Covid cases up 63%: What to know about Ómicron’s new subtype Pirola

Cases of receiving persons Detection of COVID in the world They have grown back. In last week’s report, the World Health Organization (WHO) Nearly 1.5 million new confirmed cases and counting 2,000 deaths on the planet.

These figures show that there was 63% increase in cases, but there was a 48% decrease in deaths compared to the previous 28 days. The United Nations Health Organization has also clarified This report has limitations because not all countries test people with symptoms Not reporting information or tracking the coronavirus genome continuously.

“Covid-19 continues to be a significant threat. WHO urges Member States to maintain and not dismantle existing infrastructure in response to Covid-19.”Experts said in their weekly report.

In Argentina too, the number of Covid cases has increased From the second half of July till now. Compared to the number of cases registered in the previous two years, though the volume was low, the Ministry of Health of the country, He said There was a “slight increase” in notifications.

In the week of July 17, the country had a weekly average of 77 confirmed cases by date of onset of symptoms. Instead, the weekly average was 172 confirmed cases in the week of August 14, according to the Doctor’s analysis. George Aliaga of the National University of Hurlingham, based on data from the Health Portfolio.

The increase in covid cases worldwide is related Subsequences of omicron variation dominate the spread of the virus. WHO currently monitors three subspecies in its “Variant of Interest” category: XBB.1.5, XBB.1.16 and EG.5. The latter is popularly known as Eris. He has 7 more sub-lines in the pipeline. One of hers PA.2.86Some experts have already called Byrola informally.

As of August 23, only nine BA.2.86 variant sequences from five countries have been uploaded to the GISAID platform. To date, WHO has not notified There is no death In cases diagnosed with Pyrola. Additionally, two countries (Switzerland and Thailand) found this sublineage in samples. Sewage water.

“This variant with multiple mutations has now appeared in many places, at a time when genetic and wastewater monitoring has greatly decreased worldwide,” the scientist said. Eric Topol, founder and director of the Scripps Translational Research Institute.

He Byrola supplement found in Israel, Denmark (3 persons), United Kingdom, USA (two people, one from Japan) and South Africa. “It is safe to say that the presence of BA.2.86 is widespread around the world at this time,” Topol said in his newsletter.

It is not yet known how contagious the Pyrola sublinage will be, but he clarified that this is the key to how it all works. Looking at Omicron’s early days in November 2021, it has already announced its high penetration in South Africa.”

However —Topol highlighted— today the same situation is not found in Pirola: “That is somewhat reassuring. In Denmark, where genetic surveillance is strong, another week has gone by without any new detections since BA.2.86, so that is encouraging. But worldwide prevalence may be higher than so far detected because Our awareness has reached a dead end”.

Pirola (BA.2.86) is out In the family tree of variants, because of how much it has changed. presents More than 30 mutations In its spike protein, part of the virus passes through the cell and vaccines train the body to fight back. Experts believe that antibodies generated by infection with earlier variants will have difficulty recognizing the new sublineage.

When asked by infobae About him Sub-order BA.2.86Senior Researcher in Immunology Conizet from ArgentinaDoctor George Jeffner, Konizetin, Interim Director of the Institute for Biomedical Research on Retroviruses and AIDS (INBIRS) and the University of Buenos Aires, said: “The number of mutations is striking, which is why it is good to do global surveillance. But the data is still preliminary. It remains to be seen how these BA.2.86 mutations affect their biological behavior. It is about its infectiousness, transmissibility, ability to evade the immune system and the severity of the disease it causes. We need more data.”

“It can avoid not only antibodies, but also a memory response by T cells. It is this last response that mediates protection against acute conditions,” he pointed out. “Therefore, it would be a concern if the virus could effectively evade the T response. This is very difficult to predict,” he added.

As a measure, Zeffner emphasized, “we must not abandon the surveillance of circulating subtypes. Although severe cases and mortality have decreased compared to previous years, thanks to the vaccine, today at this stage of the epidemic Tests should be carried out in some important hospital institutions to find out what percentage of respiratory symptoms are due to coronavirus”, Jeffner pointed out.

And – he advised – “To monitor the coronavirus, which has already given us unpleasant surprises, more waste water monitoring should be done in communities. The whole world should continue to rigorously study the coronavirus.
