LONDON (Reuters) - A study of the lungs of people who have died from COVID-19 has found persistent and extensive lung damage in most cases and may help doctors understand what is behind a syndrome known as 'long COVID', in which patients suffer ongoing symptoms for months.

Scientists leading the research said they also found some unique characteristics of SARS-CoV-2, the virus that causes COVID-19, which may explain why it is able to inflict such harm.

"The findings indicate that COVID-19 is not simply a disease caused by the death of virus-infected cells, but is likely the consequence of these abnormal cells persisting for long periods inside the lungs," said Mauro Giacca, a professor at King’s College London who co-led the work.

The research team analysed samples of tissue from the lungs, heart, liver and kidneys of 41 patients who died of COVID-19 at Italy's University Hospital of Trieste between February and April 2020.

In a telephone interview, Giacca said that, while his research team found no overt signs of viral infection or prolonged inflammation in other organs, they discovered "really vast destruction of the architecture of the lungs", with healthy tissue "almost completely substituted by scar tissue". ...
