Weird. Pretty much every time I've gone to a doctor (in the Midwest US, no less) for an illness, the second question they ask is always "have you been out of the country recently?" just to rule out anything caught from abroad.

Then again, my one experience with a university hospital was pretty shitty, so maybe that's it?

I came back from Bali and shortly after came down with a really high fever when I was on vacation in Maine. When I got home week later called my primary as I was still running a bit of a fever and got blood work which was pretty bad. Went to ER and my primary care figured it was something tick related. The infectious disease guy on call immediately identified as Dengue Fever. At the end, including sending blood to the Louis Pasteur Institute in Paris I spent something south of $1K to get told I’d recover on my own—the Paris tests came back like weeks later—and there really wasn’t much they could do.

I had a weird cardiac issue, for which they kept me in the hospital for a few days and brought in more and more doctors to hear my story. Added tens of thousands to my bill. Eventually checked myself out "against doctor's advice".
