AHRQ is leading multiple efforts to better understand Long COVID and support people with Long COVID and the healthcare providers who deliver their care.

What Is Long COVID?

Long COVID is broadly defined as signs, symptoms, and conditions that continue or develop after initial COVID-19 or SARS-CoV-2 infection. The signs, symptoms, and conditions are present for four weeks or more after the initial phase of infection; may be multisystemic; and may present with a relapsing–remitting pattern and progression or worsening over time, with the possibility of severe and life-threatening events or disability even months or years after infection.

Long COVID is not one condition. It represents many potentially overlapping entities, likely with different biological causes and different sets of risk factors and outcomes.

While estimates vary, up to one-third of people with COVID-19 experience Long COVID, with estimates being much higher in females; transgender and bisexual people; people without a bachelor’s degree, particularly those without a high school diploma; and people with a disability. Further, many at-risk and minority populations face barriers that can exacerbate the impact of Long COVID on their lives and complicate their prognosis and recovery.

Examples of such barriers include difficulty with healthcare access, communication, and internet accessibility; lack of health insurance; lower health literacy; greater difficulty using patient portals and telemedicine; higher no-show rates for appointments; and greater medical and social vulnerabilities.

Current Projects on Long COVID

The AHRQ Long COVID Care Network

On September 20, 2023, AHRQ announced nine grant awards to existing multidisciplinary Long COVID clinics across the country to expand access to comprehensive, coordinated, and person-centered care for people with Long COVID, particularly underserved, rural, vulnerable, and minority populations that are disproportionately impacted by the effects of Long COVID. Learn more about the AHRQ Long COVID Care Network.

Medical Expenditure Panel Survey Questions

The Medical Expenditure Panel Survey (MEPS) added questions about Long COVID beginning with spring 2023 data collection rounds. These questions include whether sample members who had COVID-19 had any symptoms lasting 3 months or longer that they did not have prior to having COVID-19, whether the sample member had symptoms at the time of the interview, and if so, how much these long-term symptoms reduced their ability to carry out day-to-day activities compared to before they had COVID-19. These questions are available beginning with the 2022 MEPS data files.  More information on MEPS is available at https://meps.ahrq.gov/mepsweb/. 

Models of Care for Treatment of Long COVID

AHRQ's Evidence-Based Practice Center (EPC) program has developed a new technical brief (evidence map) focused on models of care for people with Long COVID. The report summarizes definitions of long COVID and describes what is known about long COVID models of care, including models currently in use, their applicability to the U.S. population, promising new approaches, advantages and disadvantages of different models, barriers and facilitators to implementation, access and equity issues, and needed research.

Understanding COVID-19 Trajectory and Outcomes in the Context of Multiple Chronic Conditions Through e-Care Plan Development

This project is a partnership between AHRQ and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), funded by the Assistant Secretary for Planning and Evaluation Patient-Centered Outcomes Research Trust Fund (ASPE OS-PCORTF). The project aims to develop a standards-based, interoperable, electronic care (eCare) plan designed to facilitate aggregation and sharing of critical person-centered data across home-, community, and clinical settings to support research and to improve the care of people living with multiple chronic conditions who are at increased risk for adverse outcomes from COVID and developing Long COVID. The project has identified standardized data elements for Long COVID and incorporated them into the e-care plan. Additional details can be found at Understanding COVID-19 Trajectory and Outcomes in the Context of Multiple Chronic Conditions (MCC) through e-Care Plan Development and Multiple Chronic Conditions e-Care Plan Project.

Past Projects on Long COVID

Summit on Best Practices for Treating Long COVID

The Best Practices for Treating Long COVID Summit was held on Jan. 27, 2023, in Richmond, Virginia. Sponsored by AHRQ in partnership with the Office of Senator Tim Kaine, D-Va., the Summit’s goal was to hear directly from patients and clinicians about their experiences with Long COVID.

The discussions were designed to drive Senator Kaine's work (PDF, 150 KB) in the Senate and to further AHRQ’s efforts to support healthcare clinicians and health systems to better provide patient-centered, coordinated care for patients with Long COVID.

Beyond that, the conversation was intended to inform the whole of the U.S. Department of Health and Human Services' (HHS') efforts to address Long COVID, involving patients, caregivers, clinicians, and community organizations in shaping initiatives to address this complex condition.

AHRQ National Advisory Council Discussion on Long COVID

AHRQ's National Advisory Council, which advises AHRQ’s director on Agency activities and priorities, devoted a portion of its March 6, 2023, meeting to Long COVID and Addressing Health System Fragmentation. Subsequent to the meeting, National Advisory Council Chair Edmondo Robinson,  M.D., M.B.A., M.S., authored an AHRQ Views blog post that discussed the unique challenges presented by Long COVID while emphasizing AHRQ's potential to respond to severe gaps that have emerged in our fractured healthcare system.
