FIG. 1.

Patterns of disease and virus excretion in four patients who received IG. Elevations of liver enzyme (alanine amino transferase [ALT]) are indicated by the solid line (measured in international units per liter). Solid circles indicate virus excretion as detected by EIA, while solid diamonds indicate virus excretion as detected by PCR-ETBr. Solid squares depict virus detected by PCR-NA. The arrows for patient 1 indicate the specimens that were used for animal infectivity studies (dates, 27 September and 2 and 9 October). Dates on the x axis are given as month-day.
