Scientists are working hard day after day, when the world trembles with the forensic epidemic, scientists are showing hope and the world is looking for its success, and they are investigating everything we know about the coronavirus or Covid-1. 6 months passed and how much did T know that “they have to learn as much as enough to prevent the disease?” The Guardian, the British media have highlighted in a report answering these questions.
The Guardian reports that coronaviruses have caused problems for humans for a long time. The Sars and Mars viruses also belonged to this tribe. The SARS-Cove-2 virus is closely related to the two viruses: SARS and MARS. However, its impact was much less than that of pestilence-causing Covid-I. The virus has caused the blocking situation in many countries of the world in a few months. According to Johns Hopkins University, in the world Corona has died in total 1 lakh 5 thousand 5. And so far the number of identities is 1 lakh 5 thousand 5. The virus is still spreading.
Extreme achievement for the coronavirus in this slimy ball of genetic material coated in fatty chemicals called lipids. This small invasive virus has cast doubt on human potential. On the other hand, it is also worth mentioning our knowledge of the CURS-Cove-2 virus that causes Covid-1. Scientists had no information about the virus until just six months ago. Extensive research is ongoing today. The vaccine project is on the rise, antivirus drug screening tests have been launched, and new detection methods are being worked on. But the direct question is: what have we learned in the last 6 months and how can they be used to face this epidemic?
Where you come from
We can first know where the deadly virus came from. According to the Guardian report, investigators discovered that the SARS-Cove-2 virus originated from a source of bats. It has made the virus more powerful in its fight against the immune system. This immune system helps the virus to replicate or clone itself, losing the ability of the immune system to bite. As a result, bats reproduce rapidly and become a highly contagious source of the virus. When bats come in contact with other mammals and do not have a fast immune system, the virus spreads quickly and protects them. Most of the evidence suggests that the virus is transmitted to a human body through an intermediate species, such as the pangolin.
Professor Edward Holmes, a virologist at the University of Sydney, says: “The virus probably came from bats to another animal, and another animal probably went to humans, probably to the market. If a wild animal gets the bat virus , and the moving animal will become infected. When it gets home, it will infect others. This is how the epidemic spreads.
The same can happen with SARS-Cove-2 infection. When an infected person comes out of a droplet by sneezing or coughing, others become infected.
How does the virus infect humans?
Jonathan Ball, professor of virology at the University of Nottingham, UK, says that when inhaled, virus particles enter the respiratory tract and come in contact with the lining of throat and throat cells. The surface of these cells contains many specific parts of the signal called ‘A-2 receptors’. Cellular receptors play a key role in the transport of chemicals and act as a signal current within the cell. The protein contained in the virus is bound to that receptor and the RNA is inserted into the cell. Once inserted into the cell, it engages in the cell’s own replication system and generates multiple transcripts of the virus. It bursts out of the cell and spreads the infection. Antibodies that make up the immune system attack the virus and block its progression.
Experts Jonathan Ball says: “Covid-1 infections are usually mild. This is the secret of the virus’s success. Many people cannot even get the infection. They then go out and transmit the infection to others within the home. Serious coronavirus, on the other hand, makes the patient sick immediately and can cause death in one in four. In most cases, the patient should be taken to the hospital to reduce the risk of infection. In the case of mild quid-1, this cannot be assumed.
Why does death occur on Covid-1?
Although the coronavirus is mild, it sometimes causes many problems. The real complication is when the coronavirus leaves the airways and becomes infected with the lungs. Because there are more ‘A-2 receptors’ in the lungs. Many cells in the lungs are destroyed. The lungs begin to fill the broken cells. In this case, the patient needs intensive care or intensive care (ICU). Worse yet, inflammation occurs in the lungs. During this time, many immune cells spread the virus called cytokine flux. In Greek, cyto means cellular and kino means moving. In many cases, this causes the death of the patient. In some patients, the appearance of a “cytokine storm” is observed, but in most cases it is not. But why this does not happen is still unknown. One possible cause for this is the difference in the ACE-2 receptor. In some people, recipients are at high risk.
Is a healthy patient for life safe?
Doctors are examining patients recovering from a coronavirus infection. They are testing whether your body has produced enough antibodies to prevent the coronavirus. The body produces antibodies to the immune system. Antibodies reduce the cells’ ability to break down by stopping the infectious virus at a certain location.
Mike Skinner, a virologist at Imperial College London, said: “It is clear that the immune response against Covid-1 increases in those infected. Antibodies produced in response may protect against future infections. But it should be noted, this protection is not for a lifetime. “Most virologists think that the immune system against Covid-I can be effective for one to two years. According to Skinner, the same is true for other coronaviruses that transmit infections in humans. Therefore, it is likely let the disease become a seasonal disease.
The Guardian reports that the virus will remain with us for some time. However, will its capacity be reduced? Some researchers say that the coronavirus may not be as serious. But another group of researchers argue that more mutations will occur in the virus and will become more toxic. Skinner, of course, is skeptical. “The epidemic must be seen from the site of the virus,” he said. It is spreading well throughout the world. You will not be able to benefit if it changes. Finally, the development of an effective vaccine can protect the world from the threat of COVID-1.
When will the vaccine come?
As of last Friday, according to the report in the magazine ‘Nature’, five vaccine projects have been launched worldwide, of which 5 are in the development stage. The first step in the implementation of these projects is a series of programs. Work is underway on a vaccine program at Oxford University, two under the United States Biotechnology Corporation and three under the Chinese science team. Other vaccine manufacturers say they will test their application to human bodies this year.
The Guardian report says it appears that a quick effort will soon be made to vaccinate against the coronavirus. However, it is important to test the efficacy and safety of the vaccine. To test whether a virus is causing harm or its side effects, thousands of people need to be tested. This is a long-term process. That is why some researchers are applying new methods to speed up the process. It is closely monitored by applying the vaccine to healthy and young people. This method is not entirely risky. But Nair Yal, a professor of bioethics at Rutgers University, says: “This method can reduce the time required for a possible vaccine test.”
Adam Finn, a professor at the University of Bristol, says: “There should be enough caution in using vaccines among young people. Many young people can jump in such experiments. But remember, it can be deadly. আমরা জানি না এটা কেন হয়। তবে, তৃতীয় ধাপের পরীক্ষা বা অনেক মানুষের ওপর ভ্যাকসিনের প্রয়োগের সম্ভাবনা এখনো কিছুটা দূরে। ওই ধারণাটি আমাদের বিবেচনা করে দেখার সময় রয়েছে। ‘
