First image of Omicron variant shows many more mutations than Delta

ITALY, SOUTH AFRICA: The new COVID variant Omicron has many more mutations than the Delta variant, according to a first “image” of this new variant initially detected in South Africa, produced and published by the prestigious Bambino Gesu hospital in Rome.

On the three-dimensional “image”, which looks like a map, “we can clearly see that the Omicron variant presents many more mutations than the Delta variant, concentrated above all in one area of the protein that interacts with human cells”, the team of researchers said in a statement Sunday.

“This does not automatically mean that these variations are more dangerous, just that the virus has further adapted to the human species by generating another variant,” the researchers said.

“Other studies will tell us if this adaptation is neutral, less dangerous or more dangerous,” they added.

The research team focused on the search for mutations in “the three-dimensional structure of the spike protein”, Claudia Alteri, professor of clinical microbiology at Milan State University and a researcher at Bambino Gesu, told AFP.

The image was produced “from the study of the sequences of this new variant made available to the scientific community” coming mainly “from Botswana, South Africa and Hong Kong”. Meanwhile, the Omicron coronavirus variant spread around the world on Sunday, with new cases found in the Netherlands, Denmark and Australia even as more countries imposed travel restriction to try to seal themselves off.

The detection of Omicron triggered global alarm as governments around the world scrambled to impose new travel curbs and financial markets sold-off, fearing the variant could resist vaccinations and upend a nascent economic reopening after a two-year global pandemic.

Omicron, dubbed a “variant of concern” last week by the WHO that is potentially more contagious than previous variants, has now been detected in Australia, Belgium, Botswana, Britain, Denmark, Germany, Hong Kong, Israel, Italy, the Netherlands, France, Canada and South Africa.

The top US infectious disease official, Dr. Anthony Fauci, told President Joe Biden on Sunday it will take about two weeks to have more definitive information about the transmissibility and other characteristics of Omicron, the White House said in a statement, adding that Fauci believes existing vaccines “are likely to provide a degree of protection against severe cases of COVID”.

The new variant has also thrown a spotlight on huge disparities in vaccination rates around the globe. Even as many developed countries are giving third-dose boosters, less than 7% of people in poorer countries have received their first COVID-19 shot, according to medical and human rights groups.
