RECOVER: Researching COVID to Enhance Recovery

The National Institutes of Health (NIH) created the RECOVER Initiative to learn about the long-term effects of COVID.

Everyone can join the search for answers to Long COVID.
Whether or not you have had COVID, you may be able to participate in RECOVER research.

RECOVER research aims to understand how people recover from a COVID infection, and why some people do not fully recover and develop Long COVID or PASC (post-acute sequelae of SARS-CoV-2).

Volunteers are still needed to help us understand COVID and its effects.

Whether you have COVID now, had COVID before, or never had COVID, you may be able to participate.

We need to learn how COVID affects all people from all walks of life and across the country and that means adults, including pregnant people, and children.

Study locations will enroll people with different experiences with COVID. They will also make sure that all people are represented until goals are met.

People are joining the search for answers.

Thousands of children and adults - including pregnant people - have joined RECOVER studies. People with and without COVID can help us learn why and how Long COVID affects some people and not others. With your help, we can learn about the long-term impact of COVID on many different people.

We’re learning by including diverse perspectives.

Including people of all races and ethnicities, genders, ages, and locations in our research helps us understand how Long COVID affects everyone.

Millions of people have had COVID-19 — and in many ways, people of color have been hit hardest.

Studies show that people of color are more likely than white people to go to the hospital for health issues related to COVID-19.

American Indian or Alaska Native
3.1xMore likely
Black or African American
2.4xMore likely
Hispanic or Latino
2.3xMore likely
0.8xMore likely

We learn more when we work together.

Teamwork is at the heart of RECOVER. Researchers, health care professionals, and organizations across the country are working together to find answers. Our studies include many different groups of people — like adults, pregnant people, and children and their caregivers.

More than
500 million
people around the world have had COVID. It’s possible that millions of them could have long-term health effects.

Duke Selected as RECOVER Clinical Trials Data Coordinating Center

The Duke Clinical Research Institute (DCRI) has been named the Clinical Trials Data Coordinating Center (DCC) for the RECOVER Initiative. DCRI will partner with the RECOVER Administrative Coordinating Center (ACC), based at RTI International, to oversee the study’s clinical trials infrastructure, establish a patient registry, launch prevention and therapeutic multi-intervention studies for adults and children, and work to accelerate the clinical trial process. The DCC will align with existing COVID research projects, including the RECOVER Consortium and the NIH-funded ACTIV (Accelerating COVID-19 Therapeutic Interventions and Vaccines) studies.

NIH Director’s Blog: Using AI to Advance Understanding of Long COVID Syndrome

One of the most puzzling aspects of the COVID-19 pandemic is understanding why some people who have short-term COVID later develop new symptoms. Or they may continue to have symptoms while also developing new ones. These Long COVID symptoms can vary a lot from person to person, which makes it hard to understand why some people are more likely to have Long COVID. In this blog post, NIH Director Lawrence Tabak, DDS, PhD, discusses an important new RECOVER study published in The Lancet Digital Health that used artificial intelligence computer models to help unravel this mystery.

RECOVER Publication: Scientists use Electronic Health Records and Machine Learning to Better Define Long COVID

In a study published in The Lancet Digital Health, Pfaff and colleagues used electronic health record (EHR) data to find more than 100,000 likely cases of Long COVID in an EHR database of more than 13 million people.

The study findings will help researchers understand the characteristics and risk factors linked to Long COVID diagnosis and will also help identify potential Long COVID patients for clinical trials.

RECOVER Adult Study Protocol Available

The full RECOVER research protocol, or study plan, for adults taking part in RECOVER studies is now available. We are finished planning the adult study protocol, but the protocol may change over time as we learn more. If the protocol is updated, we will share it on the RECOVER website, A version of the protocol in easier to understand language will be available soon.
