Pourquoi le cuivre est le pire ennemi du coronavirus en plein air?

Le cuivre est une véritable machine à tuer les micro-organismes… Covid-19 compris. Des entreprises proposent désormais masques, gants ou poignées de porte faits de ce métal.

CORONAVIRUS – 24 heures sur du carton, 48 heures sur du plastique, plusieurs jours sur le fer… et moins de 4 heures sur du cuivre. Si l’on savait déjà que face au coronavirus, toutes les surfaces ne se valent pas, le métal rouge est d’une efficacité qui le place bien au-dessus des matières du quotidien. Des propriétés antiseptiques redoutables qui s’appliquent à tous les micro-organismes, et qui commencent pour certaines entreprises à servir d’argument marketing. 

Rien à faire, cet élément que l’on retrouve dans tant d’objets, en général sous forme d’alliage en association avec un autre métal comme du zinc ou de l’étain, est le plus fort. Non seulement contre le Covid-19, mais aussi d’autres virus, à l’image de la grippe aviaire (H1N1) ou encore du syndrome respiratoire MERS: l’effet est quasi-immédiat, fait “exploser” le micro-organisme parfois en quelques minutes seulement, pour reprendre les mots de Bill Keevil, microbiologiste à l’université de Southampton (Grande-Bretagne).

Des atomes de cuivre qui ne laissent rien passer

Virus, microbes, bactéries…le cuivre possède donc une propriété autonettoyante unique, plus encore que des métaux lourds comme l’or et l’argent, connus eux aussi pour leur capacité antiseptique. Une combativité due essentiellement à sa composition atomique: chaque atome de cuivre contient un électron libre, qui vient oxyder les molécules du micro-organisme, l’endommageant grandement. 

Même alors, le cuivre n’en a pas fini avec l’indésirable: ses ions agissent comme de véritables petits missiles, endommageant l’enveloppe de tout microbe ou autre organisme qui viendrait s’y frotter. Mis à nu, c’est ensuite au tour de l’ARN du virus de subir l’assaut mortel des électrons: après un tel traitement, il ne reste rien ou presque. Dans l’étude menée en 2015 par Bill Keevil sur un coronavirus cousin du Covid-19, il suffit ainsi de 20 minutes passées sur un alliage constitué à 95% de cuivre pour qu’une dose de liquide contagieux soit entièrement détruite. 

Cette action purificatrice du métal conducteur n’a rien de nouveau: des Phéniciens traitants les blessures de guerre au bronze, un alliage du cuivre, pour éviter les infections, jusqu’aux instruments de médecine moderne réalisés avec le même métal, cet avantage a été utilisé par de nombreuses cultures, longtemps sans pouvoir toujours être compris.

Un marché pour des entrepreneurs audacieux

Si aujourd’hui encore, les études continuent pour mieux comprendre comment le cuivre est une telle force tranquille face aux envahisseurs biologiques, l’actualité pousse les entrepreneurs à mettre en avant le cuivre comme une panacée anti Covid-19. À l’heure où le liquide antibactérien manque et où des porte-avions entiers doivent être désinfectés, l’argument marketing d’une surface autonettoyante est sans égal. 

En Australie, une société de Darwin, dans le nord du pays, propose à ses clients d’imprimer en 3D des serrures et des poignées de porte recouvertes d’un alliage de cuivre. Avec un marketing franchement audacieux, l’entreprise proclame même proposer ce service après avoir “découvert” par elle-même les propriétés antimicrobiennes du précieux métal…

Au Chili et au Japon, certaines sociétés proposent désormais des masques et des gants de protection comprenant une couche de cuivre, pour une stérilisation maximale. Même souci de ne pas transmettre le virus pour cette université texane, dont les chercheurs ont créé des autocollants en cuivre, en vente au grand public, à placer sur les poignées de porte et autres surfaces touchées quotidiennement. 

Tous ces produits, basés sur des recherches solides et des effets démontrés depuis longtemps, peuvent permettre de réduire les chances de transporter le virus d’un endroit à l’autre via un meuble ou un objet. Ils ne dispensent en aucun cas de désinfecter et nettoyer les surfaces partagées, ni évidemment, de se laver les mains fréquemment et de respecter la distanciation sociale.

8 Common Compression Wear Myths Busted

Chaussettes de cuivre avec les doigts

There has been an increase in interest in compression gear in the market. Like with all things that are trending, there are a lot of preconceived notions about compression wear.

