Abstract

Introduction: The COVID-19 pandemic has grasped the world since late 2019. With an infectivity rate (R0) of approximately 2.5, higher than that of Influenza, SARS-CoV and MERS-CoV, and its ease of transmission through droplets, it has burdened our world with disease. COVID-19 infections produce a wide range of symptoms with the more severe symptoms presenting as complications of the disease. The increased morbidities and mortalities brought unto us by the SARS-CoV-2 virus have earned the disease the position of a public health emergency.

Aim: The purpose of this systematic review is to provide more information on the protective efficacies of cloth and surgical masks, N95, KN95, FFP2 and FFP3 respirators against SARS-CoV-2 and similar particles. A total of 8 reputable databases (PubMed, JOSTOR Journals, CINAHL, MedLINE, ERIC, ScienceDirect, Google Scholar and The Directory of Open Access Journals) have been searched for articles as guided by a set inclusion and exclusion criteria. A program was utilized to maintain a detailed record of the articles. A total of 10 articles were included in this review..

Results: Masks have been proven to reduce infection rates of COVID-19 to an extent. Cloth masks composed of different blends of fabrics, in addition to numerous layers provide the wearer with a higher level of protection as compared to a cloth mask made of one material and one layer. Surgical masks provide better protection; however, this level of protection is significantly affected by the fit of the mask, and the masks’ certification of validity (NIOSH-approved, EN 14683). N95, KN95, FFP2 and FFP3 respirators all exceed the levels of protection provided by cloth and surgical masks. These respirators provide the highest levels of protection against SARSCoV- 2.

Conclusion: Cloth masks provide some protection against SARS-CoV-2, followed by the surgical mask then by respirators. Respirators in particular have been proven to reduce the transmission of SARS-CoV-2 in high-risk healthcare settings. Despite these promising conclusions, research targeting the understanding of proper mask fit, design, quantitative fit testing for cloth and surgical masks are areas that will re-shape our understanding of mask FE.
