More than three quarters of coronavirus patients have at least one ongoing symptom six months after initially becoming unwell, according to a new study.
The research looked at the long-term effects of Covid-19 on people admitted to hospital in Wuhan, China, and found that the most common symptom to persist is fatigue or muscle weakness, in 63% of patients.
Patients also frequently experience sleep difficulties (26%), and anxiety or depression was reported among 23% of patients, according to the study.
Researchers found patients who were severely ill in hospital more often had impaired lung function and abnormalities detected in chest imaging - which could indicate organ damage - six months after symptom onset.
