Long COVID Remains a Hidden Crisis Despite Millions Affected
Long COVID continues to affect millions of Americans, with an estimated 17 million adults reporting symptoms in 2024. Despite substantial disability and economic costs, the condition is underdiagnosed and has lost policy attention, including the closure of federal advisory committees. The authors argue that the disconnect between research and clinical practice is leading to inadequate responses.
In early 2024, roughly 7% of U.S. adults—about 17 million people—reported ongoing long COVID symptoms. The associated disability rivals that of major chronic illnesses like Alzheimer's, and projected societal costs were estimated to exceed $3 trillion over a five-year period.
Despite an estimated one-in-six infection rate leading to post-acute sequelae, only about 30,000 new cases are diagnosed annually, indicating significant under-identification. The lack of a definitive lab test complicates diagnosis, leading to confusion with aging, burnout, or psychiatric conditions. Furthermore, federal oversight was dismantled in early 2025, and limited treatment options push some patients toward self-management.
The hidden nature of long COVID could perpetuate a cycle of inadequate clinical support and economic strain for millions. Patients may face delayed diagnoses or dismissive care, potentially worsening their disability and reducing workforce participation. The dismantling of federal advisory structures may further hinder research and standardized treatment protocols. Consequently, the societal burden could remain concentrated among working-age adults and caregivers, while healthcare systems may struggle to allocate resources effectively without clear epidemiological visibility.
