Dr. John Lambert:

I think there is. It could be that people who have pre-existing autoimmune diseases, immunological conditions or things that have not previously been diagnosed are predisposed to it. Perfectly healthy people can catch long Covid, but there are certain predispositions to it. They have not been well worked out but there is probably some kind of immune predisposition. For example, with Covid, we must ask why it is that some 45-year-olds get a cold and others end up with lungs whited out. It is an immunological response of the body to the Covid infection, both in the acute setting and chronically.
