CDC Science and the public health approach to Long COVID

Overview

Long COVID is an an infection-associated chronic condition that occurs after SARS-CoV-2 infection and is present at least 3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems. Long COVID affects millions of people across the United States and increases healthcare needs. Health departments play a crucial role in surveillance, communication, and education to increase awareness, reduce stigma, and improve care.

CDC and its partners are conducting research on Long COVID in a variety of populations and settings and are actively working to:

• Disseminate clinical guidance and share epidemiologic and surveillance data to inform public health policy and action.
• Create and increase access to Long COVID educational and communication resources.
• Support clinical capacity by connecting clinicians and public health professionals to Long COVID clinical guidance, resources and educational opportunities.

Key findings

Prevalence

Long COVID estimates vary due to different study criteria, symptoms investigated, patient populations, and timing of when symptoms are assessed. CDC collects and analyzes data through several public health surveys. In 2022, 6.9% of adults and 1.3% of children (roughly 17 million and 1 million, respectively) in the United States ever reported experiencing Long COVID.^(4-5)

While Long COVID can occur in anyone who gets a SARS-CoV-2 infection, some people or groups of people are at higher risk of developing Long COVID. These include women, people with underlying conditions, people who experienced more severe outcomes of COVID-19, and people of Hispanic ethnicity. ^(4,9,10) Approximately 1 in 4 adults with Long COVID reported experiencing significant limitations in their daily activity.^(6-8)

Symptoms

More than 200 Long COVID symptoms have been identified. However, fatigue, brain fog, and exhaustion (post-exertional malaise) are among the commonly reported symptoms of Long COVID. ^(11.12)

Prevention

COVID-19 vaccination is the best available tool to reduce the risk of Long COVID. End of
Translation Research shows that COVID-19 vaccination prior to SARS-CoV-2 infection reduces the risk of developing Long COVID among both children and adults. ^(1-3)

Public health approach to Long COVID

Collaboration between federal agencies and public health partners is important to address the serious nature of Long COVID. CDC has identified key areas of support that clinicians and public health professionals need to empower their efforts to address Long COVID.⁽¹³⁾

Surveillance and epidemiology

Using a variety of data sources to better understand and estimate the:

• Incidence and prevalence of Long COVID
• Economic, social, and clinical burden of Long COVID
• Impact of Long COVID in certain populations who are disproportionately affected
• Role of COVID-19 vaccination and other mitigation measures in preventing Long COVID

Communication and public education

Creating and increasing access to educational and communication resources to inform people about:

• Long COVID as a serious infection–associated chronic condition
• Prevention and management of Long COVID
• Connecting individuals to existing resources and support groups to combat stigma and feelings of isolation, and to provide validation

Clinical capacity

Supporting clinician efforts to effectively diagnose and manage Long COVID by:

• Connecting clinicians to continuing education opportunities and webinars focused on Long COVID
• Sharing information and increasing access to clinical resources and guidance for Long COVID

What CDC is doing

CDC continues to collaborate with clinicians, public health partners, and other federal agencies to better understand and address the impacts of Long COVID. CDC supports these goals by:

• Monitoring the burden and impact of Long COVID on various populations through TrackPCC, a study tracking Post-COVID Conditions
• Sharing data and research aimed at better understanding COVID-19 and Long COVID
• Supporting free clinician education through CDC’s Clinician Outreach and Communication Activity (COCA) calls

Explore CDC data

CDC’s research and data on Long COVID can be accessed through:

• Scientific publications
• Reports
• Data briefs

Prevalence data can be readily accessed from the National Center for Health Statistics rapid survey systems. Inclusion of data and analyses of Long COVID by race/ethnicity, age, sex, and other factors are a CDC priority.
