ارے یہ پاکستانی قوم ہے اُمید کا دِیا جلائے رکھتی ہے۔
پاکستانی قوم اللہ تعالی کی مدد و نصرت سے حاصل کردہ امید اور اتحاد و اتفاق سے دنیا کے ہر بحران کا مقابلہ کر سکتی ہے۔

Indeed, strong clues had already emerged by
February 26, 2020, when a Perspectives piece was published in the New England Journal of Medicine. In the piece, David M. Morens, M.D. and Peter Daszak, Ph.D. from the National Institute of Health (NIH) and Jeffery K. Taubenberger, M.D., Ph.D. wrote: “Of course, scientists tell us that SARS-CoV-2 did not escape from a jar: RNA sequences closely resemble those of viruses that silently circulate in bats, and epidemiologic information implicates a bat-origin virus infecting unidentified animal species sold in China’s live-animal markets.”
This wasn’t exactly a case of same bat channel, same bat time. But the first, more deadlier SARS virus seemed to cause the 2002-2003 outbreak after it had managed to jump from bats to humans via intermediate hosts such as masked palm civets. Yes, some masked beings may have inadvertently partnered with bats to bring the original SARS virus to humans. So it wouldn’t be too surprising if something like that happened
again for SARS-CoV2.
Even more evidence of a natural rather than human-made origin for SARS-CoV2 has emerged from a study described in a research letter just published in Nature Medicine. In the letter, a research team described how they had analyzed the genetic sequences that code for the protein spikes on the surface of SARS-CoV2. The virus looks sort of like a medieval mace with multiple spikes sticking out from its spherical shape. These spikes aren’t just for show as the virus uses them to latch on to a cell that it wants to invade and then push its way into the cell.
Apparently, portions of these spike proteins are so effective in targeting specific receptors on human cells that it is hard to imagine humans manufacturing them, not with known existing technology. The researchers then concluded that this feature and thus the new coronavirus could have in all likelihood only evolved over time naturally. You see humans can make useful stuff like ride-sharing apps but are still quite puny compared to nature when it comes to making stuff like viruses.
In fact, the research team found that the SARS-CoV-2 structure in general is quite different from what humans would have likely concocted. If a human had wanted to create a viral weapon, he or she would have started with the structure of a virus that’s already known to cause illness in people. Naturally, if you want to make a weapon, you may want to start with something like a grenade launcher rather than a smoothie maker, not that the virus looks like either. Instead, the structure of SARS-CoV2 is quite similar to those of viruses known to infect bats and pangolins.

Of course, scientists tell us that SARS-CoV-2 did
not escape from a jar: RNA sequences closely resemble those of viruses that silently circulate in bats, and epidemiologic information implicates a bat-origin virus infecting unidentified animal species sold in China’s live-animal markets. We have recently seen many such emerging zoonoses, including the 2003 bat-coronavirus–derived SARS (an earlier severe acute respiratory syndrome, caused by a closely related coronavirus), which came terrifyingly close to causing a deadly global pandemic that was prevented only by swift global public health actions and luck.1 Now, 17 years later, we stand at a similar precipice. How did we get to this point, and what happens next?
We have actually been watching such dramas play out in slow motion for more than a millennium in the case of pandemic influenza, which begins with viruses of wild waterfowl that host-switch to humans and then cause human-to-human transmission. A bird virus thereby becomes a human virus. Coronavirus emergence takes a different trajectory, but the principles are similar: SARS, the Middle Eastern respiratory syndrome (MERS), and Covid-19 all apparently have their origins in enzootic bat viruses. The parallels between the two SARS viruses are striking, including emergence from bats to infect animals sold in live-animal markets, allowing direct viral access to crowds of humans, which exponentially increases opportunities for host-switching. Such live markets have also led to avian epizootics with fatal human “spillover” cases caused by nonpandemic, poultry-adapted influenza viruses such as H5N1 and H7N9. One human cultural practice in one populous country has thus recently led to two coronavirus near-pandemics and thousands of severe and fatal international cases of “bird flu.”
