State of the Globe: Aerosol Boxes in Intensive Care - A Boon or a Myth.

The very data suggests that this particular variant was not only highly contagious, spreading like wildfire but was also virulent enough to cause such a degree of catastrophe to the entire human race. The case fatality ratio varied as the disease progressed (being >20% at outset in Wuhan to almost <5% after a year in Wuhan, attributable to better understanding of the disease and improved care).[3] Furthermore, the overall case fatality ratio varied with different countries (ranging from 2% to 10%).[4] Thus, with such transmissibility and significantly high case fatality rate, the disease forced the authorities and the health-care systems all over the world to put forward plans to curb the spread and lessen the mortality in a hurry. Health-care workers were the frontline warriors and a WHO estimate showed that 80,000–180,000 health-care workers died because of the disease between January 2020 and May 2021.[5]
