A consultant respiratory physician at Beaumont Hospital has said that about half of the people they see in their post-Covid-19 clinic are doing well and feeling better.
But Dr Killian Hurley said the other half have persistent symptoms, including breathlessness, cough and severe fatigue. Patients are usually seen three to four months after they first contract the illness.
Dr Hurley said that with severe Covid patients who were admitted to hospital, the virus can affect organs, including the lungs and heart, as well as muscles and the brain.
People with severe Covid-19 who were admitted to intensive care also have psychological impacts and problems with their memory and cognition.
