The purpose of this clinical trial is to learn about the safety and effects of the study vaccine (called COMIRNATY) for the potential prevention of COVID-19. This study is seeking participants who: 1. Are age <21 years. 2. Have presentation to participating medical center with evaluation in Emergency Room and/or hospitalization. 3. Received either the 1st, 2nd, 3rd or booster dose(s) of COMIRNATY within 7 days of symptom onset. 4. Meet criteria of Centers for Disease Control and Prevention case definition of probable or confirmed myocarditis/pericarditis 5. Are capable of giving signed informed consent/assent (by parents/legal guardians of minors and/or patients), which includes compliance with the requirements and restrictions listed in the Informed Consent/Assent Document and in this protocol OR meets criteria for waiver of consent. This study will examine the potential long-term effects associated with myocarditis/pericarditis following vaccination with COMIRNATY. The association of myocarditis/pericarditis in participants who received the study vaccine (COMIRNATY) compared with those associated with COVID-19 will also be examined. This will help us determine if COMIRNATY is safe and effective, and if there is a myocarditis/pericarditis association that should be noted. Participants will take part in this study for up to 5 years. During this time, they will receive complete cardiac imaging tests, and have follow up visits per guidance stated in the study protocol.

Background: The COVID-19 pandemic has challenged the health systems worldwide. Many tools have been developed in response to the pandemic, but there is no current way to quickly screen multiple people for the disease. Research has shown that people with COVID-19 have higher levels of some proteins involved in the immune response and inflammation. These proteins can be detected in sweat using a special camera. Researchers want to see if analysis of sweat from fingerprints could be used to detect COVID-19 infection in people. Objective: To test a new technology to detect COVID-19 infection based on an analysis of sweat from fingerprints. Eligibility: Adults ages 18 and older who tested positive or negative for COVID-19 within the last 7 days. Design: Participants will visit the NIH Clinical Center for one day within 7 days from COVID-19 testing. The visit will last for 3 to 4 hours. Participants who show symptoms for COVID-19 with a positive test will give blood samples to correlate with the sweat markers. About 1/2 tablespoon of blood will be drawn. For sweat markers, 10 fingers will be imaged by a camera using a touchless system. This will be repeated 3 times. It will take about 15 minutes. Participants will use the device. They will get instructions and watch a short video on how to use the device.

Background: - Viral infections are an important cause of illness and death in hospitalized patients as well as outpatients. New strains of viruses may appear and infect both healthy people and those with weak immune systems. A better understanding of these new virus strains (such as SARS-CoV-2, the virus that causes COVID-19) may help to control and prevent these infections. In particular, some viral infections that are less problematic in healthy persons can be life threatening in persons with weak immune systems, and viruses may be able to evolve more rapidly in persons with weak immune systems and therefore develop resistance to existing treatments. Researchers are interested in collecting samples and information from otherwise healthy persons or persons with weak immune systems to study the effects of viruses and their development. Objectives: - To collect samples and data from individuals who have been exposed to or have contracted viral infections. Eligibility: - Individuals of all ages who have been diagnosed with a viral infection are suspected to have a viral infection, or have been in close contact with someone with a suspected or actual viral infection that is of interest to investigators in the Laboratory of Infectious Diseases. - Healthy persons and persons with weak immune systems (immunocompromised individuals) are eligible to participate. Design: - Participants will be pre-screened to determine if they meet the eligibility criteria for the trial. - If eligible, evaluation may include a medical chart review, a history and physical examination, review of clinical reports from outside hospitals and laboratories, and review of tissue biopsies. - Study procedures may include collection of blood, urine, saliva, nasal fluid sampling, throat swabs, stool, and genital swabs. For participants who have specimens collected as part of their medical care (e.g. wound swabs, spinal tap, bronchoscopy, liver biopsy etc.), researchers may use leftover specimens from the clinical laboratory for testing. - Specimens may be collected up to 4 times per week during the first 2 weeks after enrollment, and then as many as 2 times per week for up to 2 years. Some participants may be asked to continue providing specimens if there is concern for relapse or recurrence of the infection. - Treatment is not offered under this study.

Background: COVID-19 can cause problems in different parts of the body. For most people, it causes fevers or trouble breathing. Some people might not recover all the way. Researchers want to see if a treatment can help with people who have recovered from COVID-19 but still have symptoms ("Long COVID"). Objective: To learn if human immunoglobulin (IVIG) will help with neurological symptoms of Long COVID. Eligibility: Adults ages 18 and older who had COVID-19 at least 12 weeks ago and have ongoing neurologic symptoms, such as dizziness, trouble walking, or problems with strength. Design: Participants will be screened with a medical record review. Participants will have a medical history and a physical exam and complete questionnaires about their health and quality of life. They will have a spinal tap. They will give blood samples. They will discuss their symptoms with a neurologist and have a neurological exam. Participants will take memory and thinking tests using a tablet. The tests will take 1 hour to complete. They will also take a smell and taste test. It will take approximately 30 minutes to complete. Participants will lie on a table that tilts for up to 40 minutes. Their blood pressure and heart rate will be monitored. Blood will be taken through an intravenous (IV) catheter. Participants will receive either IVIG, or saline by IV for 5 days. Then the participants will receive IVIG if they first received saline or saline if they first received IVIG by IV for another 5 days. They will not know what they receive. Participants will have an MRI of the brain if they have not had one recently. They will receive a contrast agent by IV as part of the MRI scan. Participants will be on the study for up to 4 months. They will have follow-up visits at the clinical center as well as fill out questionnaires at home. They may be asked to continue follow-up....

