There's a similar concept with Lyme Disease. A lot of people who had Lyme claim continuing symptoms, but there's absolutely no evidence for it and there is a lot of contention about the whole thing. With Lyme, it's "Chronic Lyme". Ebola also has post-disease syndrome. I'm sure there are more, but my High School Biology final paper was on whatever we wanted, and I went with Post-Ebola Syndrome, and my college capstone was on Lyme, which you can't write a long ass paper on Lyme without mentioning chronic Lyme, so those are the two I'm somewhat well-versed on. Also, fuck every physician who prescribes basically unlimited antibiotics for shit like chronic Lyme and just the generic over-prescription of antibiotics.
I've known three people with chronic lyme. It's a pigfuck. Has been lo these many decades. One of them responded best to like transfusions and ketamine at which point you are so on beyond zebra with the medical establishment that you might as well try crystals'n'shit for all the assistance you're gonna get.
