The US Center for Disease Control (CDC) has issued a statement saying that the coronavirus will not survive on the surface for much longer due to the heat. The CDC’s statement is considered important from the fast-spreading corona infection in India because many Indian areas are suffering from severe heat at this time. The figures for infection are also coming up.

The CDC (Centers for Disease Control and Prevention) says that the virus can survive on a surface for a few hours anyway, but the hot weather and strong sunlight will further reduce its survival time. The havoc of Corona continues worldwide, so far, more than three and a half million people have lost their lives, and more than 5 million have been infected. In India, more than six thousand new patients of Corona are coming out every day, and the number of patients has reached about one and a half lakh.

Even before the CDC statement, some researchers have said that the corona will be eradicated in the summer soon. Still, in India, even in the scorching heat, corona cases are increasing rather than decreasing.

In a public meeting in February, US President Donald Trump also claimed that the virus could be destroyed in the hot weather. The virus would disappear in April because the heat often eradicated such viruses. Still, nothing happened in America; the death toll from Corona has reached one lakh. Most researchers have not made authentic claims of corona being decreased due to heat, but some researchers have predicted the corona outbreak will lose its power with excess heat.

What are Researchers Saying About Temperature Variations

 

According to a China study, the weather’s rising temperature and humidity may reduce the corona’s effect. According to this study conducted by researchers from Beijing and Xinhua University in about a hundred hot cities of China, the outbreak of corona cannot be eliminated by too much heat or moisture, but its rapid spread can be curbed.

Researchers claim that as the temperature rose in a hundred Chinese cities, the average number of corona-infected patients dropped from 2.5 to 1.5. He says that Corona’s outbreak had started to decline with the weather change at one time. John Nichols, a professor of pathology at the University of Hong Kong, also believes that heat may affect corona.

Cold Weather Conditions

According to him, the virus is ‘heat-sensitive,’ and its spread may decrease during the summer season. He says that there is less risk of corona infection in places where there is too much heat.

Although today’s situation is such that no country in the world can believe any claim of China easily, researchers at the Massachusetts Institute of Technology and the University of Maryland in the US are saying something similar. According to him, 90 percent of cases of Covid-19 spread till March 22 were seen in areas where the temperature was between 3-17 degrees, and humidity was in a particular range.

The study said that hot areas like Arizona, Texas, and Florida in the US did not have the same number of cases as New York and Washington. However, the researchers also warned that their study does not mean that the coronavirus cannot spread in hot and humid areas.

Researcher Stuart Weston of the University of Maryland, School of Medicine, says he hopes that the Covid-19 shows the effect of changing weather, but it is not possible to say anything about it yet. According to a report by the National Academy of Sciences, Engineering and Medicine, environmental temperature, humidity, and the survival of the virus outside a person’s body are many other factors that affect and determine the rate of infection among humans in the real world.

Effect of Increasing Temperature Variations in the Weather

 

What and how much heat weather will affect the coronavirus? Some researchers are saying anything about it, but there is no firm evidence of what effect the rising temperature will have on the coronavirus? India’s temperature is now continuously rising and has reached around 45 degrees in North India, but instead of decreasing, the corona cases are continuously coming in large numbers.

In such a situation, it has become difficult to trust claims of corona outbreaks as temperatures rise. It is also difficult to believe these claims because, at present, cold countries like Greenland or hot cities like Dubai, all the world countries are suffering from Corona’s havoc. That is why many doctors have started saying that there is no clear evidence of whether corona’s effect will end in summer, so do not just rely on temperature.

Virologist Dr. Paresh Deshpande says that if someone sneezes in the summer season, the droplets can fall on any surface and dry quickly, which may reduce corona infection, but it will eliminate corona outbreak? It cannot be said. Many other experts believe that strong sunlight and heat may limit the coronavirus’s growth and longevity. Still, it cannot be claimed that the coronavirus will be destroyed even in severe heat.

Almost all types of viruses are inactivated or destroyed upon increasing heat. Still, in the coronavirus case, it has been observed that it survives in the human body even at 37°C. Many virologists have said that flu viruses do not remain outside the body during summer, but when it comes to corona, they didn’t say what effect of heat will be there on coronavirus, yet no one is sure about it.

