One of the biggest challenges facing families is how to prevent further transmission of COVID-19 within the home when a loved one is infected. This is particularly important in poorer communities with low vaccination rates, smaller and more crowded houses, poor ventilation, and families working on the frontlines.
This study seeks to understand how improved ventilation and air filtration through low-cost devices in the home might help reduce spread to other family members when someone in the household is infected. Researchers are conducting a randomized controlled trial in low-income Bay Area communities to gauge the effectiveness of interventions including air filtration devices and ventilation upgrades and a ‘safer-home checklist’ in reducing SARS CoV 2 spread.
“At the heart of this work is health equity,” said Stanford Infectious Disease Fellow and Principal Investigator Abraar Karan. “Being able to bring resources into communities that face additional challenges in preventing the spread of infectious diseases in their homes is most compelling to me. Every infection prevented matters. And, if this works well, the model can be applied toward preventing other respiratory infections within the home as well.”
Karan added that this work is dedicated to his late mentor, Dr. Paul Farmer, who passed away this year. “He always pushed us to fight for the right to excellent health for all no matter where that may be or who it may be for,” Karan said.
