In the COVID-19 pandemic, among the more controversial issues is the use of masks and face coverings. Much of the concern boils down to the question—just how effective are face coverings? One means to address this question is to review our understanding of the physical mechanisms by which masks and coverings operate—steric interception, inertial impaction, diffusion, and electrostatic capture. We enquire as to what extent these can be used to predict the efficacy of coverings. We combine the… Expand
How effective are face coverings in reducing transmission of COVID-19?
TLDR
It is argued from literature data on SARS-CoV-2 viral loads that the finest aerosols (< 1 micron) are unlikely to contain even a single virion in the majority of cases; masks are expected to be effective at reducing the risk of airborne transmission in most settings. Expand

Face masks play a critical role in reducing the transmission risk of COVID-19 and other respiratory diseases. Masks made with nanofibers have drawn increasingly more attention because of their higherExpand
Spatiotemporal droplet dispersion measurements demonstrate face masks reduce risks from singing: results from the COvid aNd FacEmaSkS Study (CONFESS)
TLDR
Singing during religious worship wearing a face mask appears as safe as exhaling or talking, and has implications for UK public health guidance during the COVID-19 pandemic. Expand
Statistical mechanics study of the introduction of a vaccine against COVID-19 disease.
TLDR
It is found that a high vaccination rate is required to gain control over the spread of the virus without further restrictions, and the vaccination process should be accompanied by the prevailing restrictions until most of the population is vaccinated. Expand
Using a physical model and aggregate data from Israel to estimate the current (July 2021 ) efficacy of the Pfizer-BioNTech vaccine
TLDR
A novel spatial-dynamic model finds that this new surge of cases in Israel is partiality due to a decline in the shielding of those who were vaccinated about six months ago, and a decrease in the vaccine's efficacy against severe morbidity for the early elderly population compared to the rest of the vaccinated population.

On respiratory droplets and face masks
TLDR
The study shows that the criteria employed for assessing the face mask performance must be modified to take into account the penetration dynamics of airborne droplet transmission, the fluid dynamics leakage around the filter, and reduction of efficiency during cough cycles. Expand
An evidence review of face masks against COVID-19
TLDR
An analytical framework is developed to examine mask usage, synthesizing the relevant literature to inform multiple areas: population impact, transmission characteristics, source control, wearer protection, sociological considerations, and implementation considerations. Expand
Effects of mask-wearing on the inhalability and deposition of airborne SARS-CoV-2 aerosols in human upper airway
TLDR
Investigation of the effects of wearing a surgical mask on inspiratory airflow and dosimetry of airborne, virus-laden aerosols on the face and in the respiratory tract shows that mask-wearing protects the upper airway while protecting the lungs best from particles smaller than 10 µm. Expand
Aerosol Filtration Efficiency of Common Fabrics Used in Respiratory Cloth Masks
TLDR
Overall, it is found that combinations of various commonly available fabrics used in cloth masks can potentially provide significant protection against the transmission of aerosol particles. Expand
Effectiveness of Common Fabrics to Block Aqueous Aerosols of Virus-like Nanoparticles
TLDR
Over 70 different common fabric combinations and masks were evaluated under steady-state, forced convection air flux with pulsed aerosols that simulate forceful respiration, thus avoiding artifacts including pore flooding and the loss of aerosol due to evaporation and droplet breakup. Expand
Filtration Efficiencies of Nanoscale Aerosol by Cloth Mask Materials Used to Slow the Spread of SARS-CoV-2
TLDR
The FE and ΔP increased monotonically with the number of cloth layers for a lightweight flannel, suggesting that multilayered cloth masks may offer increased protection from nanometer-sized aerosol with a maximum FE dictated by breathability (i.e., ΔP). Expand
N95 respirators, disposable procedure masks and reusable cloth face coverings: total inward leakage and filtration efficiency of materials against aerosol
TLDR
Face coverings with an enhanced level of filtration would be of benefit in circumstances where SARS-CoV-2 may be present in the aerosol of infected individuals to reduce aerosol emission from respiratory activities penetrating through into the environment. Expand
Why simple face masks are unexpectedly efficient in reducing viral aerosol transmissions
TLDR
This model shows that thin fabric masks provide protection for the wearer from aerosols expelled by another person reducing inhaled viral load by up to 20 % and 50 % and if leaks are avoided up to 35 % and 90 % for breath and speech, respectively. Expand
Filtration performances of non-medical materials as candidates for manufacturing facemasks and respirators
TLDR
Household air filters are able to achieve similar filtration efficiencies compared to the N95 material without causing a significant increase in flow resistance, and it is recommended that these filters should be inserted in multiple layers of fabrics when manufacturing facemasks or respirators.
