The new ‘Deltacron’ variant is rare, report says

 

Covid - Deltacron - new variant


A hybrid of the Omicron and Delta variants of Covid-19 has been found in several countries of the world. On March 10, 33 samples of the new variant were reported in France, Denmark, Germany, and the Netherlands.

In February, Scott Nguyen, a scientist with the Washington, D.C., Public Health Laboratory, found samples collected in France in January that researchers had identified as a mix of Delta and Omicron variants. However, the scientist said that each virus in the sample carried a combination of genes from the two variants. Scientists reportedly call such viruses recombinants.

In some cases, people can be infected by two variants of Covid-19 at once.

World Health Organization (WHO) also confirmed the emergence of a new Covid-19 variant. WHO Covid-19 technical lead, epidemiologist Dr Maria Van Kerkhove, spoke about the Deltacron (a mix of Delta and Omicron variants) variant last week. She said that the new variant has been detected in a few countries. However, she said not to panic because records of the virus are low.

Reportedly, the patients of the new variant, described in the aforementioned report, were infected with the combination of the spike protein from an Omicron variant and with the "body" of the Delta variant. The spike protein is also the main target of antibodies produced through infections and vaccines.

The WHO Covid-19 technical lead said that Delta and Omicron recombinant virus is expected because of the "intense circulation" of both variants. According to scientists, recombinant viruses are extremely rare. The virus has existed since January but it has not shown the ability to grow exponentially.

Philippe Colson, a researcher who published a report on three cases of the Deltacron variant in France, told Reuters that it's too early to know if Deltacron will cause severe disease or not. Reportedly, some scientists are referring to the new hybrid as the AY.4/BA.1 recombinant.

Russian central bank hikes rates amid the Ukrainian crisis

  Russia's central bank on Monday raised its key policy rate to 20 per cent from 9.5 per cent amid the Ukrainian crisis. The western countries imposed harsh sanctions against the country, which affected the Russian economy. The central bank also ordered companies to sell 80 per cent of their foreign currency revenues to manage the fallout of harsh economic sanctions. The West pummelled the country with economic sanctions over Russia’s invasion of Ukraine . Reportedly, the central bank said in a statement that external conditions for the Russian economy have drastically changed after Russia invaded Ukraine.
