Proper fit of face masks is more important than material, study suggests
A team of researchers studying the effectiveness of different types of face masks has found that in order to provide the best protection against COVID-19, the fit of a mask is as important, or more important, than the material it is made of.
Fitting the face perfectly is a difficult technical challenge and small differences, such as a centimetre wider nose or slightly fuller cheeks, can make or break the fit of a mask Eugenia O’Kelly
The researchers, from the University of Cambridge, carried out a series of different fit tests, and found that when a high-performance mask – such as an N95, KN95 or FFP2 mask – is not properly fitted, it performs no better than a cloth mask. Minor differences in facial features, such as the amount of fat under the skin, make significant differences in how well a mask fits.
Washington [US], January 23 (ANI): A recent report published in the journal Proceedings of the Royal Society A, show that social distancing measures alone do not provide adequate protection from the virus, and further emphasise the vital importance of ventilation and face masks in order to slow the spread of COVID-19.

Scientists agree that the vast majority of Covid-19 cases are spread through indoor transmission, whether via aerosols or droplets
Researchers from the University of Cambridge and Imperial College London have quantified the role of ventilation in Covid-19 infection spread.
They have found that in poorly-ventilated spaces, the virus spreads further than two meters in seconds, and is far more likely to spread through prolonged talking than through coughing.
The results, reported in the journal Proceedings of the Royal Society A and Science Daily, revealed that social distancing measures alone do not provide adequate protection from the virus.
Researchers have developed a new online tool that can calculate the risk of COVID-19 transmission in poorly-ventilated places, showing that when two people are in such spaces and neither is wearing a mask, prolonged talking is far more likely to spread the novel coronavirus than a short cough. The research, published in the journal Proceedings of the Royal Society A, also shows that the virus spreads further than two meters in seconds in poorly-ventilated spaces. The researchers, from the University of Cambridge and Imperial College London in the UK, noted that when speaking, we exhale smaller droplets, or aerosols, which spread easily around a room, and accumulate if ventilation is not adequate.
