We've had several cases resulting in death written up in the local media down here. All seem to be older guys (60+) with open wounds (whatever that means) who were in the water.
CDC reports (https://www.cdc.gov/vibrio/
) about 80,000 cases with about 100 fatalities. 52,000 due to food contamination. The remaining 28,000, due to, presumably, water contact. The distribution of fatalities is not parsed as to food or wound related.
Immuno-compromised individuals are at greatest risk. Brackish water vice fresh or salt water promotes vibrio vulnificus presence. The key seems to be getting medical attention promptly when signs of infection exhibit - although that didn't seem to help the poor guy in Maryland.
At 3:1000 fatality odds after infection, I think I'll continue to eat a dozen raw and go over the side as required or desired.
