Multilevel functionality of the HalloyNano coating

Introduction of natural nano plates (NNP) and natural nano tubes (NNT) to the HalloyNano coating massively increases its active inner surface, which serves as a very effective carrier for other nano particles.

In addition, due to a very unique nano structure of this Halloy filler and a competitive advantage of our HalloyFusion method, all nano particles, with targeted beneficiary activities, are successfully infused and evenly distributed throughout the entire coating mass.

Thanks to our HalloyStar formula, we also gain a critical possibility of strong chemical bonding of all selected nano particles on the inner surface of nano plates and nano tubes.

As a result, our novel agent uses nearly 300m² of inner active surface of coating applied on 1m² of printed material (!), ready to combat viruses, bacteria, molds, fungi, volatile organic compounds, allergens and odors.

And all this works 24 hours a day!

Natural nano plates (NNP) and natural nano tubes (NNT) also serve in our coating as an excellent absorber of various microbes and organic compounds, crosslinking them with active bonds on the surface of nano plates and inside the nano tubes.

All these micro elements, once in contact with our coating, are bound to it, allowing for the subsequent levels of nano activity to cause their effective elimination.
The prime task of this functionality level is to effectively block the spread of micro substances, which touch the active surface of our nano coating applied to a fabric.

And all this works 24 hours a day!

Application of nano silver, which perfectly combines with nano tubes and nano plates, resulting in completely even distribution throughout the entire coating mass, prevents bacteria and fungi from growth and multiplication on the surface of our coating.

And all this works 24 hours a day!

Application of antimicrobial ability of nano zinc oxide (nano ZnO), effectively supported by the presence of titanium dioxide (TiO2), in combination with nano tubes and nano plates, and evenly active throughout the entire coating mass, causes a very effective degradation of such microorganisms as bacteria, viruses and fungi.

But the main goal of this level of nano functionality is damage of virus proteins, due to the oxidation process, by hydroxyl radicals and superoxide anion radicals.

And all this works 24 hours a day!

By using special forms of nano TiO2, connected to and transported by nano tubes and nano plates, evenly throughout their entire mass, we are able to deliver a very active photocatalytic coating.

This HalloyStar functional layer works in all types of light and, through its exposure, produces many forms of active oxygen.

it is their action that causes oxidization / deactivation / degradation of all organic substances to the simplest, harmless compounds.

The task of this level is the oxidation and decomposition of all microbiological residues that settle on the surface of the Halloy coating and which are possibly able to survive all previous levels of functional activity, in real time.

It is obvious, that our Halloy coating is most active in daylight, strengthened by UVa and UVb radiation, as it works at both wavelengths of the UV light.

But our combination of selected nano photocatalytic components, injected into nano tubes and nano plates, and fused with nano zinc oxides and nano silver, ensures effective operation of the HalloyStar coating in any type of light.

In absolute darkness, the photocatalysis process does not occur and, for this reason, the activity of the Halloy coating decreases. Nevertheless, the other components of the coating are active and continue to operate.

Once being re-exposed to light, the Halloy coating activates itself spontaneously and the degradation / oxidation process begins again literally in a few seconds.

So, it works 24 hours a day!

The last level of protection lies in the inner fabric of the mask, which is covered with the non-ionic nano silver. This layer, working at the molecular level, blocks any microorganisms from “breathing”, by destroying their protein structure.

Thanks to this, bacteria, viruses, mold and fungi, which are exhaled by the wearer, don’t grow on the inside of the mask.

And all this works 24 hours a day!

Debate

There is a great public debate around the world about the sense of wearing protective masks in public places.

Unfortunately, for all of us, in very few areas of this pandemic has scientific and official advice appeared so inconsistent as that related to face masks. Some countries have already made wearing them compulsory, some health experts still advise against it. 

We strongly believe that – during this coronavirus pandemic – people deserve full access to the best possible information concerning their health, especially all the pros and cons of wearing protective masks.

In addition, as inventors and suppliers of face masks with unique nano functionalities, we want to help all potential buyers of our products make the best possible consumer decisions.

