Special radiation can kill COVID-19 and polio virus, Israeli study shows

A special form of radiation known as millimeter waves can kill 99% of corona and polioviruses from surfaces within two seconds, new research from scientists at Ariel University has shown. The results can have important implications on how to disinfect environments and equipment in a fast and efficient way.

“Our laboratory focuses on electromagnetic radiation sources,” said Prof. Moshe Einat from the Department of Electrical Engineering, and a co-author of the study recently published in the journal Environmental Chemistry Letters. “This type of radiation operates in the millimeter-wave regime, which means that they have a wavelength of about three millimeters. Just for comparison, the radiation from a cellphone has a wavelength of about 30 centimeters, and that from a microwave of about 12 centimeters.”

Millimeters waves have many applications. In the medical field, preliminary research has shown that they can be very effective in targeting tumors and killing cancerous cells. In addition, they can be used to transfer energy and electricity without using wires, as well as in the manufacturing process of unique materials such as synthetic diamonds.

“They make the process go much faster than the current ones,” Einat said.

After the coronavirus pandemic broke out, Einat and his team had the idea to use the waves to kill the virus, and they started cooperating with Dr. Gabi Gerlitz, a molecular biologist.

“We saw that the radiation could increase the temperature of the vials and therefore kill the virus,” said Garlitz, lead author of the study.

It does not appear that the technology can currently target the virus in the human body, “but it can be very useful for rooms, equipment and all forms of surfaces that need to be clear from any virus and coronavirus specifically,” he noted.

According to Garlitz, the big advantage offered by millimeter waves is that they can disinfect a surface very fast.

“Other methods currently used for this purpose, like UV radiation, take minutes and sometimes even a full hour, and in addition, they might be toxic for humans, which makes the disinfection process very impractical,” he said. “With our technique, we have cleared almost 99.9% of the virus within two seconds.”

The radiation is also very gentle on the surfaces, neither heating them nor affecting them, and therefore can be used on delicate surfaces such as electronic equipment.

The scientists also tried the same technology with the poliovirus and obtained similar results.

“We wanted to prove that the method works with viruses in general,” Garlitz said.

For the future, the researchers are focusing on applying the technique to disinfect water.

“Water contamination is a worldwide problem,” said Garlitz. “We think that this could offer a solution for it.”

Fauci says polio would still exist in the US if the “false information” currently being spread existed decades ago

Asked by CNN’s Jim Acosta about the misinformation spread by Fox News regarding the Covid-19 vaccines, Fauci said, “We probably would still have polio in this country if we had the kind of false information that’s being spread now.”

He added, “If we had that back decades ago, I would be certain that we’d still have polio in this country.”

The statement comes as dangerous falsehoods about Covid-19 vaccines are swirling and as health experts warn of the more transmissible Delta variant’s increasing spread among unvaccinated Americans.
Nationwide vaccination rates are dropping, while in 46 states, the rates of new Covid cases this past week are at least 10% higher than the rates of new cases the previous week, according to data from Johns Hopkins University.
Fauci, the director of the National Institute of Allergy and Infectious Diseases, told Acosta the vaccines are shown to be “highly effective in preventing symptomatic, clinically apparent disease.”
Yet less than half of the US population — 48.5%, per the latest data from the US Centers for Disease Control and Prevention — are fully vaccinated. And it’s the communities with lower vaccination rates that are at risk.
“Despite the rise of the Delta variant, still 97% of people who are hospitalized or killed by this virus are unvaccinated,” said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital in Philadelphia and a member of the US Food and Drug Administration’s vaccine advisory committee. “If the Delta variant were escaping, essentially, immunity induced by vaccination, then you should have seen a rise in people who are vaccinated, but nonetheless were still hospitalized and killed. And that hasn’t happened.”
Among those states that have fully vaccinated less than half of their residents, the average Covid-19 case rate was 11 new cases per 100,000 people last week, compared to 4 per 100,000 among states that have fully vaccinated more than half of their residents, according to a CNN analysis of data from Johns Hopkins University.

“If you look at the extraordinary success in eradicating smallpox and eliminating polio for most of the world — and we’re on the brink of eradicating polio — if we had had the pushback for vaccines the way we’re seeing on certain media, I don’t think it would’ve been possible at all to not only eradicate smallpox, we probably would still have smallpox,” said Fauci.

Polio once was a common virus. In some young children it can affect the nerves and cause muscle weakness or paralysis. There is no treatment and no cure but getting vaccinated can prevent infection.
Just in August 2020, polio was eradicated from Africa after governments and non-profits had worked since 1996 to eliminate the virus with sustained vaccination campaigns.
Polio has now been eradicated in the Americas, Southeast Asia, Europe, most of Australasia and in Africa. Wild strains of polio circulate now in only two countries: Afghanistan and Pakistan.

The World Is Still Battling Polio. What That Warning Means for Covid-19.

PESHAWAR, Pakistan—After decades of work, polio had been wiped out almost everywhere in the world. All that was left were pockets in Afghanistan and Pakistan. Medical experts hoped 2020 would be the last year that the main form of the virus, which can permanently paralyze or cause death, posed a threat.

