How does your immune system react after you recover from a viral infection?

What is the pathophysiology of viral autoimmune disease?
Virus-induced autoimmune disease The breaking of tolerance or unresponsiveness to self-antigens, involving the activation of autoreactive lymphocytes, is a critical event leading to autoimmune diseases. The precise mechanisms by which this can occur are mostly unknown.
What is an autoimmune reaction?
An autoimmune reaction is initiated as the immune system begins an attack against these particles believing the host cellular DNA to be of foreign origin. “Here we have a vicious cycle of our immune system attacking our own DNA that causes more and more cell damage leading to tissue damage in major organs.
