Introduction
As the world continues to grapple with the COVID-19 pandemic, the importance of wearing a face mask has become increasingly clear. However, a new study suggests that wearing the wrong type of mask could be worse than not wearing a mask at all. The study, conducted by researchers at the University of Arizona, found that certain types of masks can actually increase the risk of infection by trapping and spreading droplets of saliva and other respiratory secretions. This article will discuss the findings of the study and the implications for public health.
Wearing This Mask Could Be Worse Than No Mask, Says Study
A new study has found that wearing certain types of face masks could be worse than not wearing a mask at all. The study, conducted by researchers at the University of Arizona, looked at the effectiveness of different types of face masks in preventing the spread of the novel coronavirus.
The researchers tested the effectiveness of cloth masks, surgical masks, and N95 respirators. They found that cloth masks were the least effective, with only 44% of particles being blocked. Surgical masks were slightly better, blocking 54% of particles, while N95 respirators were the most effective, blocking 95% of particles.
However, the researchers also found that wearing a cloth mask could actually increase the risk of infection. This is because the cloth masks can become damp and create an environment where the virus can thrive. The researchers also found that wearing a surgical mask or an N95 respirator could reduce the risk of infection, but only if the mask is properly fitted and sealed.
The study’s authors concluded that wearing a cloth mask could be worse than not wearing a mask at all. They recommend that people wear a surgical mask or an N95 respirator if they are going to be in close contact with other people. They also suggest that people should wash their hands frequently and practice social distancing to reduce the risk of infection.
Carrying a face masks is without doubt one of the elementary instruments we have now in stopping the unfold of COVID-19. Over the past yr, researchers have been learning protecting face coverings, trying to totally perceive that are simplest in filtering out virus particles, analyzing each medical grade masks in addition to material. Now a brand new research warns that there’s one kind of masks that is likely to be much less efficient than preserving the virus at bay then carrying no masks in any respect: a used masks. Learn on to listen to why, and to make sure your well being and the well being of others, do not miss these Positive Indicators You’ve got Already Had Coronavirus.
By no means Put on a Used Masks, Says Examine
A research revealed Tuesday within the Physics of Fluids performed by researchers from the College of Massachusetts Lowell and California Baptist College discovered that the typical three-layer surgical masks is 65 p.c environment friendly in filtering particles within the air—when it’s new not less than. As soon as it has been used and reworn, the quantity drops to 25 p.c. They consider it has to do with the truth that masks decelerate airflow, which may make individuals extra prone to inhaling particles. If a masks is soiled, it may’t filter out these tiny droplets.
“It’s pure to assume that carrying a masks, regardless of new or outdated, ought to all the time be higher than nothing. Our outcomes present that this perception is barely true for particles bigger than 5 micrometers, however not for nice particles smaller than 2.5 micrometers,” writer Jinxiang Xi defined in an accompanying press launch.
Utilizing a pc modeling system, they examined how the three-layer surgical masks affected airflow and the way particles handed by. Moreover they checked out how and the place they landed on the face and contained in the nostril, pharynx or deep lung.
Whereas carrying a masks “considerably slows down” airflow, they “discovered that the protecting efficacy of a masks for the nasal airway decreases at decrease inhalation movement charges,” per the research.
They hope their findings will encourage well being officers to look into simpler methods for masks carrying.
“We hope public well being authorities strengthen the present preventative measures to curb COVID-19 transmission, like selecting a simpler masks, carrying it correctly for the best safety, and keep away from utilizing an excessively used or expired surgical masks,” mentioned Xi.
