The face mask – its role in prevention of COVID-19

Abstract

The novel coronavirus disease (COVID-19) is causing huge morbidity and

mortality throughout the world. Wearing face masks is an important

strategy for its prevention, along with hand washing, using alcohol-based

sanitizer and physical distancing. In the absence of AGPs (Aerosol

Generating Procedures), health workers providing direct care to COVID-19

patients should wear a medical mask. In settings where AGPs are

performed (e.g. COVID-19 intensive and semi-intensive care units), health

workers should wear respirator masks (N95 or FFP2 or FFP3 standard).

Respirators can be reused up to five times assuming there is no soiling and

minimal to no viral contamination of the mask. Cloth face masks are

advised in public settings. It is crucial to wear, remove and dispose of masks

appropriately for maximum protection. With disposable masks becoming

an impending threat to nature, reusable LEAF masks with long lasting

filters offer a promising solution to protect our environment.