Here are a few compression wear myths busted for you:

  1. Compression Wear is Exclusively for People With Medical Problems      Compression clothing is an excellent medical remedy for people with insufficient blood circulation. But the use of compression tights and clothing is not limited to the medical field alone.Athletes and exercise aficionados use compression gear as a part of their routine because of the same reason.
  2. Compression Gear is Only for Professional Athletes    Athletic compression socks are great for every people in every sport!Compression wear can be used pre-workout or before a game/match to increase blood flow and during a workout or sport to control muscle moment.Compression stockings can help with post-workout or post-sports soreness by increasing blood flow and helping the body get rid of toxins.
  3. Compression Clothing Renders Muscles Inactive    One of the biggest myths about compression wear is that repeated use is harmful for your muscles and renders them inactive.Compression wear helps to support your muscles and stabilize them.
  4. You Can’t Wear Compression Gear for Too Long    Another one of the compression wear myths is that you can’t wear it for too long. Wearing athletic compression socks is not dangerous but redundant if you’re not active.Compression wear is made from light, breathable fabric, which is perfect for long-term wear.
  5. Compression Clothing Works Because of the Placebo Effect    Compression wear isn’t the next big fad in the sports world without reason: it has scientifically proven effects.Wearing compression gear has medical plus points like preventing muscle inflammation, giving better muscle control and proper blood circulation.If it were just a fad, it wouldn’t be the choice for high profile athletes like Stephen Curry and Cam Newton.(Reference URL https://www.theguardian.com/lifeandstyle/2017/jun/19/under-pressure-do-compression-sports-clothes-really-improve-performance)
  6. Compression Gear is Not Fit For Warm Weather    Most compression clothing is made of a comfortable, breathable fabric. This will help control your sweat levels and regulate body temperature.Our Copper Compression Socks have the added advantage of copper. This helps keep fungi and bacterial infections at bay in humid, sweaty conditions.
  7. Compression Gear is Almost Impossible to Wear    Yes, compression clothing might be hard to put on for first timers. But once you learn to wear them with proper guidelines and get used to them, they stop being a hassle and become a part of your daily routine.

Now that we’ve busted these compression wear myths, you must have a better idea of pros of compression clothing.

Copper is a veritable machine for killing microorganisms

Copper is a veritable machine for killing microorganisms … Covid-19 included. Companies now offer masks, gloves or door handles made of this metal.
CORONAVIRUS – 24 hours on cardboard, 48 hours on plastic, several days on iron … and less than 4 hours on copper. If we already knew that facing coronavirus, not all surfaces are created equal, the red metal is so effective that it places it well above everyday materials. Terrific antiseptic properties that apply to all microorganisms, and which some companies are starting to use as a marketing argument.

Nothing to do, this element that we find in so many objects, generally in the form of alloy in association with another metal like zinc or tin, is the strongest. Not only against Covid-19, but also other viruses, such as avian flu (H1N1) or even MERS respiratory syndrome: the effect is almost immediate, sometimes “exploding” the microorganism in just a few minutes, to use the words of Bill Keevil, microbiologist at the University of Southampton (Great Britain).

Copper atoms that don’t let anything pass
Viruses, microbes, bacteria … copper therefore has a unique self-cleaning property, even more than heavy metals like gold and silver, also known for their antiseptic capacity. A combativeness mainly due to its atomic composition: each copper atom contains a free electron, which oxidizes the molecules of the micro-organism, damaging it greatly.

Even then, copper is not finished with the undesirable: its ions act like real small missiles, damaging the envelope of any microbe or other organism that comes to rub it. Once exposed, it’s the RNA’s turn to undergo the lethal onslaught of electrons: after such treatment, almost nothing remains. In the 2015 study by Bill Keevil on a coronavirus cousin to the Covid-19, it only takes 20 minutes spent on an alloy made of 95% copper for a dose of contagious liquid to be completely destroyed.

This purifying action of the conductive metal is nothing new: from the Phoenicians treating war wounds with bronze, an alloy of copper, to avoid infections, up to modern medical instruments made with the same metal, this advantage has been used by many cultures for a long time without always being understood.

