Researchers at North Bristol NHS Trust found that 81 out of 110 discharged patients were still experiencing symptoms such as breathlessness, excessive fatigue and muscle aches when invited back to clinic.

Many were also suffering from poor quality of life compared to the rest of the population, struggling to carry out daily tasks such as washing, dressing, or going back to work.

Most of the patients did, however, report improvements in their initial symptoms of fever, cough and loss of sense of smell.
Reassuringly, the majority of patients had no evidence of lung scarring or reductions in lung function.
