The “worrying” Delta mutation, which has been identified in 185 countries to date, has almost displaced the three previous “worrying” variants, Alpha, Beta and Gamma, which are now less than 1% of cases in which the genome is analyzed, informed on Tuesday (21/9) the World Health Organization (WHERE).
All viruses, including coronavirus that causes Covid-19, mutate. The emergence, at the end of 2020, of variants that posed an increased risk to public health worldwide has led the WHO to label some of them as “worrying” and others as “variants of interest” in order to prioritize their research and monitoring around the world.

“The Delta variant is more powerful and contagious”
“The prevailing variant that is being released now is Delta. “In fact, less than 1% of the available genome assays are (of the ‘worrying variants’) Alpha, Beta and Gamma,” she said. Maria Van Kerkov, a senior executive of the WHO, answering questions from users on social networking sites.
“This virus (s.s. the Delta variant) has become more powerful, is more contagious and competes and replaces others on the market, “she added, according to AFP.
At present, however, the WHO describes all four of the above variants as “worrying”.
Until now, he considered four other “variations of interest”, the And, Iota, Kappa and Lambda, but the first three of them have declassified, said Van Kerkov.
