Americans are increasingly spurred on by wearing face masks in public amidst the coronavirus pandemic, as people around the world are.
Soon, the Centers for Disease Control and Prevention (CDC) can advise all Americans to cover their faces when they leave the house, the Washington Post reported.
The agency weighs that recommendation after they first told Americans not to wear masks and that nothing but a high-grade N medical mask would do anything to prevent infection.
FACE MASKS HELP FIRFILE INFECTION – BUT YOU'RE NOT ALL CREATED EQUAL
Research into how well different types of masks and face coverings differ, but, recently, and in the light of COVID-19's pandemic, experts are increasingly attracting to the idea that something is better than nothing.
A study by the University of Oxford published on March 30 concluded that surgical masks are just as effective in preventing respiratory infections as N95 masks for doctors, nurses and other healthcare professionals.
It is too early for them to have reliable data on how well they prevent COVID-19 infection, but the study found that thinner, cheaper masks work in flu outbreaks.
The difference between surgical as face masks and N95 masks lies in the size of particles that – and more importantly, can't – get though the materials.
N95 respirators are made of thick, tight weave and molded material that fits tightly across the face and 95 percent of all particles with air can stop, while surgical masks are thinner, looser fit and porous.
This makes surgical masks much more comfortable to breathe and work in, but less effective at injecting small particles into your mouth and nose.
Droplets of saliva and mucus from coughs and sneezes are very small, and viral particles themselves are especially small – in fact, they are about 20 times smaller than bacteria.
For this reason, a JAMA study published this month still published that people without symptoms should not wear surgical masks, because there is no evidence that the joint will protect them from infection – although they can protect people 39; coughing and sneezing infect others.
But the Oxford analysis of past studies – which has not yet been peer reviewed – found that surgical masks were wearable and did not provide statistically less protection than N95 for healthcare workers around flu patients.
However, each face mask is only as good as other health and hygiene practices. Experts agree that there is simply no substitute for thorough, often hand-washing to prevent disease transmission.
Some think the masks can also help train & # 39; people & # 39; not to touch their faces, while others claim that the unknown dress will just do more people, and in fact increase the risk of infection.
If the CDC instructs Americans to wear masks, it could create a second issue: Hospitals already lack masks and other PPEs.
WHAT TO USE TO COVER YOUR FACE IF YOU JUST HAVE MASK
That the agency may recommend that regular citizens use alternatives such as cloth masks or bandanas.
& # 39; Homemade masks could theoretically offer some protection if the materials and fit were optimized, but this is not certain, & # 39; told Dr. Jeffrey Duchin, a health & safety officer in Seattle at & # 39; a Washington Post.
A 2013 study found that in addition to a surgical mask, a vacuum cleaner bag provided the best material for a homemade mask.
After a vacuum bag, kitchen towels were quite protective, but uncomfortable. Masks made of T-shirts were very tolerable, but only worked a third as a surgical mask. The researchers at Cambridge University concluded that homemade masks only & # 39; as a last resort & # 39; should be used.
But in order for the pandemic to spread to more than 164,000 people worldwide, it may be time to consider last resort options.
