Avg H Score is average hepatic histopathology score on a scale from 0, no lesions to 3 severe lesions. DPC is days post challenge. IHC is the Liver RVFV IHC for viral antigen result. H Other Organs is histopathology in organs other than the liver. IHC + lists organs that were positive for viral antigen. Key: + = positive for viral antigen by IHC, − = negative for viral antigen on IHC, s = spleen, k = kidney, ln = lymph node, lu = lung, a = adrenal and i = intestine.
