A coronavirus disease 2019 outbreak in a residential living facility with suboptimal ventilation in resident rooms - 14/09/24
Résumé |
We report a large outbreak of severe acute respiratory syndrome coronavirus 2 in a residential living facility. Measurements of carbon dioxide levels, aerosol particle clearance, and airflow were used to identify and remediate areas with suboptimal ventilation. A simple intervention involving continuous operation of bathroom fans was effective in significantly improving ventilation in resident rooms.
