Understanding Immunity to the Flu Vaccine in COVID-19 Patients

The purpose of this study is to measure immunity to the flu vaccine over time in patients who have had COVID-19 and may have other medical conditions including obesity, type 2 diabetes, chronic fatigue, or long-term COVID-19 symptoms. Adults and children (age 9 to 64) who had been diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.

Long Term Outcomes of Patients With COVID-19

The investigators hypothesize that those with respiratory failure due to COVID-19 will have different burdens of mental and physical disability than those with respiratory failure who do not have COVID-19. Detecting these potential differences will lay an important foundation for treating long term sequelae of respiratory failure in these two cohorts.

SARS-CoV-2/COVID-19 Study of Next Generation Non-Invasive Passive Detection Technologies

The goal of this observational study is to evaluate new non-invasive passive surveillance technologies, Level 42 AI imPulse™ Una and TOR devices for the detection of COVID-19, Flu, and/or RSV in asymptomatic and symptomatic individuals over age of 18 undergoing COVID-19, Flu, and/or RSV screening and testing at BAMC Ft Sam Houston, TX; with and without COVID-19, Flu, and/or RSV. The hypotheses are: (H1) The imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic COVID-19 carrier versus those not infected compared to gold standard RT-PCR. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their usability between the devices. (H2) Identify if the imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic Respiratory Syncytial Virus (RSV), Influenza and Long COVID carriers versus those not infected compared to gold standard Rapid RSV and Flu Antigen Tests, or RT-PCR and molecular assays. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their captured traces in the early identification of disease/illness analyzed by the devices built in algorithms. (H3) In the mid to long-term, this approach will also be explored as a diagnostic system to explore pursue the physical (structural and mechanical) properties of cells and tissues that maintain normal cell behavior (motility, growth, apoptosis), and the critical importance of the ability of cells to sense and respond to mechanical stresses, which will be operationally critical for assessment of both traumatic and unconventional exposures in austere environments. Participants will: * Be consented; * Be screened for COVID-19, Flu, and/or RSV symptoms according to BAMC's current screening procedures; * Have study data collected; * Complete a symptoms questionnaire; * imPulseTM Una and TOR e-stethoscopes examination will be conducted; * Participants will be compensated for completing all study requirements. (Active-Duty personnel must complete the study procedures while off-duty in order to receive compensation.)

Risk Factors, Clinical Characteristics and Outcomes of Acute Infection With Coronavirus 2019 (COVID-19) In Children

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.

Determinants of SARS (Severe Acute Respiratory Syndrome)-COV2 (COVID-19) Persistence After Convalescence

The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.

KIDney Injury in Times of COVID-19 (KIDCOV)

There is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.

Coronavirus Infection (COVID-19) and Radical Surgery in Patients With Early-stage Lung Cancer

The goal of this observational study is to learn about the effects of coronavirus infection in patients with early-stage lung cancer. The main question it aims to answer is whether the interval of surgery and COVID-19 infection will affect the surgery and prognosis of the patients.