The protection of your health is very important to us; therefore, we have decided to publish all available articles and reports, from both paid and free sources, hoping that in this way we will contribute to a much greater objectivity of your own thinking.

Financial Times, March 29, 2020 by Michael Peel in Brussels, Mehreen Khan in London, Daniel Dombey in Madrid, Laura Pitel in Ankara yesterday

The Netherlands, Spain and Turkey question quality of face masks and tests.

Several countries in or neighbouring the EU have rejected Chinese-made coronavirus testing kits and protective equipment as substandard, raising concerns about the quality of supplies.

The Netherlands, Spain and Turkey have all claimed there have been problems with products including masks and tests, as rising confirmed cases of Covid-19 infection in Europe increase dependence on Chinese imports.

The claims come as tensions grow over what the EU’s top diplomat has branded Beijing’s use of the “politics of generosity” in a “battle of narratives” over who were the most reliable international partners in the global crisis.

The Dutch health ministry said at the weekend it was forced to recall 600,000 face masks shipped from China on March 21 after they were found to be defective.

The faults, which included the masks failing to fit the mouth and having insufficient filters, were found during inspections after some masks had already been distributed to hospitals, the government said.

Authorities said the masks, from an undisclosed source, came with a KN95 certificate which meant they should filter out at least 95 per cent of airborne particles.

“Healthcare providers have been informed and told not to use the masks,” the health ministry said in a statement. “Due to shortages, we can find ourselves in a situation where only protective equipment is available that does not meet the highest standards. This is an issue in all countries.”

Josep Borrell, EU high representative for foreign policy, blogged last week that there was a “geopolitical component” to the Covid-19 crisis, including a “struggle for influence through spinning and the ‘politics of generosity’”.

China was “sending equipment and doctors to Europe” and “aggressively pushing the message that, unlike the US, it is a responsible and reliable partner”, he said.

The Netherlands is among a growing number of European countries to receive medical equipment from China. Earlier this month, Chinese telecoms operator Huawei donated a separate delivery of 800,000 face masks to the country — the first batch of which was personally welcomed into the country by Hugo de Jonge, health minister.

In Spain, which has the world’s second highest official Covid-19 death toll after Italy, the ministry of health has said it withdrew 8,000 rapid testing kits delivered to Madrid’s regional government because of worries about inaccurate results. It also sent back an additional 50,000 testing kits that had not been distributed.

The Spanish government says the supplier, Shenzhen Bioeasy Biotechnology, will replace them with 58,000 kits to the correct specifications in the “coming days”, as part of a total planned shipment of 640,000.

Shenzhen Bioeasy has said that the problems may have been because of incorrect sample collection or use of the product.

Spain says the order is separate from a €432m purchase of medical equipment from China announced last week, which includes 5.5m tests. The Chinese embassy in Madrid also stressed that the allegedly defective Shenzhen Bioeasy tests were not part of a consignment it helped arrange.

In Turkey, the government has said that it has found an unspecified number of antigen test kits sent from China to be substandard, causing it to reject them before they were used on any patients.

Ateş Kara, a member of the Turkish government’s coronavirus scientific advisory committee, said the margin of error on the antigen tests was too high, creating the risk of false negatives.

“We wanted all the tests to be totally accurate,” he said. Mr Kara said that Turkey was happy with 350,000 rapid antibody testing kits it had also bought from China. All the tests bought by Turkey were purchased directly from private companies, rather than through the Chinese government, according to a person familiar with the matter.

The Times of Israel, February 6, 2020, by Shoshanna Solomon

Sonovia’s textiles are resistant to bacteria and fungus; firm hopes its tech will also work against viruses; has sent samples for testing to China Sonovia Ltd. uses nanotechnology to create fabrics that have been shown to be effective against bacterial and fungal infections. The firms lab in Ramat Gan (Courtesy)

An Israeli startup, Sonovia Ltd., says it may have the ability to create virus resistance masks and textiles to help combat the coronavirus by using a nanotechnology process it developed to impregnate textiles with antifungal and antibacterial chemicals.

