Universal Face Masking Reduces Respiratory Viral Infections Among Inpatient Very-Low-Birthweight Neonatal Infants.

We reviewed the impact of a universal face masking policy on respiratory viral infections (RVIs) among admitted very-low-birthweight infants in our neonatal department. There was a significant decrease in RVI incidence, specifically in our step-down level 2 unit, with respiratory syncytial virus and parainfluenza virus being the most common viruses isolated.
