C19LAP urges the rapid adoption and implementation of the 2024 NASEM Long COVID Definition, and encourages all stakeholders, especially patients, caregivers, clinicians, researchers, support services, health agencies, and government, to read the full report. Inconsistent terminology and meaning has limited progress and the generalizability of research findings, inhibiting patients from obtaining the recognition, care, and support they need. This definition should be applied to clinical care and diagnosis, eligibility for health services, insurance coverage, disability benefits, and school or work accommodations, public health, social services, policy making, epidemiology and surveillance, private and public research, and public awareness and education. It should also be utilized by safety net programs, including but not limited to, payers, workplaces and employers, academic institutions and educators.
