Medical researchers at the University of Michigan School say a woman died of COVID-19 after a coronovirus-double-lung transplant.

The donor was a woman who, doctors said, had a serious brain injury in an automobile accident, a report published American Journal of Transplant.

The donor reportedly showed no signs of COVID-19 and initially tested negative for the virus.

But researchers said the recipient’s health declined three days after receiving the new lungs. The lung specimen tested positive for the novel coronavirus after the recipient’s death, and a surgeon who handled the donor’s lungs became infected with the virus but later recovered.

Because of this case, doctors stated that more personal protective equipment is needed for health care workers involved in organ transplantation as well as more intensive examination of transplant organs for viruses such as COVID-19.

Researchers said the case appears to be isolated, and that unexpected transmission of infection from donor to recipient occurs in less than 1% of transplant recipients.

The American Center for Disease Control and Prevention said in a separate Report good While published in December, there have been some reports of COVID-19 in organ transplant recipients, “it is unclear whether SARS-CoV-2 can be transmitted from organ donors to the recipient and if the transplant recipient is severe. Are you at serious risk of the disease? Coronavirus disease. “

The CDC said in its report that it observed eight possible cases from the Organ Procurement and Transplantation Network (OPTN), which had a donor-derived infection last spring.

However, the CDC concluded that the most likely source of transmission of COVID-19 in those organ transplants was from the healthcare setting.

Viruses are not without precedent in organ transplantation. Researchers at the University of Michigan say that there have been rare cases in which organs have been infected with West Nile virus, H1N1 flu, Ebola and Zika virus.
