Ineffective masks at reducing spread

Aug 04, 2020

Family Care Network recommends patients follow CDC guidelines for mask use to reduce the spread of COVID-19.

According to the CDC, masks with filtered valves should not be used to prevent virus spread. The valve releases unfiltered air when the wearer breathes out.

They recommend wearing a stitched-quilting fabric mask without an exhalation valve. The most protective version has two layers of material and a pocket for a filter to reduce potentially infected respiratory droplets from spreading the virus.

Additionally, Single layer fabrics like bandanas for mask use are the least effective at reducing respiratory droplets. Coughs emitted from someone wearing a bandana were found in a study by Florida Atlantic University to travel 3 feet, 7 inches compared to stitched-quilting fabric masks that allowed droplets to travel only 2.5 inches.

Social distancing and hand-washing should be used in addition to wearing a mask. If you feel sick, please stay home unless you need to seek medical care.

Children under age 2 and anyone who has trouble breathing or can’t remove a mask without assistance should NOT wear a mask.
