COVID-19: Dangerousness, spread in Europe, restrictions 3 new info on the omicron variant<

Research on the new variant is progressing, just like its spread.The presence of omicron is now confirmed in at least 15 American states, and some 40 countries around the world, after being first detected in South Africa.

Of the first "encouraging" signals on the severity of Omicron cases

The first "signals" from South Africa concerning the gravity of cases linked to the Omicron variant are "a little encouraging," Dr. Anthony Fauci, white house advisor on the health crisis, told AFP this Sunday on Sunday on Sunday on Sunday on Sunday on Sundaywhile warning that it was only preliminary data.

"Clearly, in South Africa, Omicron is more transmitted," he said during an interview on CNN, referring to the "vertical" curve of the number of new cases in this country."But so far, even if it is too early to draw definitive conclusions, it does not seem to have a high degree of gravity," he said."So far, the signals concerning gravity are a bit encouraging," he said.

Medical experts have however stressed in recent days that the demography of the South African population was particularly young, and that serious cases could be expected in the coming weeks.

Laboratory studies are underway to determine if and to what extent this new varying, which has very many changes worrying scientists, is more transmissible, capable of resisting immunity induced by a first infection or a vaccine, orcause more serious cases of the disease.

"I think there is a real risk that we can see a drop in vaccine efficiency," said Stephen Hoge, Moderna President on Sunday, echoing previous declarations of the CEO of the company, Stéphane Bancel.

"What I don't know is what scale," he said."Will this be what we saw with Delta, against which vaccines have remained effective, or will we see a drop in efficiency of around 50%, whichwould mean that we have to update them, "he said.Moderna, like other pharmaceutical companies including Pfizer, has already started work to adapt their vaccine if necessary.

The United States has for a week closed its border to this country as well as seven others from southern Africa.Anthony Fauci said this Sunday hoping that this ban be lifted "within a reasonable time".

An explosion of cases in Denmark: 183 confirmed cases

The number of confirmed cases of the new omicron variant of the virus responsible for the COVVI-19 jumped at 183 this Sunday in Denmark, announced the health authorities, qualifying the evolution of "worrying".At the last score on Friday, Denmark had only 18 confirmed cases and 42 suspicious cases, according to data from the SSI public institute, which means that the number of cases has at least tripled in 48 hours.

Before this announcement, the European Center for Disease Control and Prevention (ECDC) totaled 182 cases throughout the European Union, plus Norway and Iceland.

The Nordic country is one of the most equipped in Europe in terms of sequencing, allowing it to detect more cases and faster, without this means that the contagion is stronger than elsewhere."We observe a worrying increase in the number of cases of omicron infections in Denmark," said SSI director Henrik Ullum, in a press release.

"There are now contagion channels where the variant is detected in people who have not gone on a trip or summer in contact with travelers," he said.

The Institute works "intensely" to further accelerate the rapid results of laboratory tests, so that health institutions can trace contamination channels "as quickly as possible", adds the Health Management.

"The time we earn, we have to use it to vaccinate as many people as possible.Significant immunity gives more solidity to our society, if contamination to the omicron continues, "he argues.

New measures in Europe approaching the holidays

Several European countries tighten the screw in the face of this upward spread.
