We also shared the news of a patient who died two months after receiving the world's first genetically engineered pig heart.



A swine virus was detected in this patient's body.



In January, David Bennett, who was diagnosed with heart disease, received the world's first pig heart transplant.



Bennett lived a normal life without rejection for a while, but his condition suddenly deteriorated and he died in March, two months after the transplant.



The University of Maryland Medical School, which performed the operation, said the cause of death was not known.



It has been reported that the DNA of a pig's cytomegalovirus was found in the heart of Bennett, who died recently.



Cytomegalovirus is a pathogen commonly found in piglets and pregnant sows, causing rhinitis, pneumonia, and fever.



Experts estimate that the hospital tested the pig's heart for the virus before the operation, but did not filter out the virus that was hidden in a dormant state.



Some are concerned that the virus could cause a new type of infection in humans in animal-to-human organ transplantation.
