Coronavirus Strains: Everything You Need to Know about alpha, beta, gamma, delta, omicron


The coronavirus strains currently circulating in the world do not have the same genetic component as the coronavirus found in China’s Wuhan province by the end of 2019.

When it spreads to others, the number of coronaviruses increases, and a new line of coronavirus is inherited. Genetic mutations occur over time as each coronavirus inherits.

The nature of the coronavirus is often altered by these mutations. However, the World Health Organization (WHO) says that some genetic mutations can cause changes in the nature of the disease, reducing the dose of the corona vaccine, making it impossible to escape the corona test, and becoming drug-resistant.

A new type of coronavirus is called a ‘variant’ when it is caused by more than one genetic mutation from the previous type of coronavirus.

Although the symptoms of corona are often the same, the extent of the effects can vary.

The nature of each strain varies, including the severity of the disease. The World Health Organization will name the newly discovered corona strains according to the Greek dictionary.

The World Health Organization has named coronavirus such strains as Alpha, Beta, Gamma, Delta, Lamda, Mu, Omicron. Alpha, Beta, Gamma, Delta, and Omicron are classified as ‘variant of concern’, and Lamta and Mu as ‘variant of interest’.


Alpha strain of Coronavirus

An alpha strain of the coronavirus was first detected in the UK in September 2020.

Protein Spikes, the main component used by the coronavirus to enter the human body due to a genetic mutation caused by the alpha triple, have undergone several changes.

In a key area called the “receptor-binding domain”, the genetic mutation N501Y causes a mutation in the alpha triple.

This is the part of the virus that first interacts with human cells. If the change in this area of ​​the coronavirus can easily enter the human body, it will be a huge positive for the virus.

In alpha triplet H69 / V70 deletion, a small part of the spike is removed. It was found in a coronavirus found in an animal called a mink.

Ravi Gupta, a professor at the University of Cambridge, says that this genetic mutation doubles the spread of the virus.

The researchers said that mutations in the H69 / V70 deletion reduced the ability of antibodies, known as antibodies, to be present in the blood of people recovering from the corona.


Delta strain

This is a strain of the coronavirus discovered in India in October 2020.

The spread of this strain was a major factor in the second wave of corona that rocked India in April-May 2021.

The US Centers for Disease Control and Prevention reports that the delta-type strain of the coronavirus is more contagious than previous corona strains (alpha, beta, gamma) and is more likely to cause infection.

The report said that it was more contagious than the virus that causes SARS, Ebola, and seasonal flu.

The genetic mutation in it helps to counteract the antibodies of the immune system present in the human body.

The number of victims of this trial, also known as Delta Plus or AY.4.2, has increased following Delta.

Delta type strain, which increases the risk of infection and exacerbates the risk of hospitalization

Scientists are hopeful that the corona vaccine currently in use will work better against the Delta Plus strain as well.

Omicron strain

This new strain of coronavirus has the highest number of mutations ever found.

This new coronavirus strain is said to have 50 genetic mutations and more than 30 mutations between spike proteins.

Corona vaccines target this spike protein fiber. Similarly, the coronavirus that infiltrates the human body uses this spike protein fiber.

There are 10 mutations in the receptor that first interact with the human body. There were only two mutations in the delta triple receptors of the coronavirus that rocked the world.

The Omicron strain is milder than previous corona strains.

Numerous studies around the world have shown that omega-3s are more moderate than delta strains.

Omegran sufferers have a 30% to 70% lower risk of being hospitalized.
