An update to a scientific statement issued by the Center for Disease Control (CDC) concludes that "experimental and epidemiological data" support the widespread use of face masks as a measure to reduce the spread of SARS-CoV-2, the new coronavirus that causes COVID-19 disease, the source of which is presumed to be in an exotic market in the Wuhan region of China.
According to the scientific abstract entitled: "Community Use of Masks to Control the Spread of SARS-CoV-2," "CDC recommends the widespread use of masks" as long as these do not have valves. And they recommend keeping a social distance for those who do use them because, they argue, the objective is to reduce the emission of droplets, aerosols and saliva droplets that can 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, since the valves included in some mouthpieces do not protect other people.
According to CDC data, 50% of the active cases - ambulatory cases - are apparently healthy, but that same percentage of infected persons could avoid spreading the virus by wearing a valveless mouthpiece correctly.
In addition, the CDC concludes that materials such as polypropylene used in mouthpieces "may improve their filtration efficiency" by generating "static electricity" that would help trap charged particles. And fabrics such as silk, which, they claim, "may help repel wet droplets and reduce fabric moisture" so that the mask may be gentler in terms of 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 TOT concludes by stating that "further research is needed" to sustain the basis of this research, as it can "identify combinations of materials that maximize both their blocking and filtering efficiency and their fit, comfort, durability and consumer appeal."
Finally, the CDC suggests paying attention that "the adoption of universal policies can help prevent future curfews, especially if combined with other non-pharmaceutical interventions such as social distancing, hand washing, and adequate ventilation."