The firm says that using a patented nanotechnology process developed at Israel’s Bar-Ilan University it has managed to create masks and protective textile equipment that have proven effective in blocking the penetration of bacteria and fungus. Now, Jason Migdal, in charge of business development at the firm, says he believes the same method could also be beneficial to halt viruses, and could be effective in helping halt the spread of the deadly coronavirus.

Migdal said the startup has sent textile samples impregnated with zinc using the same method to the Chinese Academy of Sciences in Beijing, for its lab to test the efficacy of the method against viruses.

Studies have shown that nanoparticles of zinc, silver and graphite are all viral inhibitors, Migdal told The Times of Israel in a phone interview, which is why the firm “has good reason to believe” that its process could also be useful in fighting viruses.

The Chinese lab will follow a European protocol to test the fabric’s anti-viral activity, Migdal said.

The virus that started in China has infected at least 28,000 people globally, and more than 560 have died. The World Health Organization has declared the outbreak a global emergency and has warned governments to prepare for “domestic outbreak control” if the disease were to spread in their countries.

Sonovia has developed an ultrasonic fabric finishing technology for the mechanical impregnation of zinc oxite nanoparticles — which are known to be strong anti-microbial and anti-viral agents —  into textiles in a permanent manner.

The process uses soundwaves in water that break down the zinc into nanoparticles that are formed within bubbles of air. When the bubbles explode, they create tiny jet streams of liquid that force the nanoparticles of zinc into the surface of the fabric, “for long-term durability,” Migdal said.

The impregnated textile is able to maintain its anti-pathogen activity at up to 100 washes at 75° Celsius and 65 washes at 92° Celsius, he said.

“We have demonstrated clear bactericidal activity against a broad spectrum of infections in laboratory tests,” he said. A pilot study at a European hospital showed that when the impregnated fabrics were used in protective clothing, there was a “significant reduction” of infections.

“There was less bacteria in the ears and in the mouth,” he said. Because the face masks were meant for repeated use, they “could be distributed effectively
where they are needed most in China as well as being more sustainable to the environment and the local economy,” he said.

Sonovia’s technology recently got a 2.4 million euro grant from the European Commission under the Horizon 2020 program, Migdal said.

The Ramat Gan, Israel-based firm was founded in 2013 by Shay Hershcovich and Joshua Herchcovich.

The New York Times, March 27, 2020, updated March 28, 2020, by Knvul Sheikh

Experts have started to question whether masks may offer at least some protection to healthy individuals and essential workers.

As the coronavirus pandemic rages on, experts have started to question official guidance about whether ordinary, healthy people should protect themselves with a regular surgical mask, or even a scarf.

The World Health Organization and the Centers for Disease Control and Prevention continue to state that masks don’t necessarily protect healthy individuals from getting infected as they go about their daily lives.

The official guidance continues to recommend that masks should be reserved for people who are already sick, as well as for the health workers and caregivers who must interact with infected individuals on a regular basis. Everyone else, they say, should stick to frequent hand- washing and maintaining a distance of at least 6 feet from other people to protect themselves.

But the recent surge in infections in the United States, which has put the country at the center of the epidemic, with more confirmed cases than China, Italy or any other country, means that more Americans are now at risk of getting sick. And healthy individuals, especially those with essential jobs who cannot avoid public transportation or close interaction with others, may need to start wearing masks more regularly.

“The swift increase in cases to these levels in the U.S. highlights to an even greater degree the importance of implementing and adhering to public health measures,” said Dr. Robert Atmar, an infectious disease specialist at Baylor College of Medicine.

While wearing a mask may not necessarily prevent healthy people from getting sick, and it certainly doesn’t replace important measures such as hand-washing or social distancing, it may be better than nothing, Dr. Atmar said.

There is very little data showing that flat surgical masks, in particular, have a protective effect for the general public. Masks work by stopping infected droplets spewing from the wearer’s nose or mouth, rather than stopping the acquisition of virus from others. That is why the W.H.O. and C.D.C. recommend that people already infected with the coronavirus wear masks, to protect others who may come into close contact with them.

