What this Trial Is About
This research aims to compare how well air surveillance detects viruses in homes and to understand how respiratory infections like influenza and COVID-19 spread among household members. It focuses on students with acute respiratory infections and their families to see if airborne virus detection relates to the spread of illness within the home and how illness severity affects school absenteeism. Participants will collect nasal swabs while an indoor air quality monitor, called the InBio Apollo ambient air sampler, will be placed in their homes to collect airborne particles throughout the study period. The study will track symptoms and virus detection at multiple time points to evaluate the relationship between nasal and air sample results and household transmission. During the study, participants will complete surveys about their symptoms and the use of the air sampler on days 0, 7, and 14. Researchers will monitor virus detection rates, symptom changes, and the number of absences over two weeks. The study involves detailed observation of air samples and nasal swabs to better understand respiratory disease spread within households over about 14 days.
