Months after first being infected with coronavirus, tens of thousands of patients are still experiencing a string of health problems.
These can include fatigue, breathlessness, muscle aches, memory loss, hair loss and depression - with survivors listing around 170 symptoms.
Known as Long Covid, experts believe it could come one of the worst legacies of the pandemic, with Health Secretary Matt Hancock yet to deliver promised support for those still experiencing difficulties.
Experts believe there could be up to 600,000 people in the UK alone suffering the long-term effects of Covid-19. A study by health app ZOE, endorsed by NHS Wales and NHS Scotland, found one in 10 patients experience effects for more than three weeks.
