The corona virus disease (COVID) pandemic has highlighted the importance of rapid, readily available screeners and diagnostics to identify infected individuals. Recent studies have demonstrated that portable electronic nose sensing devices can detect volatile organic compounds (VOCs). These compounds are end products of human metabolism or of enteric bacteria and are excreted through the skin or exhaled breath. Importantly, the sensing devices can be adapted into a wearable device providing continuous monitoring. Our goal is to develop a battery-free, electronic nose sensor to serve as a screener and detect VOC patterns associated to patients with symptomatic and asymptomatic COVID-19 without being invasive. To test the screening ability, devices will be worn by COVID-19 positive and negative patients hospitalized at Nebraska Medicine.

Background: Coronavirus 2019 (COVID-19, or SARS-CoV-2) is a serious public health problem, and genetics may play a role in how serious the illness becomes in certain people. Genes are the instructions that our body uses to grow and develop. Variations in our genes can cause medical conditions and may be the reason why some people get sicker than others. Objective: This study aims to learn more about the genetic contributions to the severity of COVID-19. We hope to use this information to develop therapies that reduce the severity of COVID-19 symptoms in some people. Eligibility: Anyone located in the United States who has tested positive for SARS-CoV-2 infection may be eligible to join (including NIH staff). Design: Participants will complete a questionnaire about their health history and COVID-19 symptoms. Participants will give a blood or saliva sample. It will be about 2 tablespoons of blood, or we will send a saliva collection kit. Researchers will use this blood or saliva sample to study the participant s DNA. The data about participants genes will be stored in a large database. The database will be shared with other qualified researchers who are trying to learn about COVID-19. Participants names and other personal details will not be shared. Instead, the data will be labeled with a code. Participants may be contacted by study team members for up to a year after they join the study.

Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have symptoms that last long after the active infection ends. This is called long COVID. Sometimes, long COVID can affect the nerves and cause problems with sleep, thinking, the senses, and movement. Researchers want to find out whether people with long COVID have retained inactive remnants of SARS-CoV-2 in their bodies. Objective: To collect tissue samples to see if people with long COVID have remnants of SARS-CoV-2 in their bodies. Eligibility: People 18 years or older who have recovered from COVID-19, both with and without neurologic symptoms. Design: Participants will have 2 to 4 inpatient or outpatient visits over 4 months. Each visit will last 4 to 5 days. Participants will be screened to make sure it is safe to collect tissue samples from their body. They will have a physical and dental exam. They will have imaging scans and a test of their heart function. They will complete questionnaires about their health. They will give blood, urine, saliva, and stool samples. Their sense of taste and smell will be tested. Tissue samples will be taken from the digestive tract, lungs, colon, skin, muscle, lymph nodes, nasal passages, and mouth. Participants may be numbed or sedated for some of the procedures. Swabs will be used to collect cells from inside the mouth and nose. Participants will undergo lumbar puncture. A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Participants will have follow-up phone calls after each clinic visit.

Racial and ethnic minority children who live in socioeconomically disadvantaged communities are disproportionately impacted by pandemic and climate-induced disasters. Although effective interventions have been designed to treat mental health related symptoms in post-disaster settings, accessible, empirically supported prevention interventions are needed to prevent the onset of mental and behavioral health issues among these children. Building on our preliminary findings, the proposed study examines the efficacy and implementation of a COVID-19 adapted disaster focused prevention intervention, Journey of Hope-C19, in preventing behavioral health and interpersonal problems among racial and ethnic minority children who live in low-resource high poverty communities.

For caregivers in the Bronx, the pandemic has caused unprecedented psychological distress; in addition to combating social determinants of health (SDOH), these families now face greater financial insecurity and challenges related to their school-aged children. Furthermore, social distancing requirements and limited telehealth resources for Bronx families have posed greater barriers to healthcare. Such parental distress contributes to heightened risk of transgenerational cycles of psychological stress, trauma and maltreatment. The social and economic impacts of the COVID-19 pandemic have had significant consequences for family well-being, putting parents at higher risk of experiencing distress and potentially impairing their ability to provide supportive care to their children. Although children may be less susceptible to the most damaging physical consequences of COVID-19, there are growing concerns regarding the short-and long-term impacts of pandemic-related stressors on children. The marked upheaval of family life over an extended period may make children vulnerable to mental health consequences associated with the public health crisis and infection mitigation efforts. School and childcare closures, unstable financial circumstances, social isolation and lack of support have a disproportionate, cumulative impact on parents and may undermine their capacities to provide support for their children. Importantly, a large body of evidence suggests that parental stress during times of disasters induces psychopathologies in family members including children. Further, high anxiety and depressive symptoms in parents during the pandemic have been associated with higher child abuse potential, whereas greater parental support was associated with lower perceived stress and child abuse potential. In addition to psychological impacts, stress associated with caregiving can interfere with parents' ability to maintain their own health. This multimodal study addresses key strategies to mitigate the psychological and health impact of COVID-19 in parents.
