Variants of Covid-19 continue to emerge in different regions around the world, prompting experts to question how much longer the pandemic will last and how effective current preventive measures truly are.

Since the pandemic began in late 2019, people have referred to the disease that has paralyzed the world simply as Covid-19. Now, in 2021, when we talk about Covid-19, we are not only referring to its original variant but also to countless other mutations.
In May, the WHO decided to label the main variants with Greek letters. Since then, the Delta variant has been considered the dominant and more dangerous strain, spreading more easily across the globe.
Last month, the United Kingdom was placed on high alert due to a rapidly spreading Delta variant AY.4.2. This week, Norway also announced the discovery of a new version of the Delta strain – AY.63. Experts in Norway believe it is not more dangerous than the main Delta variant. Meanwhile, another variant of Covid, identified in France (B.1.640), has astonished and unsettled researchers: “They have never seen mutations like this before.”
Professor David Dockrell from the University of Edinburgh’s Centre for Inflammation Research shared with RT that the continuous mutation of the Corona virus is a survival mechanism to evade the human immune system.
Currently, Covid-19 continues to spread despite humanity’s efforts to contain it, but Professor Dockrell offers some good news. According to him, tiny viruses like Corona can only develop to a certain extent and do not succeed as retroviruses and HIV do.
However, unfortunately, we are still in a phase where Covid-19 can continue to evolve and change. Fortunately, countries around the world have adopted various strategies to combat this disease, including vaccination efforts.
