I don’t know many details but I do know someone personally that has this. She no longer can eat beef I believe and thinks it is caused by a tick bite that occurred a year or two earlier. She lives in the US and does quite a bit of hiking. She would occasionally find a tick on herself and her dog.

Yeah, I know it's a real thing, but it seemed strange that a paper comes out in the US, especially given its nature, and then just days later Swedish media talks about it being a thing with Swedish ticks, something I didn't know. Everything I've heard about the ticks here before has been about TBE and Lyme disease.
