It may take weeks to unravel the mysteries of the Omicron Govt variant
The epidemic-stricken world faces weeks of chaotic uncertainty as nations restrict travel and take other measures to prevent the new deadly coronavirus strain before Omigran realizes how dangerous it is. Will it spread faster than the already spreading delta variant? Will it make people sick? Will this prevent the protection of vaccines or re-infect survivors? There is a lot of speculation, but there is no hard evidence that scientists are rushing to find answers amidst the research of the interested public. Trevor Bedford, who studies the evolution of the coronavirus at the Fred Hutchinson Cancer Research Center, described the reactions of health professionals as "the exact stage of mania". Omicron "may not turn out as bad as we imagined, but I think it's perfectly appropriate to deal with it this time," he said. Until now, the world has been slowly reacting to every coronavirus curve. The early warning of South Africa and Botswana at this time may have provided an important start. "Hard to know: Did we simply understand reality, and now the world appears to be changing at an appropriate pace?" Asked Dr. Jacob Lemieux, who oversees variations on research collaboration led by the Harvard Medical School. Why worry? Omicron raised the alarm because of the greater number of mutations than the previous variants. The spike protein that allows the virus to attach to human cells maybe 30 in a key location. Scientists identify some mutations from earlier variants that are more resistant to infection or vaccine. But they never saw the crowd of these particular changes. According to Dr. William Moss of the Johns Hopkins Bloomberg School of Public Health, most are highly specific to the virus. . " “It’s a balance,” Moss said. "We want to take this seriously because of the combination of mutations, but we do not want to panic and we do not want to act too much until we know more about this virus." Wandering for answers Scientists still have little data on whether Omigron causes more serious diseases than other types. Although it has already been detected in many countries a few days after its discovery was announced, it is too early to know how contagious it is. The alpha variant that appeared a year ago is more contagious than the virus that started the infection. Then the delta struck, much more contagious than the Alpha. It's not clear how Omigron will compete in a place like the United States, and that strong delta variant causes more than 99% of current COVID-19 cases, said Louis Monsky, director of the Institute of Molecular Virology at the University of Minnesota. Even in some parts of South Africa, the increase in cases caused by Omigran does not indicate that the mutant is more contagious than the delta, Lemieux said. “We don’t know if Omigron will leave the delta or become a dominant strain in a few places due to chance,” he said. To better understand Omigron, scientists are trying to figure out how it came to be. This is not a descendant of Delta. A popular theory is that someone with a severely weakened immune system had a coronavirus infection that they could not move for long, and the mutations were stacked. “It’s totally weird,” Bedford said, adding that the variations that were in circulation in the summer of 2020 appear to be close relatives of Omicron. They change every time the virus spreads, and with a bad COVID-19 test, Omigran may be boiling undetected. But as the immune-compromised body fights a virus, its sudden appearance may be the result of a cat-and-mouse struggle, Bedford says, by repeatedly modifying its spike protein to avoid detection. (Bedford receives funding from Howard Hughes Medical Institute, which also supports the Associated Press Health and Science Department.) What to look for Scientists say it could take two to four weeks to get some important answers. One of the biggest concerns is how much immunity Omigran can avoid. So far the beta variant has been the biggest challenge for vaccine protection but fortunately, that strain has not spread widely. "This new variant is unlikely to have survived all of the antibodies produced following the vaccine," said E.J., an immunologist at the University of Pennsylvania. Said, John Verry.
