Geneva: The World Health Organization revealed that the delta mutant has overshadowed the three main worrisome mutations of the Corona virus in the world, which now constitute a very small percentage of the samples being examined.
“Less than one percent of the currently circulating mutant are alpha, beta and gamma,” said Maria Van Kerkhove, WHO’s technical official in charge of combating Covid-19. The delta mutant is virtually the dominant one around the world.
Van Kerkhove added, during a live meeting via social media, that Delta “has become stronger, more contagious and more competitive than other circulating viruses and replacing them,” noting that Delta has been monitored in more than 185 countries so far.
All types of viruses undergo mutation over time, such as “SARS-Cove-2”, which caused Covid-19.
And in the late 2020s, with the start of the emergence of mutations of the Corona virus that posed a greater threat, the World Health Organization classified them into interesting and worrisome mutations.
The United Nations agency decided to name the emerging mutants after the letters of the Greek alphabet to avoid stigmatizing the countries in which they first appeared.
In addition to the four worrisome mutations, there are also five different types of interest, but Van Kerkhove said three of them – eta, yuta and kappa – have been downgraded to controlled mutants.
“This is due to the change in prevalence,” she explained. “The interesting ones were outnumbered by the worrying ones. They just couldn’t stand it.”
