"Even if the risk of any one infected person being hospitalised or dying is lower with Omicron than with Delta, a much higher total number of infected people could still mean very high levels of death and hospitalisation overall. Do you shed it more efficiently and spew more of it out so you can infect more people? Immune system evasion, on the other hand, is the capacity of the virus to avoid antibodies that would otherwise mark it for destruction by the body, as well as an ability to dodge various immune system cells. That change was announced in late December, before the height of the omicron peak in the U.S. In a study examining the Omicron variant published on December 31 by the US Centers For Disease Control (CDC), the median time between exposure and onset of symptoms was found to be three days.
