Institutions said yesterday that an initial purchase of the dexamethasone drug belonging to the steroid family, which has proven effective in treating patients with severe symptoms of Covid-19, will provide the drug to up to 4.5 million people in low and middle income countries, while a study showed that the copy The current virus is more "infectious" than before.

In detail, a joint statement said that the United Nations Children's Fund (UNICEF) is negotiating a pre-purchase under an agreement led by the charitable foundations of Unit-Aid and Wellcome, as part of the World Health Organization's plan to accelerate the delivery of treatments to patients around the world.

"We are seeking this pre-purchase to ensure fairness in low and middle income countries receiving treatment for (COFED-19) with dexamethasone, which can save lives and avoid the shortfall caused by high demand rates," said Philippe Denoton, Acting Executive Director of Unit-Aid. From other regions of the world ».

This comes at a time when a study published by the Journal of Cell showed that the current version of the current coronavirus circulating in cells affects more cells than those that were initially spread in China, which made them more cause of infection in humans, although this still needs to be proven.

"We do not yet know whether or not a person is better tolerating this version," Anthony Fawcci, director of the Institute of Infectious Diseases in the United States, told Gamma Magazine. However, the virus appears to be replicating more and its infection may be stronger, but we are still confirming this. There are senior scientists in the genetics of the virus working on it. ”

After its exit from China and its arrival in Europe, the new version of the virus, which turns like all other viruses, became dominant, and this European version later moved to the United States. The mutated version, called the D614G, includes a single letter of the virus’s DNA in a place that controls the head that enters human cells.

Researchers around the world are investigating the genetic changes of the virus.

The new study was conducted by researchers from the University of Sheffield and Duke and the National Laboratory in Los Alamos. They found that D614G had become dominant and expressed concern that the transformation was making the virus "more transmissible." They presented the results of their work online on a website dedicated to research and scientific studies before being officially published.

However, this result was criticized, because the team did not prove that the transformation in itself is the reason for the dominance of this version of the virus, and may have benefited from other factors or came by chance, so these scientists conducted additional work and experiments at the special request of the publishers of the magazine "Ciel".

The scientists first analyzed the data of 999 British patients who were hospitalized with "Covid-19", and found that those who had contracted the mutant virus had more viral particles without affecting the severity of their infection, which was encouraging news.

On the other hand, experiments in the laboratory have shown that the mutated version of the virus is able to infect human cells three to six times more.

"It seems likely that it is a more capable virus," said Erika Ullmann-Sapphire, who conducted one of these experiments in "La Joya Institute for Immunolodgy", but all of that remains "in the weighting field" as experiment in the tube cannot simulate the actual dynamics of a pandemic. But it can be said at a minimum that the newly emerging coronavirus is "more contagious", but this does not mean that its infection is transmitted more between people.

"A copy is now a pandemic," wrote Nathan Groppo of Yale University and his colleagues in a separate article. He added that the new version "should not change anything with protective measures or aggravate individual injuries."

He added, "We are witnessing a real-time scientific work. This is an interesting discovery, and it could affect millions of people, but we still do not know its ultimate impact. We discovered the virus six months ago and we will continue to learn a lot about it in the next six months. ”
