| Summary: | The high-speed visualizations illustrating a flow of air when breathing and coughing using home-made face coverings. The Centers for Disease Control and Prevention recommends wearing face coverings in public settings. Since COVID-19 spreads mainly from person to person through respiratory droplets produced when an infected person coughs, sneezes or talks, a breathable well-fitting face covering may help slow the spread of the virus. Cloth face coverings are not as effective at capturing virus particles as N95 masks or surgical masks, but these should be reserved for health-care workers.
