Prevalences of CMV IgG antibody and CMV shedding in saliva among children as a function of age in months. Prevalences of CMV IgG antibody and CMV shedding in saliva are also shown for the mothers who were screened. Red shading represents antibody results and blue shading represents saliva results. Panel A shows data from children ages 0-3 months; Panel B shows data from children ages 4-47 months; Panel C shows data from mothers. Antibody prevalences of mothers and children are not directly comparable because the children came from an unselected population whereas the mothers were selected for testing only if their children were CMV-seropositive, and therefore the seroprevalence among mothers was higher than would be expected in a general population.
