Viral load and cellular infection levels before and after initiation of ART. (A) Viral load values were calculated before (-) and after (+) initiation of ART and are plotted on logarithmic scale. The median decline in copy number is inserted within the graph. (B) The number of HIV-1 gag copies per 105 cells of the respective cell subset is depicted on the y-axis in logarithmic scale. An occasional subset was not included due to a large difference between the duplicate measurements.
