Figure 1.
(A) EBV seropositivity rates by age cohorts in a large hospital population (N=16 163). The percentage positivity of IgG antibodies to EBNA-1 and of IgG and IgM antibodies to VCA in different age cohorts is shown. Note that the x-axis is not proportional. EBV seropositivity was defined as seropositivity to at least one of the three antibodies, EBNA-1 IgG, VCA IgG or VCA IgM. The number of persons analysed in each age cohort is indicated above the graph. (B) EBV seropositivity rates by age cohorts in a large hospital population are shown separately for female (n=7714) and male (n=8322) persons. EBV seropositivity was defined as seropositivity to at least one of the three antibodies, EBNA-1 IgG, VCA IgG or VCA IgM. The number of female/male persons analysed in each age cohort is indicated above the graph. EBNA-1, Epstein-Barr nuclear antigen-1; EBV, Epstein-Barr virus; VCA, viral capsid antigen.
