Official Title
A Longitudinal Study of COVID-19 Sequelae and Immunity
Brief Summary

Background: COVID-19 is a disease caused by the SARS-CoV-2 virus. It infects the respiratory tract. Some people who get COVID-19 have only mild symptoms. But for others, infection leads to pneumonia, respiratory failure, and, in some cases, death. Researchers want to learn more about any effects that may persist after people recover from COVID-19. Objective: To learn about any long-term medical problems that people who have recovered from COVID-19 might have, and whether they develop an immune response to SARS-CoV-2 that provides protection against reinfection. Eligibility: People age 18 and older who have recovered from documented COVID-19 or were in close contact with someone who had COVID-19 but did not get the infection Design: Participants will be screened over 2 visits. During visit 1, they will answer questions about any symptoms they are having and will be tested for SARS-CoV-2 infection which will involve a nasal swab sample or other FDA approved test. If the test is negative, they will proceed to the second visit, which will include: Physical examination Medical history Mental health interview (which may be recorded if the participant agrees) Chest x-ray (for recovered COVID-19 participants only) Blood and urine tests Pregnancy test (if needed) Lung function test (for recovered COVID-19 participants only) 6-minute walk test (for recovered COVID-19 participants only) Questionnaires about their general and mental health Leukapheresis to collect white blood cells (optional). Participants will be put into 1 of 2 groups: the COVID-19 group or the close contact group. Participants will have study visits every 6 months for 3 years. They will repeat some of the screening tests. Participants in the COVID-19 group may have visits more often if they develop symptoms that suggest re-infection with SARS-CoV-2....

Detailed Description

Study Description:

This is a longitudinal cohort study to evaluate the clinical sequelae of acute COVID-19 and
characterize the immune response to SARS-CoV-2. Household contacts of the COVID-19 cohort
will also be recruited and serve as a control group.

Objectives:

- Characterize the medical sequalae and persistent symptoms following recovery from
COVID-19 in a cohort of disease survivors.

- Estimate the incidence and risk factors for post-COVID-19 medical sequalae.

- Characterize antibody and cell-mediated immune responses to SARS-CoV- 2 in disease
survivors

- Characterize evolution of the antibody and T cell-mediated responses to SARS-CoV-2 in
survivors over time

- Evaluate survivors for evidence of re-infection with future waves of COVID-19 to
determine if initial infection confers long-term protective immunity

- Determine the incidence of clinically silent infection in household contacts

- Characterize the mental health status of survivors and controls including medical trauma
related sequelae

Endpoint:

Establish a clinically well characterized cohort of persons recovered from COVID-19 and close
contacts of persons with COVID-19

Eligibility Criteria

- INCLUSION CRITERIA:

In order to be eligible to participate in this study, all individuals must meet all of the
following criteria:

1. Stated willingness to comply with all study procedures and availability for the
duration of the study

2. Age 18 years or older.

3. Ability of participant to understand and the willingness to sign a written informed
consent document.

4. Hemoglobin of 9.0 gm/dl or higher

5. Willingness to give consent for the storage of blood samples for research.

6. Have a physician or clinic outside NIH to manage underlying medical conditions or
agreeing to establish care with an outside physician or clinic for any medical
conditions requiring treatment that may be diagnosed as a result of protocol
participation.

COVID-19 Survivor Group

1. Documented prior COVID-19 as evidenced by:

1. detection of SARS-CoV-2 RNA or antigen in nasopharyngeal swab, sputum or other
sample source with EUA/approval from the FDA; or

2. a positive antibody test using an assay that has received emergency use
authorization (EUA) from the Food and Drug Administration (FDA) and a history
clinical manifestation compatible with COVID-19.

2. Greater than 6 weeks since onset of COVID-19 symptoms and no fever for at least 1
week. For individuals with asymptomatic infection, screening will not occur until at
least 4 weeks after the last positive SARS-CoV-2 PCR or antigen test.

COVID-19 Close Contact

1. Living in the same household as a COVID-19 survivor during the time of illness or,
being within approximately 6 feet (2 meters) of a COVID-19 case for a prolonged period
of time or having direct contact with infectious secretions of a COVID-19 case (e.g.,
being coughed on).

2. No diagnosis of COVID-19 or current symptoms suggestive of COVID-19

EXCLUSION CRITERIA:

An individual who meets any of the following criteria will be excluded from participation
in this study:

1. Current abuse of alcohol or other drugs that, in the judgement of the Principal
Investigator (PI) could interfere with patient compliance.

2. Inability to travel to the NIH Clinical Center for study visits

3. Any medical or mental health condition that, in the judgement of the PI, would make
the volunteer unable to participate in the study.

4. Positive SARS-CoV-2 PCR at screening visit

5. Positive test for antibodies to SARS-CoV-2 nucleocapsid protein at the screening visit
(control group only).

6. History of any of the following in the past 14 days: fever > 38.2 degrees Celsius; new
or worsening respiratory symptoms (e.g. cough, dyspnea).

7. Pregnancy