The coronavirus pandemic put a halt to that progress.

In March, house-to-house vaccination teams working across Pakistan were forced to stop their work because of Covid-19. As a result, polio resurged, including a mutated form of the virus. It has now been detected in samples taken from sewers in 74% of Pakistan in late 2020, up from just 13% in early 2018.

“Now the virus isn’t just in select pockets. The risk is everywhere” in the country, said Rana Safdar, the doctor in charge of Pakistan’s polio campaign.

The decadeslong battle to eradicate polio around the world is one of the most ambitious and expensive public-health campaigns in history. The mass-vaccination drive and its progress toward arresting a malady that has disabled or killed millions of people point to the success possible in the efforts to inoculate people around the world against Covid-19.

Darrell Salk, son of polio vaccine creator Jonas Salk, gets Covid-19 vaccine

The younger Salk said he rarely capitalizes on his name — but he felt this time it would make a positive difference, because now he was getting the Covid-19 vaccine.

“I publicly stepped forward so I could be vaccinated publicly and have a chance to say something because I hoped that it would make a difference,” Salk told CNN. “I hoped that if I stepped forward from back in the shadows where I usually stay, it might help some people make up their minds. If so, I will be very grateful.”

Salk received the vaccine at UW Medical Center Montlake campus in Seattle, UW Medicine spokeswoman Susan Gregg confirmed to CNN.
More than 24.6 million doses of the Covid-19 vaccine have been administered in the US, according to data published Wednesday by the Centers for Disease Control and Prevention. The state of Washington has administered 534,445 doses of the vaccine, as reported by the CDC.

Salk, who has felt fine since getting the vaccine, said he was “delighted” to get his first dose. Part of that is because he has several underlying conditions and is a high-risk patient, he said.

The other part is that he sees it as a feat of modern science. Salk has spent years as a vaccinologist studying the creation of vaccines, as well as how to manufacture and transport them.

“There’s several aspects of it that were very impressive,” Salk said. “The creation of a vaccine that’s effective and safe in less than a year is astounding. It’s an amazing thing. To develop the polio virus vaccine took seven years.”

For him, the decision to get a vaccine was obvious, both for his health and those around him.

“The chances that you will be infected with Covid-19 is so much higher than the risk associated with the vaccine,” he said. “That looks like an easy choice to me. I don’t want to risk my life, or the life of someone I love.”

However, there are people who claim the vaccine is unsafe and others who are vaccine hesitant.

Salk has a message for them.

“The takeaway is that these vaccines are safe, they’re effective and they will help us bring this pandemic under control,” he said. “You should embrace the opportunity to be vaccinated and to be part of the solution.”

Polio and Covid-19 both gripped the US

The polio epidemic gripped headlines in the US as mostly children became stricken with the crippling disease. It captured the nation’s attention and the emotion of it all is something people who lived through it in the first half of the 20th century remember vividly.

The Covid-19 pandemic has some of that same emotion, Salk said, but the trajectory of both diseases is markedly different.

“Polio arose gradually. It was a chronic disease or an endemic disease, and then became epidemic as the susceptible population grew,” Salk said. “The Covid-19 virus, on the other hand, appeared, everybody was susceptible and had no experience with it before. It spread basically like wildfire … around the world very rapidly.”

Beyond the zero-to-60 mph speed of the spread of Covid-19, the fatality rate of the virus is much higher than polio, Salk said.
Polio was known for crippling and paralyzing people, killing nearly 2,000 people yearly from 1951 to 1954, according to the CDC. As of Wednesday, Covid-19 has killed at least 428,654 people in the US since last January.

Seeing Covid-19 vaccines distributed has made Salk think of his father and how “pleased and excited he would have been to see this,” he said.

“It impressed on me the importance of the work that my father did, both stopping the epidemic with the vaccine itself, and demonstrating that you could use noninfectious agents to immunize,” Salk said. His father used a killed polio virus to create the vaccine.

Living through the Covid-19 pandemic has had a duality to it for Salk, who is both intrigued and frightened of it.

“I had this kind of push me, pull you reaction,” he said. “I was scared by it, but then I was fascinated to be able to be part of it, to see it and to live through it.”

US response to the pandemic ’embarrasses’ him

Simple acts like washing your hands, wearing a mask and avoiding crowds could have controlled the spread of Covid-19. How the US responded to the pandemic frankly embarrasses Salk, he said.

“It’s really a shame that in this country, supposedly the epitome of advanced countries, the response was, I’m sorry, bungled so badly,” he said.

“We’re now swimming upstream,” he said. “It embarrasses me that the United States is number one in problems with the Covid-19 virus, more cases than anyplace else, it’s spreading faster than anyplace else. It’s embarrassing to me that this country did not respond properly because it was not driven by the science.”

The way to get the virus under control lies in enough people getting the vaccine and Salk hopes that Americans opt to get it.

“Vaccines are safe and effective, and they should be widely used,” he said. “We will get out of this, but it will take individuals doing the proper behavior in order to get rid of it.”
