Most Adults have IgG antibody to EBNA and VCA due to past exposure.
Antibodies to EA do not occur in approximately 10 to 20% of adults and
children with acute IM. Antibodies may be absent in some persons with
latent infections. Immunosuppressed, transplant and immunodeficient
patients often have high levels of antibody to VCA IgG and EA
suggesting reactivation of latent virus. The EBNA IgG antibody
level generally does not rise during a reactivated infection.
