It is likely that the corona virus that infects humans has been present in bats' bodies for decades, but has not been detected.

A recent research has shown that the corona virus, responsible for Kovid-19 disease, was found in bats 40 and 70 years before the known virus. Scientists believe that this virus may have reached humans now.

They have said that along with this, the concept theory running on the origin of this virus has also come under suspicion that the virus was prepared in the lab or started spreading from there.

Professor David Robertson of the University of Glasgow, who worked on a research published in the journal Nature Microbiology, says the Sars-CoV2 virus responsible for the pandemic is genetically close to the virus found in bats, but both have decades of time. Is the difference.

"It means that the virus that infects humans was present for some time," he says. But we still do not know when and how it came to humans? If we believe that this is a common virus found in bats, then in this case we need a more sharp look, we have to monitor it further. ''

Professor David says that in order to not spread further epidemics in future, we will not only have to monitor the infection in humans but also have to sample wild bats. They say that if these viruses were present for decades, they must have found other animals to spread their legs, that is, to infect.

For this research, the researchers matched the genetic code of the Kovid-19 disease-causing Sars-CoV2 virus to RaTG13 found in similar bats.

Researchers found that their two ancestors are the same, but in the process of evolution, the two had separated from each other decades ago.

Professor Mark Pejal of the University of Reading is not part of this research. He says the point of this research is that the corona virus that infects humans was already present in bats 40 to 70 years ago but could not be detected.

He says, "This research shows how large the scope of infection from animals to humans is." It is possible that many viruses causing disease in humans are present in the body of the animal but we do not know about them.

These viruses may have spread from one animal to another, and they have infected people associated with the business of wild animals.

Earlier research showed that pangolin may have a major role in the origin of Sars-CoV2, but according to recent research it is not.

It may be that Pangolin also got the virus from contact with other animals during the occupation of wild animals.

American biotech company Moderna has said that the results obtained during the experiment on one of their corona virus vaccines.

Moderna said that the vaccine protects against lung and nasal infections and prevents lung disease.

On Monday, the company also started a test on humans, with 30,000 volunteers attending.

The company has been funded by the US government under a special program of one billion dollars.

Under this program named Operation Warp Speed, many efforts are being made to make the vaccine for corona virus.

Bangladesh has approved the third phase trial of China's Synovac Biotech vaccine on its citizens. Bangladesh is the country with the highest mass density in South Asia and corona infection is increasing rapidly here.

Synovac was searching for people from outside China to be tried on them. The third phase trial of Synovac in Bangladesh has also been confirmed by a member of a committee on Kovid 19. The International Center for Disease Research Bangladesh has said that its trial will start from next month.

Bangladesh Medical Research Council director Mahmood Jahan told the news agency Reuters, "We have given China in principle permission after reviewing the research protocol. 4,200 people will apply to join the trial and half of them will be vaccinated. The trial will be done in seven Kovid 19 hospitals in Dhaka.

There are currently 204,525 cases of corona in Bangladesh and close to three thousand people have died.

Synovac is also going to trial the third phase in Brazil this week.

Oxford University has been successful in developing the corona virus vaccine.

The vaccine that Oxford University has prepared has proved to be safe on humans and has indicated an improved immune system.

This vaccine was used on 1,077 people. Experiments on these people have revealed that injections of the vaccine have produced antibodies in the body of these people who contend with the corona virus.

This experiment is being seen with considerable expectations but trials are still underway on other protective measures and larger groups.

However, the British government has ordered 100 million doses of this vaccine.

Is the mutation in the virus making it more dangerous? The corona virus which has caused havoc all over the world at this time, but it is not the koranavirus that first emerged from China.

Officially known as Sars-CoV-2, the virus, which is infecting people around the world, is mutating.

Being mutated means a change in the genetic material of the virus. Scientists have seen thousands of mutations in this virus. However, there is only one mutation that indicates a change in behavior of this virus.

So can this mutation make the virus more dangerous and fatal? Does the success of the vaccine with which we are expecting also threaten it?

Scientists have observed a mutation called D614G which is present in the 'spike' of the virus and with which the virus enters our cells.

After spreading in the Chinese city of Wuhan, it is estimated that this mutation of the virus was found in Italy. The same mutation is now found in 97 percent of the world's sample.

A joint study of researchers from IIT Bhubaneswar and AIIMS has shown that corona infection in India will increase more rapidly during the monsoon and winter seasons.

In this study, it is said that the fall in temperature due to rain and cold weather in winter will be favorable for the spread of Covid 19. The study has been conducted under the leadership of Assistant Professor V Vinoj of the School of Earth, Ocean and Climate Science at IIT Bhubaneswar.

The title of the report of this study is "Covid-19 Spread in India and its dependence on Temperature and Relative Humidity". This study has also seen the pattern of outbreak of corona infection in 28 states. Vinoz has stated that the rise in temperature slows the rate of infection.