Human Body Temperature Variations

However, some researchers claim that the coronavirus cannot be destroyed at temperatures from 60 to 70 degrees Celsius. If seen, this high temperature neither in most parts of the world nor within the human body. The World Health Organization has also said that we should not rely on hot temperatures to eradicate the coronavirus outbreak.

Dr. P. Raghu ram, President of The Association of Surgeons of India, is simply saying that if the coronavirus had died of heat, then the incidence of corona infection in hot countries like Australia, Singapore should have been very low. According to Dr. Michael, head of the University of Southampton, the spread of Covid-19 is faster than other viruses, and we will have to wait now to know the effect of heat on this virus.

Effect of Rising Temperature on Viruses

Of all the claims that researchers have made so far about the effect of rising temperature on the corona, one important reason is that the effect of temperature has often been seen on other viruses. Many diseases are caused by viruses, which come with the seasons’ change and disappear automatically as the weather settles.

Temperature Variations on Covid-19

In India anyway, February-March is generally considered the flu season, and the flu virus ceases as the summer heat increases. For this reason, claims have been made about the coronavirus that in the month of May-June, due to the intense heat, the corona will also end automatically. In 2002-03, an outbreak of the coronavirus called ‘SARS’ was observed in China, killing about eight hundred people.

When the scientists tested the SARS virus at that time, it was found that the virus remained active on the outer surfaces at 22-25 degrees Celsius temperature and 40-50 percent moisture in the air for five days. Still, as the temperature and air humidity increased, its activity decreased.

The outbreak of that virus, just like the corona, began to spread around November and almost ended around June-July the following year. It was said that due to increasing heat in the season, the virus was eradicated. Covid-19 also actually belongs to the family of SARS coronaviruses.

That is why some people are making similar claims like SARS. However, in this regard, British researcher Dr. Sarah Jarvis says that the SARS epidemic’s outbreak was actually due to temperature change. For some other reason, it isn’t easy to say.

On the other hand, looking at the outbreak of the virus spread in Saudi Arabia in September 2012, when that virus spread, there was a lot of heat at that time, but still, the virus spread there, and many people slept to death. This is also a major reason why scientists worldwide cannot say anything about the effect of rising temperatures on viruses like Novel Corona.

Will Covid-19 be a Local Virus?

According to scientists, ‘Covid-19’, a new member of the family of coronaviruses, has a layer of protein, and viruses with such a protein layer often have more ability to withstand the weather cycle. According to Spanish researcher Miguel Arao, the longer a virus has the ability to stay alive in the environment, the greater its risk.

It is being said about the coronavirus that it has the ability to survive for up to 28 days at 4 degrees Celsius temperature. Still, it cannot be said clearly how much and at least at what temperature it is destroyed.

Jan Albert, an expert on infectious diseases in Sweden, believes that the virus will not affect the weather. Still, if it is affected by the weather, the Covid-19 will eventually become a local virus. Some scientists believe that since laboratories’ conditions are quite different from nature, the natural seasonal cycle and variation cannot be understood based on artificially raised temperatures.

Social Distance is the Only Way to Protect

Some experts clearly state that epidemics are not usually virus-like in seasonal diseases. The Spanish flu reached its peak in the scorching heat, while many other epidemics spread during the winter season. Therefore, it is tough to say about the epidemic like corona, how the rising heat will affect the coronavirus in the coming time.

Researchers at the London School of Hygiene and Tropical Medicine say that the coronavirus has spread to every region of the world within the World Health Organization scope, including all areas that are hot, cold, and humid. It is not easy to draw a single conclusion about the effect of heat. Currently, almost all researchers believe in computer modeling and are talking based on that.

However, no matter how many claims may be made about the decrease in the spread of corona in summer, virtually no scientist in the world has any definitive answer to the effect of severe heat temperature on the corona. The reality so far regarding corona is that once this virus has entered the human body, the way to kill it has yet been discovered. Currently, no vaccine has been prepared. Therefore, maintaining social distance is the only way to avoid it.
