The Challenge of Long COVID: Is the Pandemic Really Over?

Sequelae of SARS-CoV-2 infection began appearing among patients who had COVID-19 within months of the first wave of the COVID-19 pandemic in 2020. This phenomenon, termed and also known as , has been a source of controversy among physicians, as presentation of long COVID has been a somewhat mysterious constellation of signs and symptoms that seem mostly impervious to efficacious treatment. Although a considerable amount has been learned about the pathophysiology and other biomedical features of long COVID, the epidemiologic parameters of long COVID, including incidence and prevalence, are uncertain in the United States and globally. The best estimates are that millions of people have long COVID. Despite the declining incidence of COVID-19, the low case fatality of long COVID suggests that its prevalence is poised to continue to grow. This increasing prevalence of long COVID presents a challenge for the public health sector. Here, we examine the public health implications of long COVID. We offer policy recommendations, including ending congratulatory talk that the pandemic is over, encouraging more focused attention from the United States and global nongovernmental organizations, and establishing a multinational research initiative to better understand and respond to long COVID and other postviral and postinfectious chronic conditions. Although COVID-19 may not be as widespread and disruptive as in the early months of the pandemic, it would be a mistake to presume that, because the acute crisis is behind us, the pandemic is past. Long COVID is an ongoing public health threat and merits our concern.
