[Comment] Long COVID: which symptoms can be attributed to SARS-CoV-2 infection?

Mortality rates following SARS-CoV-2 infection have decreased as a consequence of public health policies, vaccination, and acute antiviral and anti-inflammatory therapies.1 However, in the wake of the pandemic, post-acute sequelae of COVID-19, or long COVID, has emerged: a chronic illness in people who have ongoing multidimensional symptomatology and disability weeks to years after the initial infection.2 Early reports of long COVID prevalence, summarised in a systematic review examining the frequency and variety of persistent symptoms after COVID-19, found that the median proportion of people who had at least one persistent symptom 60 days or more after diagnosis or at least 30 days after recovery from COVID-19 infection was 73%.
