Physicians at a hospital in Taiwan that mistakenly transplanted four patients with HIV-infected organs may face criminal prosecution, an official said Friday. The doctors involved may face up to 10 years in prison if found to have caused patients to contract the HIV virus by negligence, Taipei Prosecutors’ Office spokesman Lin Wen-teh said. Last week, Taipei’s National Taiwan University Hospital performed the transplants of the liver, lungs and two kidneys from a donor it mistakenly believed was HIV negative. Another facility, National Chengkung University Hospital, transplanted the heart into a patient there based on NTUH’s information.