Health workers wear masks because they interact with sick patients regularly and often have to lean close for important medical procedures, exposing themselves to higher amounts of viral particles. And if healthy individuals start stockpiling surgical masks and high-grade N95 masks, they can also make it harder for health workers to get the resources they need to help on the front lines.

But studies of influenza pandemics have shown that when high-grade N95 masks are not available, surgical masks do protect people a bit more than not wearing masks at all. And when masks are combined with hand hygiene, they help reduce the transmission of infections.

When researchers conducted systematic review of a variety of interventions used during the SARS outbreak in 2003, they found that washing hands more than 10 times daily was 55 percent effective in stopping virus transmission, while wearing a mask was actually more effective — at about 68 percent.

Wearing gloves offered about the same amount of protection as frequent hand-washing, and combining all measures — hand-washing, masks, gloves and a
protective gown — increased the intervention effectiveness to 91 percent.

With the current coronavirus, researchers are also finding that there are more asymptomatic cases than were known early on in the pandemic. Classified data from the Chinese government that was reported in the South China Morning Post indicated that up to a third of all people who tested positive for the coronavirus could have been silent carriers. Widespread testing on the Diamond Princess showed that half of the positive cases on board the cruise ship had no symptoms. And officials in Iceland, who have tested a high proportion of citizens in the country, have found similarly high percentages of asymptomatic infection.

A new report from the C.D.C., published Friday, also suggests that several residents of a nursing facility in King County, Washington, either did not have any symptoms or developed very mild symptoms only after they had been confirmed to have a coronavirus infection.

Since identifying and isolating people with infections plays a major role in breaking the chain of transmissions, people who do not have any symptoms or do not develop symptoms until later may continue to inadvertently spread the disease.

“It’s still hard to tell what percentage of people are truly asymptomatic because many go on to develop symptoms a few days later,” said Dr. Neil Fishman, the chief medical officer of the Hospital of the University of Pennsylvania. “What we do know is that individuals can shed virus about 48 hours before they develop symptoms and masking can prevent transmission from those individuals.”

Wearing a mask can also reduce the likelihood that people will touch their face, which is another mode of transmission of the virus from contaminated surfaces to unsuspecting individuals, Dr. Fishman said.

“For individuals working in certain essential industries, where they still have to go out every day, I think wearing a mask makes sense,” Dr. Fishman said.

In many Asian countries, everyone is encouraged to wear masks, and the approach is about crowd psychology and protection. If everyone wears a mask, individuals protect each other, reducing overall community transmission. The sick automatically have one on and are also more likely to adhere to keeping their mask on because the stigma of wearing one is removed.

Masks are also an important signal that it’s not business as usual during a pandemic. They serve as a visual reminder to improve hand hygiene and social distancing. They may also serve as an act of solidarity, showing that all citizens are on board with the precautionary measures needed to bring infections under control. And places like Hong Kong and Taiwan that jumped to action early with social distancing and universal mask wearing have gotten their cases under much greater control.

“If everyone in the community wears a mask, it could decrease transmission,” Dr. Fishman said. “But unfortunately I think that we don’t have enough masks to make that effective policy in the U.S.”

The Engineer, March 19, 2020

A research team in South Korea has developed a nano-filter that could extend the life of face masks being worn extensively because of coronavirus (Covid-19).

Demand for face masks in South Korea has led to the nation’s government rationing them to two per person per week. The face masks most commonly used are disposable N94 and N95 types that were made for filtering up to 95 per cent of fine dust.

A KAIST (Korea Advanced Institute of Science and Technology) research has now developed a nano-filter that is claimed to maintain filtering efficiency, even after hand washing, through the development of proprietary technology that aligns nanofibres with a diameter of 100~500nm in orthogonal or unidirectional directions. The team believe the reusable nano-filtered face mask could help relieve the challenges arising from shortages of face masks.

