People with CVID have low levels of immunoglobulin (antibodies) and an increased risk for infection. Although the disease is usually diagnosed in adults, it can also occur in children.

CVID is also known by the following names:

  • Hypogammaglobulinemia
  • Adult-onset agammaglobulinemia
  • Late-onset hypogammaglobulinemia
  • Acquired agammaglobulinemia
