According to a publication from the European Centre for Disease Prevention and Control (ECDC) released on 31 October, the risk of post-Covid-19 disease may be higher in people who have experienced a severe form of the disease.
A systematic review and meta-analysis based on studies conducted in the European Union (EU) and European Economic Area (EEA), the United Kingdom, the United States, Canada, Australia and New Zealand, indicates that five selected post-Covid-19 symptoms appear to be more prevalent among patients in hospital settings than in community settings.
However, ECDC points out that the report contains some limitations. Thus, the majority of the studies included lacked uninfected comparison groups, which may lead to a bias: an overestimation of symptoms specifically attributable to previous SARS-CoV-2 infection. In addition, the ECDC points to a time lag between the design of the study, its implementation and publication, and the persistence of many unknowns.
The ECDC therefore recommends, among other things, that additional large-scale population-based studies with appropriate control groups be conducted in the future.
