2. Facial protection for healthcare workers during pandemics: a scoping review
This study used 5462 peer-reviewed articles and 41 grey literature records.
“Conclusion: The COVID-19 pandemic has led to critical shortages of medical-grade PPE. Alternative forms of facial protection offer inferior protection. More robust evidence is required on different types of medical-grade facial protection. As research on COVID-19 advances, investigators should continue to examine the impact on alternatives of medical-grade facial protection”
So how is your cloth and surgical mask working again if EVEN medical grade alternatives are failing?
