Patient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective - To determine the clinical characteristics and outcomes of Covid-19 in children. - To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives - To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. - To evaluate the duration of SARS-CoV-2 viral shedding in children.

Background: Loss of the sense of smell can seriously affect a person s quality of life. The ability to smell can be damaged by many factors, including illnesses, injuries, and exposure to toxic chemicals. The effects can vary, including complete loss of smell, partial loss, and parosomia, which is when things smell differently than they should. Objective: To study how brain function changes in people with different types of smell disorders. Also, to look at how smell loss affects quality of life over time. Eligibility: People aged 18 years or older with a disorder that affects their sense of smell. Healthy volunteers are also needed. Design: Participants will have 5 study visits over 1 year. They will have various tests and procedures: Smell tests. They will have several tests that involve smelling different items and answering questions. Questionnaires. They will answer questions about their health, mood, sense of smell, and daily habits. Magnetic resonance imaging (MRI) scans. They will lie on a bed that slides into a tube. Padding will hold their head still. They will smell different odors while in the scanner. Electrobulbogram (EBG). They will wear a soft cap with sensors that measure brain activity. They will smell different odors while wearing the cap. Nasal endoscopy. A flexible tube will be inserted into a nostril to view the inside of the nose. Biopsy. A numbing substance will be sprayed into the nose. Then a scissor-like tool will be used to collect a sample of tissue from one or both nasal passages. Samples of blood, urine, and nasal fluid will be taken.

The purpose of this study is to find out whether the COVID pandemic has affected participants' current physical activity, fitness, blood pressure, sleep, and mental stress to better understand its long-term health effects. To complete this study, participants will visit the Neurovascular Physiology Laboratory (NVPL) at the Indiana University School of Public Health Bloomington two times, requiring a total commitment of about 6 hours. Visit 1 involves completing screening questionnaires, a consent document, and additional questionnaires about participant health behaviors (e.g., sleep and physical activity) and general mental and physical health. After the visit, participants will also start tracking their sleep and physical activity using wearable devices for 14 days, diet for at least 3 days, and blood pressure and urine for 24 hours. Visit 2 is a second data collection visit, where participants will return the wearable devices. The investigators will measure participants' body composition, take measures of their cardiovascular health, and participants will complete a fitness test on a stationary cycle (exercise bike). The investigators will collect a 24 hour urine sample and take a blood sample to measure participants' blood glucose, electrolytes, hydration biomarkers, and markers of inflammation, as well as to study immune cells. The investigators will take participants' blood pressure at rest and during a hand-in-cold water test, which helps assess how participants' nervous system responds to stress. A full-body scan will measure participant body composition including bone density, muscle mass, and body fat percentage. Finally, participants will complete a cycling test that gradually increases in intensity to measure cardiovascular fitness. Risks involve potential pain or bruising from blood draws, discomfort from blood pressure cuffs, stress from vigorous cycling, and psychological stress from questionnaires. There's also a slight risk of severe cardiovascular events occurring during exercise and loss of data confidentiality. Finally, the cold water test may result in a rare but noted situation where the body's nervous system overreacts to the cold stimulus, leading to a drop in blood pressure and heart rate. Participants will be monitored by trained staff during all procedures to ensure safety.

This phase I trial tests the feasibility and safety of genetically modified cytotoxic T-lymphocytes in controlling infections caused by adenovirus (ADV), BK virus (BKV), cytomegalovirus (CMV), JC virus (JCV), or COVID-19 in immunocompromised patients with cancer. Viral infections are a leading cause of morbidity and mortality after hematopoietic stem cell transplantation, and therapeutic options for these infections are often complicated by associated toxicities. Genetically modified cytotoxic T-lymphocytes (CTLs) are designed to kill a specific virus that can cause infections. Depending on which virus a patient is infected with (ADV, BKV, CMV, JCV, or COVID-19), the CTLs will be designed to specifically attack that virus. Giving genetically modified CTLs may help to control the infection.

Healthcare workers and COVID-19 patients may experience psychological distress consequent to the pandemic, and are at particularly elevated risk for experiencing posttraumatic stress disorder (PTSD), based on evidence from previous infectious disease outbreaks. The best-validated treatment for PTSD is exposure therapy. Exposure therapy help patients suffering from PTSD to revisit and overcome their traumatic experiences. Including virtual reality in exposure therapy has a long history in treating PTSD; and has been used to treat military veterans and first-responders following 9/11. The investigators are developing and testing a virtual environment to treat PTSD including sub threshold PTSD symptoms in HCWs who experience occupational related trauma (e.g., working with COVID-19 patients) and COVID-19 patients. An independent evaluator will assess symptoms of PTSD and other psychopathology, using structured clinical interviews and self-report measures with well-established psychometric properties, at baseline, halfway through treatment, after completion of treatment, and at three-months post-treatment. Participants will complete ten ninety minute sessions (in-person or remotely), twice a week for five weeks aimed at mitigating their symptoms of PTSD. Remote participants will receive VR headsets after the baseline assessment and will keep them for the duration of the study. The pilot study will aim to demonstrate the feasibility and the tolerability of the virtual reality intervention in these populations.
