The Coverscan study aims to assess the long-term impact of Covid-19 on organ health in around 500 “low-risk” individuals – those who are relatively young and without any major underlying health complaints – with ongoing Covid symptoms, through a combination of MRI scans, blood tests, physical measurements and online questionnaires.

Preliminary data from the first 200 patients to undergo screening suggests that almost 70% have impairments in one or more organs, including the heart, lungs, liver and pancreas, four months after their initial illness.

“The good news is that the impairment is mild, but even with a conservative lens, there is some impairment, and in 25% of people it affects two or more organs,” said Amitava Banerjee, a cardiologist and associate professor of clinical data science at University College London.
