Do masks mask our emotions? Not necessarily, says one expert. The United Kingdom is the latest in a long list of countries to make mask wearing mandatory to slow down the spread of Covid-19, with face coverings compulsory on public transport starting Monday. Many more of us are opting to wear a mask while shopping, meeting friends and to medical appointments — even if it’s Source 4k.
“It is a must to wear a mask!” That is presently the chant of our health department. As of the moment, surgical masks are available for the public. We limit the supply and use of n95 for healthworkers. When the pandemic broke, you can’t find n95 or surgical mask anywhere except online in excessive price. That’s how cloth mask became common. Wearing of mask protects you and the people around you.
Home-made face masks likely need at least two layers to curb COVID-19 spread. Home-made cloth face masks likely need a minimum of two layers, and preferably three, to prevent the dispersal of viral droplets from the nose and mouth that are associated with the spread of COVID-19, a new study indicates.

Effectiveness of cloth masks depends on type of covering. Wearing a mask while out in public has become the recommended practice during the COVID-19 pandemic. Researchers have now experimentally visualized the flow fields of coughs under various common mouth covering scenarios. Source 8p.
Faced with shortages, researchers combine heat and humidity to disinfect N95 masks. Researchers found that gently heating N95 masks in high relative humidity could inactivate SARS-CoV-2 virus trapped within the masks, without degrading the masks' performance. Source 9t.
The mask matters: How masks affect airflow, protection effectiveness. A computer model deepens our understanding of airflow while wearing face masks, where particles land in the respiratory tract and the effectiveness of three-layer surgical masks. Source 9c.
