Face Mask Construction, Materials Matter for Containing Coughing, Sneezing Droplets

While the use of face masks in public has been widely recommended by health officials during the current COVID-19 pandemic, there are relatively few specific guidelines pertaining to mask materials and designs. A study in Physics of Fluids looks to better understand which types are best for controlling respiratory droplets that could contain viruses. The team experimented with different choices in material and design to determine how well face masks block droplets as they exit the mouth.

Widespread facemask use could shrink the ‘R’ number and prevent a second COVID-19 wave – study

• Cambridge-led modelling looks at population-level facemask use.
• The more people use facemasks in public, the smaller the ‘R’.
• Even basic homemade masks significantly reduce transmission at a population level.
• Researchers call for information campaigns – “my mask protects you, your mask protects me” – that encourage the making and wearing of facemasks.

FAU Nurses Provide PPE for Homeless, Low Income Individuals During Pandemic

A team of FAU nurses is addressing the dire needs of a low income neighborhood in West Palm Beach by spearheading programs to provide lifesaving PPE such as face masks for those in need during the COVID-19 pandemic. People living in poverty as well as homeless individuals and those struggling with social determinants of health are at a higher risk of contracting COVID-19 and dying from it.

Stay 6 Feet Apart. Mechanically Simulated Cough Reveals That May Not be Enough

A preliminary, flow visualization experiment suggests that staying 6 feet apart may not be sufficient. It only took the particles from the simulated cough a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet. For a heavy cough, the particles can even travel up to 12 feet. In addition, a face mask doesn’t stop the particles 100 percent, but it does slow down the cough jets.
