Coronavirus could be slowed if everyone wore masks, says study

The Covid-19 pandemic could be halted if at least 70% of the public wore face masks invariably while stepping out, as per a review of studies which proposes that the kind of material utilized and the span of mask use assume key parts in their viability. The research, distributed in the Physics of Fluids journal, evaluated studies and analyses on face masks and inspected epidemiological reports on whether they decrease the number of people contaminated spread the pathogens to – the proliferation number of the infection. 

The scientists, including Sanjay Kumar from the National University of Singapore, stated in the study, “The highly efficacious facemask, such as surgical masks with an estimated efficacy of around 70 percent, could lead to the eradication of the pandemic if at least 70 percent of the residents use such masks in public consistently.” 

Kumar added, “Even less efficient cloth masks could also slow the spread if worn consistently.” 

As per the researchers, one key part of face mask work includes the size of liquid fluid droplets from the nose and mouth when individual talks, sings, sneezes, coughs, or even essentially breathes in front of someone. They said bigger droplets, with sizes around 5-10 microns, are the most widely common, adding that more modest droplets under 5 microns are perhaps riskier. 

 The functionality of face masks worn for a long time, for example, by frontline workers and others, demonstrate how powerful wearing a mask potentially is, the report said. 

They found that face masks made of a blend of polymer materials could channel particles at high effectiveness while at the same time cooling the face since the fibers utilized in these permit warmth to escape from underneath the mask.
