My guess is they’ve done appropriate investigations into which came first. IMO, there’s a reason they suspected the lungs were the source.Not good at linking, but from the Yahoo (thanks anneg) article:
A surgeon who handled the donor lungs was also infected with the virus and fell ill but later recovered.
Doctor or lung is the source?
From the article:
“Suspicious about the origin of the infection, doctors returned to samples from the transplant donor. A molecular test of a swab from the donor’s nose and throat, taken 48 hours after her lungs were procured, had been negative for SARS-Cov-2. The donor’s family told doctors she had no history of recent travel or Covid-19 symptoms and no known exposure to anyone with the disease.
But doctors had kept a sample of fluid washed from deep within the donor lungs. When they tested that fluid, it was positive for the virus. Four days after the transplant, the surgeon who handled the donor lungs and performed the surgery tested positive, too. Genetic screening revealed that the transplant recipient and the surgeon had been infected by the donor. Ten other members of the transplant team tested negative for the virus.”
