A third of people hospitalised with Covid-19 have "abnormalities" in multiple organs months after getting infected, according to a UK study, potentially shedding light on the elusive condition of long Covid.
Millions worldwide are estimated to suffer from long Covid, in which a range of symptoms such as shortness of breath, fatigue and brain fog last long after patients first contracted the virus.
Yet much about the condition, including exactly how Covid causes such a wide range of symptoms, remains unknown. The authors of the new study, which was published in The Lancet Respiratory Medicine journal, said it marks a "step forward" in helping long Covid sufferers.
The study is the first to look at magnetic resonance imaging (MRI) scans of multiple organs - the brain, heart, liver, kidneys and lungs - after being hospitalised with Covid.