A market for daring entrepreneurs
If today, studies continue to better understand how copper is such a quiet force in the face of biological invaders, current events are pushing entrepreneurs to put forward copper as an anti-Covid-19 panacea. At a time when antibacterial fluid is scarce and entire aircraft carriers need to be disinfected, the marketing argument for a self-cleaning surface is second to none.

In Australia, a company in Darwin, in the north of the country, offers its customers to 3D print locks and door handles coated with a copper alloy. With frankly audacious marketing, the company even claims to offer this service after having “discovered” for itself the antimicrobial properties of the precious metal …

In Chile and Japan, some companies now offer masks and protective gloves with a layer of copper, for maximum sterilization. Same concern not to transmit the virus for this Texan university, whose researchers have created copper stickers, for sale to the general public, to place on door handles and other surfaces touched daily.

All of these products, based on solid research and long-proven effects, can help reduce the chances of transporting the virus from one place to another via furniture or an object. They do not in any way dispense with disinfecting and cleaning shared surfaces, nor obviously, to wash your hands frequently and to respect social distancing.

Coronavirus: Chile uses the antiseptic properties of copper to make masks

Chile, the world’s leading copper producer, is betting on the antiseptic properties of this metal, which effectively eliminates bacteria, viruses and fungi, to cope with the global shortage of masks caused by the coronavirus epidemic

Bactericidal properties of copper

Two Chilean companies have thus developed models of masks to which copper nanoparticles have been added.

Because, according to several studies published by the New England Journal of medicine and the American Universities of California, Los Angeles and Princeton, the new coronavirus can survive between two and three days on plastic and stainless steel, and at least 24 hours on cardboard. However, it disappears in four hours on copper surfaces.

The Copper 3D company has launched the manufacture of reusable masks, made from a polymer into which copper nanoparticles have been injected.

These masks have a removable filter system that can be made with 3D printers, and removed for replacement.

Copper nanoparticles “destroy nucleic acids in the DNA of a virus or bacteria in a very fast and efficient process,” said Daniel Martinez, one of the project’s initiators, who is looking for funds to manufacture these masks on a large scale for an average sale price of 25 dollars each.

Chile, which supplies a third of the world’s copper production, has had the metal’s antiseptic properties certified.

In 2008, the American Environmental Protection Agency (EPA) notably approved the registration of 270 copper alloys with bactericidal properties on the contact surfaces. According to Codelco, the Chilean public mining company, copper is already used in intensive care units in hospitals, where copper-designed surfaces reduce the risk of infection by 40%. In South America , copper is also already used to make medical utensils, laboratory worktops, door handles, stair railings, etc. Another Chilean company, The Copper Company, specialized in textile, also manufactures masks, using fabrics embellished with copper nanoparticles.

“We produce between 15,000 and 20,000 fabric masks with copper nanoparticles per week and we have sold all of our production,” Luz Briceño, the company’s chief executive, told AFP.

Washable and reusable, these masks – similar in design to surgical masks – are made with certified copper wire, says Briceño, who sells her products in Chile to mining and telecommunications companies for $ 10 a unit.

The company also manufactures socks, underwear and towels with copper particles.

The World Health Organisation (WHO) Mask Management Guidance

 

For any type of mask, appropriate use and disposal are essential to ensure that they are effective and to avoid any increase in transmission.

The following information on the correct use of masks is derived from practices in health care settings.

  • Place the mask carefully, ensuring it covers the mouth and nose, and tie it securely to minimize any gaps between the face and the mask.
  • Avoid touching the mask while wearing it.
  • Remove the mask using the appropriate technique: do not touch the front of the mask but untie it from behind.
  • After removal or whenever a used mask is inadvertently touched, clean hands using an alcohol-based hand rub or soap and water if hands are visibly dirty.
    Replace masks as soon as they become damp with a new clean, dry mask.
  • Do not re-use single-use masks.
  • Discard single-use masks after each use and dispose of them immediately upon removal

Are You Safe From Coronavirus While Using Public Transport?

The Coronavirus doesn’t respect any boundaries and has a high infection rate. In the wake of the spread of the virus, hygiene in the public transports has come under scrutiny.

The transport hubs were always known to be infection hotspots. Viruses are spread largely via droplets that settle on shared surfaces. People, when they touch these contaminated surfaces contract the virus from their hands to their face and then into their system.

Planes, trains, and buses are perfect environments for viruses like Coronavirus to thrive and spread its diseases.

