The vast majority (86%) were still very tired 165 days after their first symptoms, while 59% still experienced shortness of breath, 36% often felt pressure on their chests, 35% had headaches, and 40% experienced muscle pain.
The overwhelming majority, 94%, were not hospitalised for Covid-19 and only had light symptoms. These were relatively young people, with an average age of 48 years.
About 86% of respondents said they had been in good health before their infection and 61% said they had not had any chronic illness before.
“This is a special population,” the head of the research team, Professor Martijn Spruit (UHasselt/Ciro/Maastricht) explained. “We are now able to carefully compare the evolution of the symptoms linked to the coronavirus in these persons. It’s a study that’s unique in the world.”
