Hey, those innoculations aren't the end of the story. I was involved with a patient who went swimming in a waterfall pool in Hawaii and came down with leptospirosis. He didn't mention to his primary care provider that he'd had a splenectomy (and the provider documented other surgical history, so not sure why he omitted that, probably just forgot).

His 9 friends didn't get sick. But they had spleens. He ended up intubated in the ICU and became sufficiently well known in certain circles that I have had conversations with doctors involved in his care on both coasts. Which means he was a terribly interesting patient.

You never, ever want to be an interesting patient...
