Between the visor, the neck visor, and the goggles, the protective options are increasingly more complex. Which veil setup provides the best protection against viruses?

There is a lot of outstanding news this week. A study from Duke looked at the effectiveness of a variety of covers and led to headlines like this one The washington posts: Researchers found: “Wearing a neck coat can be worse than not wearing a mask.”

Neck-lovers – tubes that you put over your head and pull over your nose and mouth – have been raised in their arms.

Then the Philippines stipulates that you must wear a plastic face shield when going out.

One thing is clear from research: Wearing a face veil can save lives.

But there’s still a lot we don’t know yet.

The debate over who plays the classic car shows why confusion is still there.

Outdoors people often like to walk – they pull up and down easily and don’t have earcups that can pinch their ears or simply slip out.

But this week, a study from Duke concluded that wearing a car is worse than not wearing a mask for protection. (The researcher hypothesized that the gaiter’s porous structure would likely break down large COVID-19 particles into many smaller particles that could then stay in the air longer.) And the media has Post the story quickly.

Dr. Michael Edmond, an infectious disease specialist at the University of Iowa, has a few points to note about this study.

“One thing to recognize is them [tested only] Edmond said: a syrup, made of wool in the neck – a very thin type of wool. It is a synthetic material. He said: “I want to know if the tested coat is made of a different fabric with multiple layers if it needs more protection.”

In other words, he wants to see more data before he knows there is a discount all gait.

And that’s generally true about a face veil that protects others from any virus particles emitted by the wearer – and also protects the person wearing the mask.

Dr. Vicente Diaz, who specializes in eye infections and infectious diseases at Yale School of Medicine, agrees, he said while Duke’s study provides a good starting point, there are many other factors to consider. when assessing a gait – such as test circumstances and specific gait used.

“They found that when the subjects talked for ten minutes, [gaiters] seems to allow particles [spewed by the wearer] “He said,” he said: “It could be a function of the material used, as well as the design of the mask.”

Furthermore, those who exercise outdoors are … outdoors … where the risk of transmission is lower than indoors. And runners may also be following the principles of social distance, which will further reduce the risk for others – that’s why some reports have said you shouldn’t. too hurry to throw away his gait.

A ScienceNews story, by Jonathan Lambert, admits that there is really still much to be learned about the role masks play in helping to prevent the spread of COVID-19. But according to Monica Gandhi, an infectious disease expert at the University of California, San Francisco, cited in the story, “the dominance of evidence, both over the COVID-19 virus and earlier, suggests that Cloth masks and including properly worn. neck gait, filters out the majority of virus particles and provides some protection for an individual. “

Then there was a question about the plastic full-face screens.

Edmond thinks they’re pretty cool.

When it comes to larger viral droplets, he says, a face shield is more protective than a mask.

What’s more, a visor covering the eyes – a potential viral entry point – he points out. That’s something no coat or mask can do.

And while it’s easy to put on the mask improperly – let it get under your nose or hang it on your chin – that won’t happen with the face shield.

The screens are also easy to clean with a spray disinfectant, or just soap and water, Edmond says.

Again, face shields are not 100% effective either.

“Defect [with face shields] is that we don’t know how well they work to control the source, “says Edmond – in other words, limiting the spread of viral particles if you get infected.” There is another thing we are waiting for the data to actually give us the answer for. “

Therefore, Edmond says the safest approach is to incorporate masks and face shields for maximum protection from virus particles for yourself and others. He notes that when wearing a face shield in place of a mask, it can have the benefit of protecting the mask itself – preventing it from picking up virus particles.

The eye is another area to protect, if you can afford it, Diaz stressed. Studies have found that when eye protection is incorporated as part of disease control strategy, it significantly reduces the incidence of coronavirus infection, he said.

“When it comes to eyes, we know that they seem to be relevant,” Diaz said. “It is certain that the virus can get into the eyes, and about 60% of people infected with COVID have been reported to have red eyes as a symptom.”

Edmond says that wearing a visor is probably easier for most people than eye protection when it comes to eye protection. However, it depends on your preferences. If you need eye protection and don’t want to wear goggles, goggles will work. Just make sure they are actually goggles and not goggles, you can tell by they “come into pretty tight contact with your face” without the gaps.

“If fitted properly, goggles will be very protective,” he said.

Eye protection can even start with the simplest options, Diaz says – even simply choosing glasses over contact lenses could create an additional barrier. Ultimately, the best protection is something you’ll actually wear – so do as much as you can when you feel comfortable sticking consistently.

As a general rule, Diaz says it’s important to consider your own health risks when determining a masking or face masking regime. If your daily time is particularly high-risk – say you’re a health care worker – or you’re immunocompromised, “the more protection you can get, the better”.

Edmond says that he adapts his personal facial device to suit the situation.

“If I go to the grocery store, where I do not foresee that there will be people very close to me, I would normally wear a shield, unless the store specifically says I have to wear a mask,” he to speak. “But if I had to be in a classroom with lots of people per square meter – I’d probably wear a mask and a shield. And the same thing if I was on an airplane.”

Diaz follows a similar setup – wearing a surgical mask in public and incorporating N-95 / face shield at work, where he carefully observes the patient’s eyes. The best protection options, Diaz said, are a facemask with a mask that removes virus particles, or an N-95 mask, although for most people they are difficult to access.

But a mask with an exhalation valve or vents – making it easier for you to breathe – is approved by the Centers for Disease Control and Prevention. In the tutorial updated last weekend, the CDC explained that the one-way vents allow air (and therefore potentially infected respiratory particles) to escape, so the valve masks cannot prevent the transmission of COVID-19.

“To the general public, we agree that at least a cotton mask is useful,” Diaz said. “Also,” he said, “the more you do to protect yourself,” the better. “
