An epidemi logist of the jackson villmao clinic named doctor walter hellinger, began an investigation to try and find out exactly how william ramsey had contracted hepotitus c they must have thought that the heptotos came from his newly transplanted liver or something. Well, they they went looking. They focused very heavily on the liver transplant unit. And what they were looking for was perhaps another patient who had been treated in the liver transplant units had given the os to mister ramsey. But there was no provider to patient transfer. So the new liver was fine.
