FIG 1.
Subject C18 spontaneously cleared one HCV infection and then became persistently infected with a second HCV strain. The limit of detection (LOD) of the viral load assay (50 international units [IU]/ml) is indicated by a dashed line. Values below the LOD are set at 25 IU/ml and marked with open circles. The arrow at 1,483 days postinfection indicates the time point at which MAbs were isolated from circulating B cells.
