Abstract
Over the past year, the SARS-CoV-2 pandemic has swept the globe, resulting in an enormous worldwide burden of infection and mortality. However, the additional toll resulting from long-term consequences of the pandemic has yet to be tallied. Heterogeneous disease manifestations and syndromes are now recognized among some persons after their initial recovery from SARS-CoV-2 infection, representing in the broadest sense a failure to return to a baseline state of health after acute SARS-CoV-2 infection. On 3 to 4 December 2020, the National Institute of Allergy and Infectious Diseases, in collaboration with other Institutes and Centers of the National Institutes of Health, convened a virtual workshop to summarize existing knowledge on postacute COVID-19 and to identify key knowledge gaps regarding this condition.
The workshop also highlighted the need to recognize the full clinical spectrum of postacute COVID-19, as well as the need to characterize the phenotypes of disease that are beginning to emerge and identify risk factors for their development. Weakness, cognitive dysfunction, and psychological disorders after hospitalization for severe COVID-19 may overlap with the well-described post–intensive care syndrome seen with other critical illnesses (14). Persistent fatigue, cognitive dysfunction, and other multisystemic symptoms after COVID-19 in persons who did not require hospitalization for their acute infection may characterize another distinct phenotype. Autonomic dysfunction and postural tachycardia may represent yet another. Comparisons have been drawn between postacute sequelae of COVID-19 and myalgic encephalomyelitis/chronic fatigue syndrome because many symptoms overlap. Care must be taken not to conflate the 2 conditions because neither is completely understood. Lessons learned from several decades of studying myalgic encephalomyelitis/chronic fatigue syndrome may be applied to studies of postacute COVID-19—and in fact, better understanding of both conditions may be mutually beneficial to patients in both groups.
Key Gap: A Need to Understand Pathophysiology
The pathophysiology that drives the diversity of postacute COVID-19 manifestations is poorly understood. Elucidating the pathophysiology not only will be critical for developing treatment of postacute COVID-19 but may also improve our understanding of the sequelae of other viral infections (for example, influenza, chikungunya, Ebola, and Epstein–Barr viruses) or conditions where viral infection may be suspected but not confirmed (such as some cases of myalgic encephalomyelitis/chronic fatigue syndrome). Workshop speakers and participants discussed potential disease mechanisms underlying postacute COVID-19.
