‘The first piece of good news is that this wave might be shorter lived than those of other variants. Every country is different, of course, with different population structures and different levels of immunity, both “natural” and from vaccination. But in South Africa, it appears that, while test positivity is still growing throughout the country, in the Omicron epicenter of Guateng the wave may be peaking already, with cases and hospital admissions both taking a visible turn, barely three weeks since the variant was first publicly announced and just five weeks since the first likely case. …
The second piece of good news is that as the wave progresses in South Africa, the cases continue to appear mild. …
And the third piece of good news is that we now have a possible biological explanation for reduced severity, which gives the observed preliminary data another layer of plausibility. That comes from research by the University of Hong Kong, which finds that the new variant is much more efficient in reproducing in the upper respiratory tract, where you can cough and sneeze it out onto others, and much less efficient in the lungs, where it will be most dangerous to the infected host….’
