COVID-19: Human Epidemiology and Response to SARS-CoV-2

The human disease caused by SARS-CoV-2 is called COVID-19. In most cases, COVID-19 presents as a mild to moderate respiratory illness. But it can also be more severe and even lead to death. The purpose of this study is to: * Determine the prevalence of SARS-CoV-2 carrier status over time in children and parents * Determine the prevalence of antibody development over time in children and parents * Compare carrier status and antibody development for children with asthma and/or other atopic conditions (e.g. eczema) versus children without asthma and/or other atopic conditions * Investigate the presence of SARS-CoV-2 exposure in historical samples from enrolled participants
