An update of a scientific statement published by the Center for Disease Control (CDC) concludes that "experimental and epidemiological data" support the widespread use of masks as a measure to reduce the spread of SARS-CoV-2, the new coronavirus causing COVID-19 disease, whose source is presumed to be in an exotic market in China's Wuhan region.
According to the scientific summary entitled: "Community Use of Mouthpieces to Control the Spread of SARS-CoV-2", "the CDC recommends the widespread use of mouthpieces" as long as they have no valves. And they recommend maintaining social distance for those who do use them because, they argue, the goal is to reduce the emission of droplets, aerosols and saliva drops that may be "loaded with the virus", especially if the infected person is asymptomatic or a carrier of the virus.
Valved mouthpieces do not protect other people because the valves in some mouthpieces do not protect other people.
According to CDC data, the 50% of active cases - outpatient cases - present an apparent healthy condition, however that same percentage of infected people could prevent the spread of the virus by making correct use of a valveless mouthpiece.
In addition, the CDC concludes that materials such as polypropylene used in mouthpieces "can improve their filtration efficiency" by generating "static electricity" that would help trap the charged particles. And fabrics like silk which, they say, "can help repel wet droplets and reduce fabric moisture" so the mouthpiece could be more gentle on comfort, environment, and above all, breathability; the latter being the first justification for discarding its use. The Center for Disease Control reiterates the use of the mask as a measure to control the pandemic.
The SSC concludes by stating that "further research is needed" to support the basis for this research, as it is possible to "identify combinations of materials that maximize both blocking and filtering efficiency, fit, comfort, durability and consumer appeal.
Finally, the CDC suggests paying attention that "adopting universal policies can help avoid future curfews, especially if combined with other non-pharmaceutical interventions such as social distancing, hand washing and adequate ventilation.
