Summary

This trial tests if using box-fans with filters and better ventilation can reduce spread of Covid19 in homes with an infected person.

Who is the study for?
This trial is for households with a confirmed case of COVID-19 and at least three other people living together. Eligible homes must not have had the positive test result more than two days ago, expect most members to be present over the next week, and can't already have half or more members likely infected.
What is being tested?
The study tests if using box-fans with high-efficiency filters alongside guidance on improving home ventilation can prevent COVID-19 from spreading to others in the same household as someone who's infected.
What are the potential side effects?
There are no direct medical side effects from participating in this trial since it involves non-invasive interventions like air filtration and ventilation rather than medications.

Group I: InterventionExperimental Treatment3 Interventions
Families are provided with one filtration fan unit per room in their home (and one for the index case; if the family lives in a studio, they would receive 2 units). Investigators will advise families on ventilation improvements in their home. Investigators will provide an instructional pamphlet that describes how the fans work and the importance of ventilation. Investigators will follow-up on day 3-4 to check in and run through a checklist to ensure the fans are working and ventilation improvements are being attempted. Investigators will give families a CO2 monitor to measure average CO2 levels in the home. Investigators will test family members at day 0-1 for baseline testing; and again on day 7 for assessing secondary transmission among susceptible contacts.
Group II: ControlActive Control1 Intervention
No intervention will be administered in this arm. Investigators will give families a CO2 monitor to measure average CO2 levels in the home. Investigators will provide a link to the basic CDC isolation guidelines which would be part of standard of care. Investigators will test family members at day 0-1 for baseline testing; and again on day 7 for assessing secondary transmission among susceptible contacts.
