harvested in the Gulf of Mexico, and V. parahaemolyticus, which presents as gastrointestinal illness. Cholera, a potentially fatal diarrheal disease caused by V. cholerae serotypes O1 and O139, is rarely imported into the US.
