Common Respiratory Viruses
Severe Combined Immunodeficiency (SCID) - Patients commonly develop life-threatening infections with common respiratory viruses such as RSV, Adenovirus, Influenza, and Parainfluenza due to complete absence of T cell function.
Other Serious T Cell Defects
Other serious T cell defects -Patients with other immunodeficiencies that result in impaired T cell function are also at risk for developing severe respiratory virus infections. Examples include 22q11.2 deletion syndrome, MHC Class II Deficiency, ZAP70 deficiency, CD25 deficiency, and Wiskott-Aldrich syndrome.
