At a glance
- The Cholera and Other Vibrio Illness Surveillance (COVIS) system is used for reporting U.S. cases of Vibrio infection (cholera and vibriosis).
- Information in COVIS helps CDC track infections and determine patient, food, and environmental risk factors.
Background
CDC initiated COVIS in 1989 in collaboration with the U.S. Food and Drug Administration and four Gulf Coast states (Alabama, Florida, Louisiana, and Texas). CDC maintains COVIS.
What's collected
Health officials report cases of Vibrio infection using the COVIS report form, which captures the following information:
- A description of the person's illness and underlying health conditions
- Recent seafood consumption
- Recent exposure to:
- Bodies of water
- Raw or live seafood or their drippings
- Marine life
- Bodies of water
- Source(s) of implicated seafood
