More SA data.
Still same position:
#Omicron causes less severe disease in SA. 3 possible reasons: 1. High levels of natural immunity 2. Better vax coverage 4 Omicron vs. Delta wave 3. Omicron = less virulent (makes people less sick) We need more data to know the reason
The SA hospitalisation data includes data on oxygenation and ventilation. There are around 1,500 cases in a nation of 60m. That fits lab evidence of a different clinical progression of omicron...not so effective at attacking lung tissue
