A research agenda for post-COVID-19 fatigue (Editorial)

Abstract

Now that the COVID-19 pandemic has been ongoing for almost two years, increasing attention is directed towards what is being called ‘Long COVID’ or ‘post-acute sequelae SARS-CoV-2 infection’ (PASC). Fatigue is one of the main symptoms of PASC. Prevalence rates of fatigue persisting for months after COVID-19 onset range from 9% to 58% depending on time of follow-up, study population, recruitment method and in-depth evaluation.
