Find out how people transmit COVID-19 and how to prevent transmission:
How much airborne virus does an infected person exhale?
How much virus is released into the air when an infected person breathes, talks, or sings?
How well do surgical and homemade masks block release of airborne virus?
Another goal is to gather samples that can be used to better understand how the body fights the infection.

- Identify and characterize contagious phenotype of acute respiratory infection (ARI)
- Identify biomarkers of infection and contagiousness
- Test wearable sensors for early detection of ARI & outbreaks
- Collect PBMCs for identification of epigenetic markers of infection
- Characterize the role of aerosols and built environment in ARI transmission
Description of Effort:
- Enroll a longitudinal cohort and obtain baseline serology
- Identify index cases of ARI using 45plex TAC assay & enroll contacts
- Follow contacts with daily respiratory swabs and blood samples
- Characterize viral shedding in resp. & fomite swabs, and exhaled breath
- Confirm transmission events through phylogenetics sequencing
- Monitor indoor environment CO2, temperature, rel. humidity, and estimate re-breathed air exposures
- Analyze peripheral blood via RNA sequencing from days before onset of infection for biomarkers of infection and contagiousness