Professor Il-Doo Kim’s nano-fibre filtered mask is said to maintain its frame and filtering function even after being washed more than 20 times. Professor Kim, who has continued to study the filtering of fine dust using nano-filters, is now awaiting final approval from South Korea’s Ministry of Food and Drug Safety to bring his product to market.

Professor Kim used an insulation block electrospinning process to manufacture orthogonal nanofibres by controlling the alignment of nanofibres. This structure can minimise delivering of the pressure toward the air filter and maximise the filtration efficiency, which is different from existing disposable masks without nano-fibres.

According to KAIST, existing masks also fail to maintain their air filtering function because their electrostatic function disappears when exposed to water. The nano-fibre design was proven to be water-resistant with more than 94 per cent filtering efficiency in 20 repeated bactericidal tests with ethanol. The nano-filter mask also showed no deformation in its nano-membrane structure despite the 20 hand washes. In particular, it was confirmed that there were no deformations in the membrane, even after soaking in ethanol more than three hours.

“We believe that this mask can be reusable for about a month even after washing in ethanol,” Professor Kim said in a statement. “The inner filter can also be replaced. We found that the mask filters out up to 80 per cent of 600nm particles even after undergoing a bending test more than 4,000 times.”

In February Professor Kim established the Kim Il-Doo Research Institute, a start-up that currently produces 1,500 nano-filters per day.

The Israel 21c, January 28, 2020, by Abigail Klein Leichman

Two Israeli companies are rushing to complete development of facemasks that could be vital prevention tools in epidemics like Wuhan coronavirus. As the Wuhan coronavirus outbreak continues to spread, two Israeli companies are finalizing development of revolutionary antiviral reusable facemasks.

“Israel has technologies that can support controlling this epidemic,” says Liat Goldhammer-Steinberg, CTO of Sonovia in Ramat Gan.

The virus is spread by air and direct contact. The World Health Organization reports approximately 4,200 cases of infection since December 31. Most of the cases are in China. A few have been confirmed in 15 additional countries.

Because there is no vaccine or treatment for 2019-nCoV, personal protective equipment is an important way to combat the transmission of the virus and avoid a pandemic.

Disposable facemasks cannot block all pathogens and do not kill them. A used and discarded mask can even become a vector for disease as the pathogens multiply in its fibers.

That’s why washable, reusable masks with anti-pathogen properties could provide a potent prevention tool against the 2019-nCoV and other coronaviruses that have evolved into more severe illnesses, such as SARS and MERS.

Sonovia seeking partners

Sonovia’s ultrasonic fabric-finishing technology, invented by two Bar-Ilan University chemistry professors, mechanically infuses antiviral, antimicrobial zinc and copper oxide nanoparticles into textiles for facemasks and other protective products.

Sonovia recently received a European Commission Horizon 2020 grant and the technology has won several prizes in China.

Tests have shown that Sonovia’s treated textiles work against six types of bacteria including E. coli and Staph. Effectiveness lasts for up to 100 washes at 75°C (167°F) or 65 washes at 92°C (197°F). The impregnated polyester-cotton fabric has been shown effective against some strains of influenza. It has not been tested for effectiveness against the current coronavirus.

Once a lab that can do this test is identified, the process could take eight weeks, says Goldhammer-Steinberg. “We are not commercialized yet,” she stresses. “But we have a prototype machine we are willing to put into operation using treated yardage from our R&D product — if we have a partner and interest.”

Interest is not a problem: Sonovia hosted visitors from China earlier this week and is receiving “nonstop calls” following media exposure. Goldhammer-Steinberg says there is enough treated fabric available to make about 5,000 to 10,000 reusable face masks. These would not be for sale, rather for partners to distribute as an emergency measure.

“Right now, there is a shortage of supplies [in affected countries] so we could help decrease that stress. Even if there is a remote chance it could help, it is worth trying,” she tells ISRAEL21c.

“We are actively reaching out to collaborative investors and partners from around the world because we believe there is high potential for our products to save lives.”

Argaman’s Bio-Block mask

Jerusalem-based Argaman is nearing commercialization of a reusable, washable, breathable antiviral facemask called Bio-Block.

