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.
A two week puke cruise from South Hampton to the Canary Islands with 3,077 other guests, 1,205 crew members, and 1 apparently greedy cruise ship company (?) -@pandocruises.
How does a 5 HOUR WAIT to call the ship doc sound?
Dr. Marr wrote this. I respect her immensely, but completely disagree on this topic.
- She does not know the ventilation/filtration of every airport. She does not know who was just sitting in that spot moments before you found it. Aerosol stability, physics of aerosols,
speed of ventilation/filtration all agree with me on this. The Australian Church study of 45 feet transmission facing away agrees.
- On airplanes - the Harvard Aviation Public Health Initiative (APHI) disagrees with her, indicating masks are necessary
- On coughing, she might not be aware of the 58% presymptomatic transmission.
-Overall, she might not be aware of the:
✅ 38% LongCovid risk after 3 infections.
✅ It only takes one virion to start a covid infection (tight transmission bottleneck).
