Now, with Omicron? Even with HEPAs in the corridor?
Transmission.
Now, they did point out the index case was not wearing a mask, or just a cloth mask, when they opened the door to get food or drop off the garbage in the corridor.
But was that the most likely root-cause?
No, a smoke test indicated that it was NOT air pouring under the door, but from when the doors were opened.
The most studied and given vaccinations in history?
Or a disease that causes tremendous endothelial damage that ends up causing acute ischemic strokes, intracerebral hemorrhages, low oxygen?
Occam's razor cuts it to the latter.
CoVid has been documented to cause altered mental status, dehydration, hyperventilation (low {xygen), and low blood sugar here: sciencedirect.com/science/articl…
Low blood pressure from Intracranial hemorrhage (itself enough to take you down, obviously).
