Summary

This completed study looked at how the SARS-CoV-2 virus spreads within hospitals, involving over 2,000 patients, caregivers, and healthcare workers.

The goal was to improve safety for vulnerable hospitalized patients and healthcare professionals.

What this could lead to
If successful, this study could help hospitals better understand and prevent the spread of COVID-19 among patients and healthcare workers.