According to founder and CEO Jeff Gabbay, a textile engineer with a background in pathology and infectious diseases, Bio-Block is a layered mask.

It’s made from a proprietary cotton embedded with accelerated copper oxide particles, and a nanofiber textile that blocks pathogens.

“The pores of the nanofiber pad are so small that bacteria cannot go through it — nor a droplet that contains a live virus –and our EPA-approved 100% CottonX fibers destroy the pathogens that come in contact with it,” Gabbay says.

“The mask not only blocks the virus but kills the viruses going both to the wearer and away from the wearer in case the wearer is infected,” he explains. An independent lab found that CottonX remains effective against Staph and E. coli bacteria for 50 industrial washings or 100 home washings.

A hospital test sponsored by the US Centers for Disease Control found that CottonX bedding and gowns in the ICU reduced multi-drug resistant pathogens by 50%. This study is soon to be published, says Gabbay.

Like the Sonovia textile, CottonX has not been tested for effectiveness against the 2019-nCoV coronavirus.

The first 20,000 Bio-Block masks are in production in Argaman’s Jerusalem facility and will retail for about $50. They will be available in about two months.

An Amazon store will be opened once the masks and other protective products are ready, says Gabbay. Meanwhile, inquiries about orders can be sent to info@argamantech.com.

The Netherlands, Spain and Turkey question quality of face masks and tests.

Several countries in or neighbouring the EU have rejected Chinese-made coronavirus testing kits and protective equipment as substandard, raising concerns about the quality of supplies.

The Netherlands, Spain and Turkey have all claimed there have been problems with products including masks and tests, as rising confirmed cases of Covid-19 infection in Europe increase dependence on Chinese imports.

The claims come as tensions grow over what the EU’s top diplomat has branded Beijing’s use of the “politics of generosity” in a “battle of narratives” over who were the most reliable international partners in the global crisis.

The Dutch health ministry said at the weekend it was forced to recall 600,000 face masks shipped from China on March 21 after they were found to be defective.

The faults, which included the masks failing to fit the mouth and having insufficient filters, were found during inspections after some masks had already been distributed to hospitals, the government said.

Authorities said the masks, from an undisclosed source, came with a KN95 certificate which meant they should filter out at least 95 per cent of airborne particles.

“Healthcare providers have been informed and told not to use the masks,” the health ministry said in a statement. “Due to shortages, we can find ourselves in a situation where only protective equipment is available that does not meet the highest standards. This is an issue in all countries.”

Josep Borrell, EU high representative for foreign policy, blogged last week that there was a “geopolitical component” to the Covid-19 crisis, including a “struggle for influence through spinning and the ‘politics of generosity’”.

China was “sending equipment and doctors to Europe” and “aggressively pushing the message that, unlike the US, it is a responsible and reliable partner”, he said.

The Netherlands is among a growing number of European countries to receive medical equipment from China. Earlier this month, Chinese telecoms operator Huawei donated a separate delivery of 800,000 face masks to the country — the first batch of which was personally welcomed into the country by Hugo de Jonge, health minister.

In Spain, which has the world’s second highest official Covid-19 death toll after Italy, the ministry of health has said it withdrew 8,000 rapid testing kits delivered to Madrid’s regional government because of worries about inaccurate results. It also sent back an additional 50,000 testing kits that had not been distributed.

The Spanish government says the supplier, Shenzhen Bioeasy Biotechnology, will replace them with 58,000 kits to the correct specifications in the “coming days”, as part of a total planned shipment of 640,000.

Shenzhen Bioeasy has said that the problems may have been because of incorrect sample collection or use of the product.

Spain says the order is separate from a €432m purchase of medical equipment from China announced last week, which includes 5.5m tests. The Chinese embassy in Madrid also stressed that the allegedly defective Shenzhen Bioeasy tests were not part of a consignment it helped arrange.

In Turkey, the government has said that it has found an unspecified number of antigen test kits sent from China to be substandard, causing it to reject them before they were used on any patients.

