The donor's corneas were used for grafts for three others. The article states:
> The three patients’ grafts were removed, and one tested positive for rabies, the doctors said. None of the three patients had symptoms of rabies, but they were being treated with preventive drugs, the report said.¶ Since 1978, four organ donors have passed rabies to 13 organ recipients, the report said. Of the 13 recipients, six who received treatment for rabies survived. The seven others, who did not receive treatment, died.