This study has not been published yet. According to the news agency PTI, the report of this study shows that temperature and related humidity is related to increased infection.

"If the temperature rises by one degree Celsius, it will help to reduce the incidence of infection by 0.99%," Vinoj told PTI.

The Indian Medical Association said on Saturday that the condition of corona virus epidemic in India is very bad. The Indian Medical Association has said that spreading of corona infection in rural areas of India is now a sign of community transmission.

Dr. VK Monga, chairman of the IMA Hospital Board of India, told news agency ANI that corona virus infection is spreading rapidly in India. Now more than 30,000 new cases are coming up every day.

Monga said, "This is a very bad situation for the country. There are many aspects related to it, but now it is spreading in rural areas. This is a very bad sign. ''

Monga warned that it would be even more difficult for the government to prevent the corona virus in towns and villages.

He said, "In Delhi we are able to prevent corona but what will happen in the remote parts of Maharashtra, Kerala, Goa and Madhya Pradesh?" State governments should prevent the health crisis from deepening with the central government. ''

The Union Health Ministry has consistently rejected community transmission of corona virus in India.

Kerala Chief Minister Pinarayi Vijayan said on Friday that community transmission has started in parts of Thiruvananthapuram.

Thiruvananthapuram was divided into three containment zones on Saturday and locked for 10 days.

Monga has said that herd immunity and vaccine are the only way to prevent the disease.

"There will be many trials and human trials for the vaccine, after which a study will be done on its effectiveness and side effects," he said.

It will also have to be seen how long the immunity developed from this will persist because not all patients are getting immunity for more than three months.

Two vaccine trials are currently underway in India. The Ethics Committee of the All India Institute of Medical Sciences (AIIMS) on Saturday approved the first indigenous vaccine for human trials of cocaine.

AIIMS will start recruiting volunteers for the vaccine trial from Monday. ZyCoV of India's second vaccine Zydus Cadila also reached the opening phase of the Human Trial this week. Clinical trials of this vaccine will be conducted in many cities in India.

The number of Corona virus infection cases in India reached 10,77,618 on Sunday. So far, 26,000 people have died in the country from Corona, while 6.7 lakh people have been recovered.

SARS-CoV-2 virus infection by mosquitoes does not spread to humans. This has been revealed in the first study on this subject. This study has been published in the journal Scientific Reports.

This study found that the virus could not increase its numbers among the three main species of mosquitoes. Therefore, even if a mosquito bites a corona infected, it cannot spread the infection to humans.

The author of this study has said, "Even in the most difficult situation, SARS does not spread through CoV-2 mosquitoes. This is not possible even if the same mosquito bites someone else after biting an infected person."

This study has also been confirmed by the World Health Organization. The World Health Organization has also cited this study as saying that the mosquito cannot be a carrier of Kovid 19 infection. However, it is still unclear what the relationship between the corona virus and the animal is?

The corona virus began to spread from Wuhan's fish market in China. It is a meat and fish market and meat of many animals was available. Some reports have also said that dogs and cats are also carriers of corona, but there is no strong evidence of this.

Balaram Bhargava, director general of the Indian Council of Medical Research, has told the media that two vaccines are underway in India regarding the corona. According to him, the use of these vaccines on rats and rabbits has been successful. Subsequently, the Drug Controller General of India has approved the human trial of these vaccines.

Bharat Biotech International Limited and Zydus Cadila are trying to make Corona vaccine in India. The vaccine name of Bharat Biotech International Limited is Covaxine.

"Now preparations are underway for human trials of both these vaccines. Both the contenders have prepared their clinical trials instead of making the vaccine. Vaccine will be used on one thousand people in both places.

During this period, Balaram Bhargava talked about the preparations for the vaccine in other countries.

He said, "Russia has accelerated the process of making its vaccines and their use has been successful in the initial stages." Work is also going on at a fast pace in China. In the United States, two vaccines are in full swing. Whereas Britain is trying to speed up the vaccine process being made at Oxford University.''

Even after recovering from the corona virus infection, there is a possibility of it coming back.

A new study has also shown that after the corona infection is cured, the immunity about the virus in the body remains for a very short time.

Scientists at King's College London are studying how the body makes antibodies to the corona virus, how many weeks and months this antibody lasts.

Antibodies found in all 96 people involved in this study were able to inhibit the corona virus. But antibody levels began to decrease over the course of three months.

However, it is not clear yet that the level of the antibody is likely to be vulnerable to the same virus. However, immunity is also short lived in common flu vegrah. In such a situation, there is a possibility of catching the same virus.

This study also showed that many times the antibodies present in the body cannot be measured, this does not mean that the body does not have immunity. Because only antibodies do not protect the body. The body also produces T cells to fight against external viruses.

This entire case still needs to be studied in detail, especially in cases where people are getting infected for the second and third time. Are they falling ill or does their body easily contend with the virus? Detailed studies can prove important to understand how effective a vaccine will be and when it will be necessary to give boosters to increase immunity.
