The Omicron variant of the coronavirus, which spearheaded the third wave of the pandemic, is slowing down around the world. Many governments are loosening the rigorous controls put in place to keep the disease from spreading. However, a World Health Organization (WHO) expert has expressed a new alarm about a sub-strain of Omicron.

"The virus is mutating, and we're tracking many sub-lineages of Omicron." BA.1, BA.1.1, BA.2, and BA.3 are the four levels. At a briefing on Thursday, Maria Van Kerkhove, Covid-19 technical lead at the WHO, stated, "It's really pretty astonishing how Omicron, the current variety of concern, has overtaken Delta over the world." The World Health Organization (WHO) shared the video on Twitter.

"This sub-lineage BA.1 accounts for the majority of the sequences." "We're also witnessing a rise in the proportion of BA.2 sequences," she noted. According to the WHO, about 75,000 deaths from Covid-19 were reported last week, according to a tweet that accompanied the video. The WHO official expressed alarm about one sub-lineage, saying that "BA.2 is more transmissible" than the others. "We are observing," Kerkhove said, adding that there is no proof that BA.2 is more dangerous than BA.1.

Finally, according to the WHO official, Omicron is not moderate, although it is less severe than Delta. "We're still seeing a considerable number of Omicron hospitalizations." We are witnessing a large number of deaths. It is neither a common cold nor influenza. "Right now, we just have to be really cautious," Kerkhove added.

The WHO announced in a tweet that nearly 75,000 deaths from Covid-19 were reported to them last week. According to the WHO, BA.2 currently accounts for nearly one out of every five new Omicron cases worldwide.

The WHO stated in a press conference on Tuesday that a fresh wave of infections caused by the Omicron strain of the coronavirus is advancing eastward, asking authorities to increase vaccination and other measures. Cases of Covid-19 have more than doubled in Armenia, Azerbaijan, Belarus, Georgia, Russia, and Ukraine in the last two weeks, according to WHO's Europe regional director Hans Kluge.

  Mumbai: The Indian Space Research Organisation (ISRO) announced on Wednesday that the Large Area Soft X-ray Spectrometer (CLASS), a payload on board the Chandrayaan-2 Orbiter, had discovered solar proton events (SPEs), which considerably increase radiation exposure to humans in space. Coronal mass ejections (CMEs), a tremendous torrent of ionised material and magnetic fields that reach Earth a few days later, causing geomagnetic storms and lighting up the polar sky with auroras, were also observed by the sensor on January 18. According to the ISRO, such multi-point measurements helps in the understanding of propagation and its impact on various planetary systems. Solar flares are dramatic explosions that occasionally spew out energetic particles (called Solar Proton Events or SPEs) into interplanetary space when the Sun is active. The majority of these are high-energy protons that have an influence on space systems and increase radiation exposure to astronauts. According ...
