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.

Background: Respiratory viruses circulate throughout the year and around the globe. Wearable and sensor devices, like smartwatches, may be able to help monitor infectious diseases. Researchers want to use them to learn how respiratory viruses affect people in different ways. Objective: To use digital devices to collect data from participants in challenge studies that could indicate subtle changes in health during an infection that might otherwise go unnoticed. Eligibility: Healthy adults who have enrolled in a challenge study. Design: Participants will stay at NIH for at least 9 days and then they will have outpatient visits. While at NIH, participants will wear a smartwatch at all times. It will record data like temperature, heart rate, breathing rate, and movements. Participants will have 2 smartphones. One will be recording at all times to listen for coughing. Participants will use the other smartphone to check their vital signs. They will collect data like heart rate, temperature, and the level of oxygen in the blood every 4 hours during the daytime. Participants will perform tasks every 4 hours during the daytime. They will record themselves coughing, breathing in deeply, and reading aloud. They will take pictures and videos of their face. A bedside sensor will record participants while they sleep. It will record heart rate and breathing rate. It will also look at sleep activity, such as movements participants make during sleep and how deeply they sleep. Participants sharing the same room will be exposed to the same challenge virus. For outpatient visits, participants will use one smartphone and the smartwatch to complete the above tasks. Participation will last from 10 weeks to 1 year.

Background: The SARS-CoV-2 virus has caused a pandemic. Little is known about the virus, so data is needed to form an effective public health response. Researchers want to count how many people have been exposed to COVID-19, learn about symptoms, and find out how many antibodies to the SARS-CoV-2 virus a person may have in their blood over 1 year. This data could affect the response to current and future pandemics. Objective: To learn how many people from a sampling of adults in North Carolina develop antibodies to the SARS-CoV-2 virus over 1 year. Eligibility: Healthy people age 18 and older who do not currently have COVID-19 Design: Participants will be screened with questions about their health. Participants will have five 30-minute visits at the Clinical Research Unit. At each visit, they will have blood drawn to see if they have SARS-CoV-2 antibodies. If the test result is positive for antibodies, the participant will be tested to see if they currently have COVID-19. For this, a nasal or throat swab will be done, or saliva will be collected. They may do this test at the same visit as the blood draw, or they may schedule an extra visit. Around the time of their study visits, participants will take an online survey about themselves, their health, and COVID-19. It takes 10 minutes to complete. Every week for 52 weeks, they will also take a brief online survey about their symptoms. It takes 2 minutes to complete. They will be emailed a link to log in and fill out the surveys on a secure website. Participation will last for 1 year. ...

Background: COVID-19 is an acute respiratory syndrome. One symptom of COVID-19 is a reduction in the number of cells called lymphocytes in the blood. Lymphocytes are a type of white blood cell that fights infections. With fewer lymphocytes, the body cannot effectively fight back against SARS CoV-2, the virus that causes COVID-19. Researchers want to better understand how SARS-CoV-2 affects these blood cells. This information may give them ideas for new treatments. Objective: To learn more about how SARS-CoV-2 affects lymphocytes, the immune, and the blood clotting system. Eligibility: Adults age 18 and older who either currently have COVID-19 or have recently recovered from it Design: Participants will give a blood sample. For this, a needle is used to collect blood from an arm vein. For participants who have a central line, blood will be collected through that instead. Participants medical records related to COVID-19 will be reviewed. Participants who have recovered from COVID-19 will be asked to undergo leukapheresis to collect white blood cells. For this, blood is taken from a needle placed in one arm. A machine separates out the white blood cells. The rest of the blood is returned to the participant through a needle placed in the other arm. This takes about 2-3 hours. Recovered participants may have material collected from inside the nostrils and/or rectum. This is done by gently rubbing the area with a sterile cotton swab. Recovered participants may have an echocardiogram to look at their heart. For this, a small probe is held against the chest to get pictures of the heart from different angles. This takes less than 30 minutes. Participation lasts 1-2 days on most cases and may be split in a few visits for recovered patients if leukapheresis and echocardiogram are done. ...

We are conducting a research study at the VA hospital in Bedford, MA to learn more about how a multisensor rapid health assessment device, MouthLab, can help predict or anticipate future health complications in patients with underline conditions after contracting COVID-19. The device was created by a health technology and digital medicine company called Aidar Health, Inc. MouthLab is a non-invasive, hand-held device that works like a breathalyzer. An individual breathes into the device for 60 seconds and the MouthLab gathers more than 10 vital health parameters like temperature, heart rate, SpO2, ECG, and basic lung functions. Participation in the study will last for 6 months, and the purpose is to gather health information from people who have been previously hospitalized with COVID-19. We will use the data to develop an algorithm that predicts future complications of COVID-19, especially among patients with complex conditions (i.e., heart failure, chronic kidney disease, diabetes, hypertension, asthma, chronic obstructive pulmonary disease), and enables early intervention.
