New research has found that one in ten people, considered low-risk patients with mild Covid-19, report a diversity of long-term symptoms after being infected with the virus.
Previous studies have found that people with severe Covid-19 are at high risk of having long-haul Covid-19. This study, published in JAMA, however, assessed people who had a mild infection, but still presented with long term symptoms.
The researchers collected blood samples from 2 149 healthcare workers from Danderyd Hospital in Sweden between 15 April and 8 May 2020. Thereafter, blood was collected every four months.
