Clinical Validation of the Aptitude Medical Systems Metrix Respiratory Panel Test in At-Home/Non-Laboratory Settings

The Metrix Respiratory Panel Test will be evaluated for use in Non-Laboratory settings in a home testing environment utilizing the clinical study design described herein. The study will take place in simulated home environments which will be set up within or near active clinical settings (e.g., urgent care facilities). This will be a prospective study conducted at three or more investigational sites located within the United States for the clinical validation of the Metrix Respiratory Panel Test for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory syncytial virus, and Rhinovirus in anterior nares (AN) swab samples. Additional sites may be added to the study in order to meet minimum subject/sample enrollment requirements and geographic prevalence of respiratory virus infections. Comparator testing will be performed to determine the infection status of each sample for comparison to results generated by the candidate test. The primary comparator for the study will be an FDA-cleared assay for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory Syncytial Virus, and Rhinovirus.

Respiratory Syncytial Virus Infection in Exacerbations of Chronic Obstructive Pulmonary Diasease: the RECODE Study

The goal of this observational study is to determine the prevalence of respiratory syncytial virus (RSV) infection and evaluate its association with clinical outcomes in patients with chronic obstructive pulmonary disease (COPD) who experience exacerbations during the RSV season (October-April). The main question it aims to answer is: * What is the prevalence of RSV infection in patients with COPD during exacerbations in the RSV season? * Does RSV infection lead to worse clinical outcomes, including hospitalization, longer length of stay, acute cardiovascular events, and/or death in patients with COPD exacerbations? Researchers will compare patients with RSV infection to those without RSV infection to see if RSV infection results in worse clinical outcomes, such as increased hospitalization, longer stays, cardiovascular events, or death. Participants will: * Be adults diagnosed with COPD who present to the emergency department or day hospital due to acute exacerbations of their respiratory symptoms. * Receive treatment as per standard clinical care for COPD exacerbations, including long-acting bronchodilators and inhaled corticosteroids, and may complete a course of antibiotics and/or oral corticosteroids if prescribed during hospitalization. * Undergo diagnostic testing for RSV infection as part of the clinical routine to determine the presence or absence of the virus during their exacerbation. * Have clinical outcomes monitored, including hospitalization rate, length of stay, and any acute cardiovascular events, as well as mortality during the exacerbation period. * Provide relevant demographic and clinical data, including medical history, COPD severity, comorbidities, and previous exacerbation events.

COMMUNITY - the COVID-19 Immunity Study

The principal aim of the COMMUNITY study is to investigate immune responses following SARS-CoV-2 infection and/or vaccination in healthcare workers and hospitalized COVID-19 patients. The study aims to enroll a total of 5,000 healthcare workers and 500 COVID-19 patients. All participants are enrolled at Danderyd Hospital in Stockholm, Sweden. Participants will be followed every four months with blood and mucosal sampling in addition to demographic and clinical data provided by the participants and from national registries. Primary outcome: \- Antibody responses in blood and mucosa following SARS-CoV-2 infection and/or vaccination Secondary outcomes: * Cellular immune responses following SARS-CoV-2 infection and/or vaccination * Antibody responses in blood and mucosa following following Influenza A/B infection and/or vaccination * Antibody responses in blood and mucosa following following RSV A/B infection Blood and mucosal samples are collected every 4 months and at tighter intervals in sub studies. PCR testing is conducted upon symptoms of respiratory infections and with regular intervals regardless of symptomatology in sub studies. Participants provide detailed demographic and clinical data through a smart phone application-based questionnaire. Data on infection and vaccination history is collected from national registries
