Infection with a virus.
It results from a depressed or absent immune response.
Congenital immunodeficiency is present at the time of birth, and is the result of genetic defects. These immunodeficiency disorders are also called primary immunodeficiencies.
People with an immunodeficiency disorder tend to become infected by organisms that do not usually cause disease in healthy persons. The major symptoms of most immunodeficiency disorders are repeated infections that heal slowly.
There is no cure for immunodeficiency disorders. Therapy is aimed at controlling infections and, for some disorders, replacing defective or absent components.
Severe combined immunodeficiency (SCID) is the most serious human immunodeficiency disorder(s). It is a group of congenital disorders in which both the humoral part of the patient's immune system and the cells involved in immune responses fail.
Examples of Immunodeficiency disorders (IMDC) include common variable immunodeficiency (CVID), Severe Combined Immunodeficiency (SCID), and Wiskott-Aldrich syndrome. These disorders affect the body's ability to fight off infections due to a compromised or absent immune system. Treatment often involves strategies to prevent infections and boost the immune system.
The main cause of immune system disorder is expose of closed self antigens those were not recognised by body immune system's antibodies against these self antigens started to produced that combined with it and causes inflammations
