yes, it was long hypothesised but the study proving the viral link was published Jan 22. med.stanford.edu/news/all-new... The paper linked in the original post is showing the mechanical way the virus causes MS. Its not necessary to educate me on this.
The point of my post was not that we didnt know anything abt viruses causing neurological disorders prior to COVID, but rather that in the past 5 years the science behind our understanding of this link has accelerated.
Apologies for the harsh tone of my first reply.
