Can the sun’s rays destroy or eradicate the coronavirus? Experts urged the public to be more careful after a mysterious claim by a US government official.
Will hot weather slow down the disease COVID-19 caused by the new Novel Coronavirus, as it does with many other viruses such as the flu, the common cold, and pneumonia?
A new study has found that this is possible, but the effect will not be so great as to eradicate the virus or prevent the epidemic from returning in the fall.
The University of Connecticut in the United States has seen the effects of ultraviolet light, a powerful natural weapon against the new novel virus, known to damage DNA, kill viruses and infect healthy skin cells.
Researcher said we discovered that by using ultraviolet rays slow down the rate of COVID-19 disease.
However they warned that this disease will temporarily slow down during the hot season. return to autum and in next winter it will be on peak again.
However, researchers said that there is more doute about the possible result of research.
And rightly so because epidemic spread around the world, even more rapidly spread in some hot weather countries included Iran and Australia.
This research suggests that warm weather probably may help but besides this, it will also require the implementation of social distance measures.
The US National Academy of Sciences, earlier this month, after examining the effects of humidity and temperature on the virus, discovered that it had only minor effects on germs.
During a briefing Thursday by the White House Coronavirus Task Force, President Donald Trump noted the findings of the Homeland Security investigation.
According to which sunlight and antiseptic solutions such as bleach and alcohol can kill the coronavirus on the surface in 30 seconds.
Although such an idea is not yet a safe treatment, scientists have long known that the sun is a threat to many tiny germs.
Two decades ago, the British microbiologist John Postage wrote in his book, “Sunlight kills many tiny germs very quickly, due to the ultraviolet component equipped with solar radiation.”
Ultraviolet light is being used in some medical centers to disinfect face masks so that they can be reused due to the comic of protective devices during the epidemic.
However, experts say it is dangerous for humans.
Dr. Robert R. Redfield, director of the U.S. Centers for Disease Control and Prevention, said last month that he expected warmer weather to affect the disease.
“Most respiratory viruses work according to the weather, so the idea is understandable for this new virus, we have to wait, but I think most of us believe that the weather Warming up can slow down the spread of the virus.
But in another interview this week, he said the effects of the corona virus would become a problem in the fall, when the new flu season begins.
Past research reports on viruses have suggested that coronaviruses are very vulnerable to exposure to ultraviolet light due to their large genetic code.
One study found that the more target molecules a virus has, the more sunlight will damage its genome.
Other aspects of sunlight also play a role in the viruses that easily infect humans. One important thing is that sunlight produces vitamin D in the body, which is a component that strengthens the immune system and helps reduce the risk of specific diseases.
Scientists involved in the study said that although we are well aware of the effects of ultraviolet light against viruses, they were surprised to discover signs of seasonal decline globally.
He said the research team examined research reports on the effects of environmental and geological factors on the speed of disease caused by the virus and applied it to cases globally.
Seasonal trends were mapped by combining elements such as temperature, humidity, age of the population, numbers, ultraviolet rays of sunlight, and the rate of Covarna virus on a computer model.
He said the study also looked at uncertainties, such as areas in the United States where the virus rate is unlikely to drop by 20 to 40 percent in the summer.
He said that in some cases, even hot weather will not be able to provide any kind of protection, such as window glass will block ultraviolet rays, and then when someone sneezes or coughs, no kind of protection will be available.
A preliminary study by the Massachusetts Institute of Technology in the United States last month found that the rate of spread of the coronavirus in tropical communities appears to be relatively slow compared to other places.
The researchers found that areas with the highest prevalence of corona virus were those where the temperature was lower at 3 to 17 degrees Celsius.
Although cases of the corona virus have been reported in countries where the summer is currently underway, their numbers in places above 18 degrees Celsius are less than 6% of global cases.
Professor Qasim Bukhari, who is involved in the research, said that the number of cases increases rapidly where the temperature is low, you can see this trend in Europe, although the medical system there is the best in the world.
He said the temperature factor was also evident in the United States, where southern states such as Arizona, Florida and Texas were slower to spread the virus than Washington, New York and Colorado.
This effect of the weather is similar to that observed by epidemiologists in other viruses.
Scientists from Spain and Finland have discovered in a study that the virus spreads rapidly during dry environments and temperatures of 2 to 10 degrees Celsius.
A similar study in China found that before the Chinese government took aggressive measures to control the epidemic, the spread of the virus was slower in cities with high temperatures and high humidity.
But none of the research has been reviewed by other scientists, and experts at the Massachusetts Institute of Technology in the United States have acknowledged that factors such as travel restrictions, social distance measures, test availability, and hospital loads may be possibly affected the number of cases in different countries.
In fact, seasonal viruses such as influenza and seasonal flu do not disappear completely during the summer.
Rather, they are present to some extent in people’s bodies and in other parts of the world, where they wait for the right time to spread again.
The spread of the virus locally around the world also indicates that the virus could potentially be more resistant to warmer temperatures, which is why the World Health Organization (WHO) is urging countries to take immediate and aggressive action to prevent it.
MIT scientists warn that warming will slow the spread of the virus in some countries for a very short time.
But experts emphasize that a number of factors influence the spread of the virus from one person to another.
On the other hand, after surveying 224 cities across China from the beginning of January to the beginning of March, it was found that daily temperature rise or humidity does not change the rate of spread of Corona virus.
Yai Yao, head of the research team at Fudan University in Shanghai, said: “Our research does not support the idea that high temperatures and bright sunlight can slow the spread of COD-19. In fact, it is too early to say whether warm weather can control COVID-19.
However, the research team said that a number of factors could play a role in this regard, such as the natural increase in vitamin D levels in people on brighter days, which strengthens the immune system.
The sun’s ultraviolet rays also kill viruses such as the flu and the common cold, and most countries have school holidays during hot weather, which also slows the transmission of the virus.
The results of this new study have not yet been published in any medical journal and have been published on the pre-print website.
The terms and conditions of this website state that the results have not yet been reviewed and cannot be used to guide clinical practice.
