Anecdotal, but about 30ish years ago (decades before ME/CFS hit me, & I'd basically never heard much, if anything about it at all), I met a woman at a bus stop in San Francisco, & we got talking while waiting for the bus. She'd been a flight attendant for years, but on disability then. She said she was on this one plane trip & felt fine, but by the time it landed, she knew something was wrong with her. She said she was convinced she caught ME on that plane. She was adamant about the air on that plane not being right. She was still searching for answers as to how she "caught" it. It was such a jarring conversation with a stranger, & at the time I thought, jeez, that's scary. Watch out for that....
Another story was a piece of nonfiction, a short story I read long ago, again before I got sick. Written by a woman, she was on a road trip? Or something, with friends. Alright, just googled it: "A Sudden Illness" by Laura Hillenbrand. That stuck in my memory too. It's online if anyone wants to read it. The New Yorker.
Of course there was Incline Village, & a fairly recent-- again New Yorker article-- about it. I hope this post was helpful to your question.