This is a cohort study that will include Paxlovid (nirmatrelvir-ritonavir) treatment eligible for people with a positive SARS-CoV-2 diagnostic test and at least one COVID-19 symptom. This study will look at the change in Post Covid Conditions measured by the number of outpatients, Emergency department, urgent care and inpatient visits before and after COVID-19 between those who did and did not receive Paxlovid. In addition, changes in frailty post-acute infection will be evaluated, in a separate analysis. It is hypothesized that individuals with COVID-19 who received Paxlovid will have a smaller post-COVID-19 increase (vs pre-COVID) in PCC healthcare utilization (i.e., cardiopulmonary) in comparison to patients with COVID-19 who did not receive Paxlovid.

The goal of this clinical trial is to test whether a type of rapid outpatient brain stimulation that uses magnetic fields, called accelerated intermittent theta burst stimulation (iTBS), can treat symptoms such as brain fog, depression, and anxiety in patients with Long COVID. The main questions it aims to answer are: - Is iTBS effective and feasible for reducing Long COVID symptoms? We will measure these symptoms using the Symptom Burden Questionnaire. - Are there changes in inflammatory brain chemicals associated with treatment with iTBS? We will be looking at levels of choline in the brain, which is thought to be related to inflammation. Researchers will compare sham versus active forms of iTBS to see if the active group has greater improvement in symptoms. Participants will complete symptom surveys, cognitive tests, and magnetic resonance imaging scans at the beginning, middle, and end of treatment.

Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other medicines that may react with a treatment and cause an unwanted effect. Molnupiravir (MK-4482) is a study medicine designed to stop the COVID-19 virus from copying itself in the body (multiplying). The goal of this study is to learn if molnupiravir prevents severe illness from COVID-19 more than placebo in people who are high risk.

Face masks have become a critically important public health intervention after the COVID-19 pandemic. Multiple types of masks ranging from full face filtering to cloth masks have been developed and commercialized to facilitate protection against respiratory pathogens. Most of these systems are made with opaque fabrics and may prevent individuals from expressing emotions or for those who are deaf and hard of hearing, communicating. To date, few transparent face masks which also confer respiratory pathogen protection have been developed. This study will test the feasability and acceptability of two new masks, the SEEUS-95 mask and CrystalGuard mask which are both transparent versions of N-95 filtering face masks.

Diaphragm is the principal muscle of inspiration. Diaphragmatic dysfunction is seen in many conditions including following intubation, lung disease, prolonged ventilation, neuromuscular disease, phrenic nerve injury. The possible mechanisms of diaphragmatic dysfunction in patients with COVID19 are critical illness myopathy, ventilator-induced diaphragm dysfunction, iatrogenic phrenic nerve injury particularly secondary to line placement, post-infectious inflammatory neuropathy of the phrenic nerve, or possibly direct neuromuscular involvement of the SARS- CoV-2 virus given expression of the angiotensin- converting enzyme 2 (ACE2) receptor in the peripheral nervous system and skeletal muscle. The use of diaphragmatic ultrasound has been widely used to assess diaphragmatic function is well known in patients following prolonged mechanical ventilation. Prolonged mechanical ventilation leads to contractile dysfunction of respiratory muscles, in particular the diaphragm, causing a so-called ventilator-induced diaphragm dysfunction. The latter is defined as a loss of diaphragm force-generating capacity specifically related to the use of mechanical ventilation. However, the use of diaphragmatic Ultrasound to assess its function in Long COVID patients has not been noted and is a gap in the work up of these patients. The purpose of this study is to address Diaphragmatic Dysfunctional (DD) breathing seen in patients with Post-Acute Sequelae of COVID-19 (PASC), which results in shortness of breath/chest tightness and subsequent fatigue. Targeting shortness of breath and subsequent fatigue as a central symptom of PASC will alleviate long term sequelae for the patients with PASC. DD will be addressed by a unique intervention of physical therapy. The goal of this prospective randomized clinical study will be to evaluate the comparative treatment effect of DB on markers, specifically fatigue, dyspnea, 6 min walk test, depression/anxiety, and quality of life (QoL).

This study tests the effectiveness of a community-based peer advocacy, mutual learning, and social support intervention (Refugee and Immigrant Well-being Project) to reduce several negative consequences of the COVID-19 pandemic that are disproportionately impacting Latinx and Black populations: psychological distress, financial problems, and daily stressors. In partnership with five community-based organizations that focus on mental health, legal, education, and youth issues with Latinx immigrants and African refugees, we will also be able to examine the effects of people's involvement with community-based organizations and local and state policy changes on their mental health, economic stability, stressors, and social support. This is important not only for Latinx and Black populations and the large number of immigrants and refugees in the United States and worldwide, but also because the intervention model and what we learn from this study have the potential to alleviate mental health disparities experienced by other marginalized populations who face unequal access to social and material resources, disproportionate exposure to trauma and stress, and worse consequences of the COVID-19 pandemic.