Pathogenic bacteria, fungi, and viruses are lurking in secrecy in the transport hubs. Some evidence:

Tubes and Trains

A research study published in BMC Infectious Diseases found that people using public transport in densely populated cities during flu outbreaks were up to six times more likely to catch an acute respiratory infection. Those most susceptible were people who commute for long hours or use busy interchange stations. This is mainly because these people come into contact with more shared surfaces than other people.

It was also found that boroughs with fewer tube stations tend to have higher infection rates, as these stops are more crowded than others.

 

 

 

 

 

 

 

 

 

Airports

In 1918, the Spanish Flu pandemic infection spread across borders through ships and ports. Today, airports are responsible for turning a local epidemic into a global pandemic.
Surprisingly, the highest risk areas in airports are security checks. The University of Nottingham and the Finnish National Institute for Health and Welfare published a study that found almost 50% of the plastic luggage trays at security checks were hotbeds for germs that can cause at least one respiratory disease such as influenza or a common cold.

These trays were found to have more germs than the airport toilets. This shouldn’t be surprising because these trays are shared by people, thousands of times over and they are seldom washed. Over time, they collect detritus from people’s belongings and pockets and are host to some of the deadliest microorganisms.

 

  1. A study published in BMC Infectious Diseases journal found the following airport areas to present a higher risk of catching a viral infection:
    • armrests of seats in the waiting area
    • chip and pin paying machines at airport pharmacies
    • handrails on escalators
  2. Buses and Trams

    In 2011, BMC Infectious Diseases conducted a study that revealed that people using buses and trams for their daily commute are exposed to almost six-fold increased risk of developing an influenza-like infection during flu season. Another study in Houston conducted in the same year found that commuters who spend more than an hour a day on the bus are eight times more likely to contract TB.

 

With Coronavirus threatening to run riot in the world, here’s how you can keep yourself safe from the scourge while travelling in public transport.

  • Coronavirus is large in size with a cell diameter of 400-500 micro. Any mask can prevent its entry into your system. So, wear masks while travelling.
  • The virus does not remain suspended in the air for long. It eventually settles down on the ground. When it falls on a metal surface such as a doorknob or handrails, it can survive for 12 hours. A simple routine of washing your hands with soap and water as soon as you reach your destination after exiting from public transport can kill the virus.
  • When Coronavirus falls on the fabric like fabric seats, clothes, etc. it remains alive for 9 hours. Being exposed to the sun for two hours or washing your clothes after your travel can kill the virus.
  • The Coronavirus lives on the hands for 10 minutes. While travelling and also otherwise, avoid touching your eyes, nose and mouth. Don’t even bite your nails. A good hand rub of an alcohol sterilizer can kill the virus. Make sure to keep a hand sanitizer in the pocket when travelling. A hand sanitizer with an alcohol content of 75%+ is more effective in killing the virus. Wearing hand gloves can also help in preventing the virus from entering your system. Copper-infused gloves can give you better protection from the virus.
  • The virus thrives in cold regions but is killed when exposed to a temperature of 26-27 ° C. So, drink hot water and be exposed to the sun whenever possible. Avoid eating ice cream and eating raw or uncooked food.
  • Avoid sitting next to a passenger who shows signs of cold, such as coughing and sneezing.
  • As a habit, check your seat before you sit down. Avoid sitting in a seat that is visibly soiled. Ask the attendant to assign another seat to you.

How Can Copper Gloves Protect You From Coronavirus

When you hold the doorknob or the subway pole with hand gloves on, the germs prevalent on the surfaces are transferred to your gloves instead of your skin. This provides temporary insulation from the live virus, bacteria or fungi. But when you touch the outside of your glove with your fingers or mouth, these organisms can travel into your system. You can prevent this from happening if you substitute your regular hand gloves with copper-infused gloves.

Copper Clothing had conducted a test that showed copper has the ability to destroy 99.9% of bacteria, fungi and viruses within minutes upon contact. How?

  • Upon contact, copper ions rupture and penetrate the cell wall.
  • Once inside the cell, the copper ions attack the microbe’s DNA, inactivating it and then eventually killing it.

Get your copper gloves now and prevent further spread of the virus!

Please Note: the 2014 test carried out by Copper Clothing using an Internationally recognised virology lab in Germany, was against Coronavirus (a family of viruses), it has not yet been tested specifically against the COVID-19 strain of the Coronavirus family.
