It has been two years since the publication of one of the first meta-analyses investigating the prevalence of post-COVID symptomatology but differentiating between hospitalized and non-hospitalized patients [1]. This meta-analysis summarized evidence up to December 2020 on the prevalence of post-COVID symptoms and found that more than 60% of patients who had survived a SARS-CoV-2 infection experienced post-COVID symptoms three months after the infection, and that post-COVID symptoms seemed to be similar between hospitalized and non-hospitalized patients.
