A 77 year old woman died last week north of where I live in Florida from a bacterial infection called vibrio vulnificus that she got walking in the water after tripping on shells and getting a cut on her knee. Yesterday news reported a man in Galveston TX got the same infection from beach water in Corpus Christi. Vibrio vulnificus is commonly known as "flesh eating bacteria" and becoming more common. Not paranoia if it's true, but I wish it wasn't true.
Also do not eat shellfish from warm bodies of water, they can contain the same bacteria.
The rise of vibrio in the Gulf is because of pollution and climate change. The ecology that normally keeps vibrio in check has been destroyed by human activities and then the waters are warming. I think in the future we are going to see a lot more incurable infections, and it's all because humanity couldn't stop polluting the planet. Sad, really.
A lot of the U.S. population is subclinical immune compromised because of the obesity epidemic and how stressful life has become. People eat poorly, don't exercise, and are stressed to the max. We are ripe for an epidemic.
