Twelve weeks after his first Covid-19 symptoms, 28-year-old Callum O'Dwyer is still not better.
A fit and healthy young man, he had no underlying health conditions before he caught the virus.
But after five weeks of fighting of the main symptoms, he could no longer look after himself and had to move in with his parents.
Recovery has taken much longer than he imagined and his ongoing symptoms mean he still can't live on his own or work.
Doctors have told Callum he has post-viral fatigue, a hangover from coronavirus which is affecting many survivors.
