COVIMPACT: Long-COVID and the health consequences after three months of follow-up [Smith et al. 2021]

Smith and colleagues assessed the health of Belgian Long-COVID patients using two surveys: one just after the confirmation of a positive COVID-19 test and one three months later. This report shows that 47% of the 1658 respondents reported at least one COVID-19 related symptom three months after the diagnosis. In this group, one out of two persons reported at least three different symptoms. The most prevalent symptoms were fatigue, headache, and memory or concentration problems. In addition to the physical consequences, the report also sheds light on the mental and social health impact after a COVID- 19 infection.
