I have experienced the "long-CoVID" back in 2020-21. It was scary, especially when driving, as my sense of time and space were altered enough that I could have been in some serious accidents multiple times. I know of healthcare workers, doctors, nurses, therapists, not being able to work and had to stay at home for extended periods of time. This prolonged brain inflammation is no joke. Eventually, slowly, over several months it fades away, but it sucked not being yourself. People walking up to you,
"Are you OK?" Seriously, people were taking notice.
Is it part of being on the spectrum? Yes and no. No, in the sense that this prolonged brain inflammation can occur in anyone. Yes, in the sense that the immune response in many autistic individuals (myself included) results in an over reaction of inflammatory mediator release, enhancing the inflammatory response.

There have been several cases where CoVID infections have led to tiny blood clots throughout the body, effecting heart, lung, kidney, and brain function.
Being in the medical field, I have a totally different perspective with regards to these CoVID infections. It's not a "cold". It's not "the flu". It's an entirely different thing in terms of what it does to the body.