Ateş Kara, a member of the Turkish government’s coronavirus scientific advisory committee, said the margin of error on the antigen tests was too high, creating the risk of false negatives.

“We wanted all the tests to be totally accurate,” he said. Mr Kara said that Turkey was happy with 350,000 rapid antibody testing kits it had also bought from China. All the tests bought by Turkey were purchased directly from private companies, rather than through the Chinese government, according to a person familiar with the matter.

Sonovia’s textiles are resistant to bacteria and fungus; firm hopes its tech will also work against viruses; has sent samples for testing to China Sonovia Ltd. uses nanotechnology to create fabrics that have been shown to be effective against bacterial and fungal infections. The firms lab in Ramat Gan (Courtesy)

An Israeli startup, Sonovia Ltd., says it may have the ability to create virus resistance masks and textiles to help combat the coronavirus by using a nanotechnology process it developed to impregnate textiles with antifungal and antibacterial chemicals.

The firm says that using a patented nanotechnology process developed at Israel’s Bar-Ilan University it has managed to create masks and protective textile equipment that have proven effective in blocking the penetration of bacteria and fungus. Now, Jason Migdal, in charge of business development at the firm, says he believes the same method could also be beneficial to halt viruses, and could be effective in helping halt the spread of the deadly coronavirus.

Migdal said the startup has sent textile samples impregnated with zinc using the same method to the Chinese Academy of Sciences in Beijing, for its lab to test the efficacy of the method against viruses.

Studies have shown that nanoparticles of zinc, silver and graphite are all viral inhibitors, Migdal told The Times of Israel in a phone interview, which is why the firm “has good reason to believe” that its process could also be useful in fighting viruses.

The Chinese lab will follow a European protocol to test the fabric’s anti-viral activity, Migdal said.

The virus that started in China has infected at least 28,000 people globally, and more than 560 have died. The World Health Organization has declared the outbreak a global emergency and has warned governments to prepare for “domestic outbreak control” if the disease were to spread in their countries.

Sonovia has developed an ultrasonic fabric finishing technology for the mechanical impregnation of zinc oxite nanoparticles — which are known to be strong anti-microbial and anti-viral agents —  into textiles in a permanent manner.

The process uses soundwaves in water that break down the zinc into nanoparticles that are formed within bubbles of air. When the bubbles explode, they create tiny jet streams of liquid that force the nanoparticles of zinc into the surface of the fabric, “for long-term durability,” Migdal said.

The impregnated textile is able to maintain its anti-pathogen activity at up to 100 washes at 75° Celsius and 65 washes at 92° Celsius, he said.

“We have demonstrated clear bactericidal activity against a broad spectrum of infections in laboratory tests,” he said. A pilot study at a European hospital showed that when the impregnated fabrics were used in protective clothing, there was a “significant reduction” of infections.

“There was less bacteria in the ears and in the mouth,” he said. Because the face masks were meant for repeated use, they “could be distributed effectively
where they are needed most in China as well as being more sustainable to the environment and the local economy,” he said.

Sonovia’s technology recently got a 2.4 million euro grant from the European Commission under the Horizon 2020 program, Migdal said.

The Ramat Gan, Israel-based firm was founded in 2013 by Shay Hershcovich and Joshua Herchcovich.

The New York Times, March 27, 2020, updated March 28, 2020, by Knvul Sheikh

Experts have started to question whether masks may offer at least some protection to healthy individuals and essential workers.

As the coronavirus pandemic rages on, experts have started to question official guidance about whether ordinary, healthy people should protect themselves with a regular surgical mask, or even a scarf.

The World Health Organization and the Centers for Disease Control and Prevention continue to state that masks don’t necessarily protect healthy individuals from getting infected as they go about their daily lives.

The official guidance continues to recommend that masks should be reserved for people who are already sick, as well as for the health workers and caregivers who must interact with infected individuals on a regular basis. Everyone else, they say, should stick to frequent hand- washing and maintaining a distance of at least 6 feet from other people to protect themselves.

