Delta can be followed by a highly contagious type of corona, experts say


Every week in the United States, a group of epidemiologists sit in a virtual meeting. During this time they analyzed and discussed the different types of motility of the deadly coronavirus that have spread around the world. Trying to guess about the type of future corona. “It’s a lot like a weather report,” said William Hanagi, an epidemiologist at the world-renowned TH Chan School of Public Health at Harvard University. We have seen corona gamma, alpha type infections. But now just the corona delta type.

The first corona delta type was identified in India in December last year. This type is rapidly changing form. At the same time it spread beyond the borders of India. According to a World Health Organization (WHO) report, 99.5% of the world’s coronavirus genotypes are now delta-type.

Not just Delta, this type of corona has become more powerful in the UK. The Corona Delta Plus type has already been identified in the country. According to experts, Delta Plus is 10 to 15 percent more contagious than Delta. However, experts still do not have enough information about these. William Hanagi refers to these new types of corona as “grandchildren” of the Delta type.

However, the purpose of the weekly meetings of William Hanagi and his colleagues was to anticipate the future of the virus. Is delta the latest hypertensive type of corona? Or will something new come up after that? Will the world witness any more horrible type of corona? Epidemiologists, including William Hanagi, are trying to find answers to these questions.

There are a lot of questions here. But so far no one was able to send in the perfect solution, which is not strange. However, they say that the faster the alpha type of corona changes, the more genetic mutations occur, the slower the speed of delta change. Corona vaccination rates are rising in many parts of the world. That’s one reason. However, a more powerful type of delta may reduce the effectiveness of the current vaccine. Although it will take a long time. However, these experts only predict.

Francois Baloux, director of the Institute of Genetics at University College London (UCL), said: In the case of viruses like influenza, such changes have taken about 10 years.

But the sudden discovery of a new strain of the virus and its ability to spread very quickly raises concerns, says Ravi Gupta, a professor of clinical microbiology at Cambridge University. He said that this type of virus can be called ‘superveriant’. Analyzing the current corona situation like Ravi Gupta, ‘In the future we will see another super type of corona. Now the question is, when is that? ‘

In this regard, Ravi Gupta said, now the corona delta epidemic is seen. There are mainly two variants of this type (Delta and Delta Plus). Another new type of corona could emerge as a global challenge in the next two years. It is also likely to outperform the Delta in terms of transmission.

When will the ‘superveriant’ meet?

In the second half of 2020 (July-December), epidemiologists observed alarming signs of genetic mutations in the coronavirus around the world. A completely new type of deadly virus emerges through a gradual transformation of the genetic mutation. According to Ravi Gupta, the current transformation of the corona is not very common. Rather, it could serve as a source for a new superior variant. Especially in those parts of the world where vaccination rates are relatively low. Infection can spread rapidly in those places.

Another factor is that in the future, large-scale genetic mutations in the coronavirus could lead to a more advanced or stronger form of the current delta type. Or a completely new kind of debut is being feared. Gideon Sereiber, a professor of bio-molecular science at Israel’s Weizmann Institute of Science, said that although the current version is a delta version, there is a strong possibility of a larger version of the coronavirus in the future. The virus can be genetically modified in many places at once. This can create even bigger problems.

Recently, there has been a lot of discussion about the treatment of coronary heart disease. The use of these pills has been approved by the UK Drug Administration. Later, Bangladesh also approved the use of this drug. Experts claim that the drug ‘Malnupiravir’ halves the risk of death and hospitalization of patients infected with corona.

Mark, an American pharmaceutical company, first tested the efficacy of Malnupiravir. The company will soon apply to the Food and Drug Administration (FDA) of the United States for emergency use of Corona as a drug. According to Mark, these pills will reduce the ability of the human body to spread the coronavirus.

As these pills are anti-viral or anti-viral, they prevent the reproduction of coronavirus in the body. The virus mutates genetically until it loses its ability to reproduce. Some virus experts say that if any of these viral mutants survive and spread to others, they could create new strains.

According to Ravi Gupta, this is creating a frightening danger, which could create the risk of a new super variant of Corona spreading. This brand new type can be more contagious than the previous ones. This may raise questions about the effectiveness of conventional vaccines against corona.

Supervisors and vaccines

Epidemiologists are still trying to figure out what the new corona might be like. Major mutations in the virus have greatly increased its infectivity. For this reason, the rate of infection in the delta is relatively higher than other types of corona. Symptoms appear two to three days earlier than in early coronary heart disease.

But the hope is that the vaccine has been created with such a transformation of Corona in mind. Experts do not want Corona to come up with a superior variant that would completely ruin the effectiveness of the vaccine. The achievements of the last two years in controlling the epidemic will fade.

Corona has already developed a second generation vaccine. Vaccine manufacturer NovaVax expects the vaccine to be approved in a few months. Many such vaccines are expected to hit the market by 2023. These initiatives are giving the world a glimmer of hope in the days to come to continue the fight against Corona’s superior.

Karin Jose, executive vice president of Gretstone, a US pharmaceutical company, said a first-stage clinical trial of a second-generation coronavirus vaccine had been conducted. This vaccine will be effective against all types of the virus. However, experts think that just relying on ticks should not work.

In this regard, Ravi Gupta said that in some cases restrictions may be maintained to prevent the spread of coronavirus and to limit its chances of new transmission.

At present, corona detection rates are rising again in Europe. The number of patients is increasing every day. The role behind this is Delta type. In such cases it is important to prevent infection. So in crowded places you should avoid walking without a mask. Public health experts say new and more contagious strains of corona have been found in populated countries such as the United Kingdom, India, and Brazil, which have shown relatively low awareness of the corona. From Singapore or South Korea, however, did not spread the new type. The reason for this must be understood.
