Although the COVID-19 disease doesn’t have a terrifying mortality rate among those that get infected, nobody can deny those over 550,000 deaths worldwide caused by it. Like frequently washing our hands, avoiding crowds as much as possible and staying away from people who sneeze, wearing a facemask in public is also among the list of measures for protecting ourselves and others from the new coronavirus.
But just how efficient these masks really are? There has been a lot of debate around the subject, and a new study led by researchers from the University of Arizona brings one more hypothesis.
In general, facemasks work
Wilson, a specialist in quantitative microbial risk assessment, says it loud and clear:
“We knew that masks work, but we wanted to know how well and compare different materials’ effects on health outcomes,”
After collecting relevant data from other studies regarding mask efficiency, a computer model was created for simulating the risk of infection. The first conclusion was that professional masks like the N95 and N99 represent the best option for protection.
Another official statement says as following:
“N99 masks, which are even more efficient at filtering airborne particles than N95 masks, are obviously one of the best options for blocking the virus, as they can reduce average risk by 94-99% for 20-minute and 30-second exposures, but they can be hard to come by, and there are ethical considerations such as leaving those available for medical professionals,”
Worldometers.info reveals that there are over 12 million cases of infected people worldwide with the new coronavirus, and 7.1 million of them had been recovered. The US remains the most infected country with more than 3.1 million infected people and over 134,000 deaths. The daily number of infections keeps rising in the States in the last days, but they must face a significant downfall at some point.
The new study regarding the facemasks was published in the Journal of Hospital Infection.