But the recent surge in infections in the United States, which has put the country at the center of the epidemic, with more confirmed cases than China, Italy or any other country, means that more Americans are now at risk of getting sick. And healthy individuals, especially those with essential jobs who cannot avoid public transportation or close interaction with others, may need to start wearing masks more regularly.

“The swift increase in cases to these levels in the U.S. highlights to an even greater degree the importance of implementing and adhering to public health measures,” said Dr. Robert Atmar, an infectious disease specialist at Baylor College of Medicine.

While wearing a mask may not necessarily prevent healthy people from getting sick, and it certainly doesn’t replace important measures such as hand-washing or social distancing, it may be better than nothing, Dr. Atmar said.

There is very little data showing that flat surgical masks, in particular, have a protective effect for the general public. Masks work by stopping infected droplets spewing from the wearer’s nose or mouth, rather than stopping the acquisition of virus from others. That is why the W.H.O. and C.D.C. recommend that people already infected with the coronavirus wear masks, to protect others who may come into close contact with them.

Health workers wear masks because they interact with sick patients regularly and often have to lean close for important medical procedures, exposing themselves to higher amounts of viral particles. And if healthy individuals start stockpiling surgical masks and high-grade N95 masks, they can also make it harder for health workers to get the resources they need to help on the front lines.

But studies of influenza pandemics have shown that when high-grade N95 masks are not available, surgical masks do protect people a bit more than not wearing masks at all. And when masks are combined with hand hygiene, they help reduce the transmission of infections.

When researchers conducted systematic review of a variety of interventions used during the SARS outbreak in 2003, they found that washing hands more than 10 times daily was 55 percent effective in stopping virus transmission, while wearing a mask was actually more effective — at about 68 percent.

Wearing gloves offered about the same amount of protection as frequent hand-washing, and combining all measures — hand-washing, masks, gloves and a
protective gown — increased the intervention effectiveness to 91 percent.

With the current coronavirus, researchers are also finding that there are more asymptomatic cases than were known early on in the pandemic. Classified data from the Chinese government that was reported in the South China Morning Post indicated that up to a third of all people who tested positive for the coronavirus could have been silent carriers. Widespread testing on the Diamond Princess showed that half of the positive cases on board the cruise ship had no symptoms. And officials in Iceland, who have tested a high proportion of citizens in the country, have found similarly high percentages of asymptomatic infection.

A new report from the C.D.C., published Friday, also suggests that several residents of a nursing facility in King County, Washington, either did not have any symptoms or developed very mild symptoms only after they had been confirmed to have a coronavirus infection.

Since identifying and isolating people with infections plays a major role in breaking the chain of transmissions, people who do not have any symptoms or do not develop symptoms until later may continue to inadvertently spread the disease.

“It’s still hard to tell what percentage of people are truly asymptomatic because many go on to develop symptoms a few days later,” said Dr. Neil Fishman, the chief medical officer of the Hospital of the University of Pennsylvania. “What we do know is that individuals can shed virus about 48 hours before they develop symptoms and masking can prevent transmission from those individuals.”

Wearing a mask can also reduce the likelihood that people will touch their face, which is another mode of transmission of the virus from contaminated surfaces to unsuspecting individuals, Dr. Fishman said.

“For individuals working in certain essential industries, where they still have to go out every day, I think wearing a mask makes sense,” Dr. Fishman said.

In many Asian countries, everyone is encouraged to wear masks, and the approach is about crowd psychology and protection. If everyone wears a mask, individuals protect each other, reducing overall community transmission. The sick automatically have one on and are also more likely to adhere to keeping their mask on because the stigma of wearing one is removed.

Masks are also an important signal that it’s not business as usual during a pandemic. They serve as a visual reminder to improve hand hygiene and social distancing. They may also serve as an act of solidarity, showing that all citizens are on board with the precautionary measures needed to bring infections under control. And places like Hong Kong and Taiwan that jumped to action early with social distancing and universal mask wearing have gotten their cases under much greater control.

“If everyone in the community wears a mask, it could decrease transmission,” Dr. Fishman said. “But unfortunately I think that we don’t have enough masks to make that effective policy in the U.S.”
