Yes, to clarify, I doubt infection causes autoimmunity more than very rarely, but I think ME presenting as an infection may be autoimmune. If the effect of the autoimmune response is to make the person react excessively to viruses then the first sign of the auotimmunity will be a 'viral illness'. Something like this happens in lupus. The effect is to make the patient unable to defend themselves against bacterial or fungal infection so the lupus may present as severe sepsis.
very, very interesting. @Jonathan Edwards, you are a fountain of enlightenment. could you elaborate a little more on what happens with the Lupus auto immune response that makes people react excessively to viruses? Does this happen for other types and functions also?
