Human Parvovirus 4 Viremia in Young Children, Ghana
Figure

Figure. . Parvovirus 4 DNA loads in virus-positive plasma specimens from children compared with those in whole blood samples previously tested (7), Ghana. Virus concentrations are given on a log scale on the y-axis. Each dot represents 1 specimen. Horizontal lines represent median values for each sample group. Children whose plasma was tested had a median age of 15 months, and children whose whole blood was tested had a median age of either 15 or 24 months. Viral load data (i. e., median viral load and range) for the 2 groups of whole blood samples have been reported (7) and were included for comparison with plasma data from this study.
